Section 2: Description of SBE 19plus V2
This section describes the functions and features of the SBE 19plus V2
SEACAT Profiler, including system description and auxiliary equipment,
specifications, dimensions and end cap connectors, batteries and battery
endurance, external power and cable length limitations, data storage,
communication settings, magnetic reed switch, and configuration options
and plumbing.
System Description
The SBE 19plus V2 SEACAT Profiler is designed to measure conductivity,
temperature, and pressure in marine or fresh-water environments at depths up
to 7000 meters (22,900 feet). The 19plus V2 operates in two modes:
• Profiling mode for acquiring vertical profiles. The 19plus V2 runs
continuously, sampling at 4 scans per second (4 Hz). It can average up to
32,767 samples, storing and transmitting only averaged data.
• Moored mode for acquiring time series measurements once every
10 seconds to every 4 hours, adjustable in 1-second increments. Between
samples, the 19plus V2 powers down, drawing only 20 microamps.
Self-powered and self-contained, the 19plus V2 features the proven Sea-Bird
conductivity and temperature sensors and a precision, semiconductor, straingauge pressure sensor. Nine D-size alkaline batteries provide 60 hours
operation in Profiling mode; the 64 Mbyte FLASH RAM records 400 hours of
conductivity, temperature, and pressure data while sampling at four scans per
second (other configurations/setups vary). The 19plus V2 three-wire RS-232C
interface provides simultaneous, real-time monitoring. User-selectable output
format is raw data or engineering units, in hexadecimal or decimal form; XML
output is also available. Setup, diagnostics, and data extraction are performed
without opening the housing. The 19plus V2 can power and acquire the
outputs of external sensors.
Logging is started by sliding the On/Off switch, by command via the RS-232
interface, or by applying external power, depending on your instrument setup.
A standard 19plus V2 is supplied with:
• Plastic housing for depths to 600 meters (1950 feet)
• 64 Mbyte FLASH RAM memory
• Internally mounted strain-gauge pressure sensor
• 9 D-size alkaline batteries (Duracell MN1300, LR20)
• Impulse glass-reinforced epoxy bulkhead connectors:
- one 6-pin connector for data I/O, external power, and pump power;
- three 6-pin connectors, for two differential auxiliary A/D inputs each;
- one 4-pin connector, for RS-232 auxiliary sensor (SBE 38 secondary
temperature sensor, WET Labs sensor [single, dual, or triple channel ECO
sensor; WETStar; or C-Star], up to two Pro-Oceanus Gas Tension
Devices, or Aanderaa Oxygen Optode 4330 or 4835)
• T-C Duct, which ensures that Temperature and Conductivity
measurements are made on the same parcel of water
• SBE 5M miniature pump (with plastic housing for depths to 600 meters)
for pumped conductivity; by fixing the flow to a constant rate, the pump
ensures a constant conductivity time response. The T-C duct and pump
combination results in dramatically lower salinity spiking.

• The SBE 32 Carousel is a 12-,
24-, or 36-bottle water sampler.
The SBE 55 ECO is a 3- or 6-bottle
water sampler.
• Seasave 7.18 or later also supports
acquisition of data from a NMEA
device connected directly
to the computer (instead of the
deck unit).
•
SBE 32 Carousel Water Sampler and SBE 33 Carousel Deck Unit OR
SBE 55 ECO Water Sampler and SBE 33 Carousel Deck Unit The SBE 32 or SBE 55 provides +15 VDC power to the 19plus V2 and
has ample power for auxiliary sensors not normally supported by batterypowered CTDs. CTD data from the 19plus V2 is converted into singlewire telemetry for transmission over long (10,000 meter [32,800 feet]) sea
cables. Bottles may be closed at any depth without interrupting CTD data
via software control using the Seasave program or from the front panel of
the SBE 33 Deck Unit. See the SBE 33 manual for operating details.

SBE 36 CTD Deck Unit and Power Data Interface Module (PDIM) These items provide power and real-time data handling capability over
single-conductor sea cables using the same method employed in the
SBE 32/SBE 33. The PDIM is a small pressure housing that is mounted on
or near the 19plus V2. It provides +15 VDC power to the 19plus V2 and
interfaces two-way RS-232 communications from the 19plus V2 to the
telemetry used on the sea cable. See the SBE 36/PDIM manual for
operating details.
•
SBE 32 Carousel Water Sampler and Auto Fire Module (AFM) - The
AFM, mounted on or near the 19plus V2, allows the SBE 32 to operate
autonomously on non-conducting cables. The AFM supplies the power,
logic, and control commands to operate the SBE 32. The AFM monitors the
pressure data recorded by the 19plus V2 in real-time, closing water sampler
bottles at predefined pressures (depths) or whenever the system is stationary
for a specified period of time. Bottle number, firing confirmation, and five
scans of CTD data are recorded in the AFM memory for each bottle fired.
See the AFM manual for operating details.
Note:
Seasave 7.18 or later also supports
acquisition of data from a NMEA
device connected directly to the
computer (instead of the deck unit).

*Notes on Quartz Pressure Sensor Resolution:
Pressure Sensor Resolution = Sensitivity * Counter Resolution
•
Sensitivity = ∆ pressure / ∆ frequency
where ∆ pressure is change in pressure in desired units (psia, db, meters, etc.) = pressure sensor full scale range
∆ frequency is change in frequency in Hz ≈ 3000 Hz over sensor’s full scale range
•
Counter Resolution = pressure sensor output frequency / (integration time * 1,843,200)
where pressure sensor output frequency ≈ 35,000 Hz
Integration time = 0.25 seconds
(requires NAvg= even number for Profiling mode; requires NCycles= even number for Moored mode)
•
To convert pressure units: db = psia / 1.45
•
Increasing NAvg= (Profiling mode) or NCycles= (Moored mode) reduces the measurement noise.
Example: What resolution can be obtained for a 7000 meter (10,000 psia) Quartz pressure sensor?
Sensitivity = ∆ pressure / ∆ frequency = 7000 m / 3000 Hz = 2.333 m / Hz
Counter Resolution = pressure sensor output frequency / (integration time * 1,843,200) = 35,000 Hz / (integration time * 1,843,200)
= 35,000 Hz / (0.25 seconds * 1,843,200) = 0.076 Hz
Resolution = Sensitivity * Counter Resolution = 2.333 db/Hz * Counter Resolution
= 2.333 db/Hz * 0.076 Hz = 0.18 db ≈ 0.18 m = 180 mm

SBE 19plus V2
Sample Timing (Moored Mode)
Notes:
• See moored mode sampling times
in Specifications.
• Sample timing information is
approximate.
• See Battery Endurance for power
limitations.
Sample timing in Moored Mode is dependent on a number of factors, including
the 19plus V2 pressure sensor type – strain gauge or Quartz, setup for the pump
(MooredPumpMode=), and user-programmable sampling parameters for
number of samples per measurement (NCycles=) and delay before sampling to
allow time for auxiliary sensors to stabilize (DelayBeforeSampling=).
For autonomous sampling (logging), the 19plus V2 requires a minimum of
5 seconds from the end of one sample to the beginning of the next sample. After
it takes each sample, it checks the time for the start of the next sample, based on
the user-programmable sampling interval (SampleInterval=). If there is less
than 5 seconds remaining until the programmed start of the next sample, the
19plus V2 provides a message:
Error - - > alarm time not far enough in the future,
resetting alarm to 5 sec from now
The 19plus V2 takes the next sample in 5 seconds. The 19plus V2 performs this
check after each sample; because of small variations in sampling time, this can
cause samples to be taken at uneven intervals. Therefore, best practice is to
check the sample timing before you set up the instrument, to ensure that the
sample interval is long enough.
Examples are shown below:
Example 1 - pump on for 0.5 sec before each sample (MooredPumpMode=1), strain gauge pressure sensor,
1 measurement/sample (NCycles=1):
Sampling time = 0.5 sec (pump before sampling) + 2.5 sec (basic sampling time for strain gauge) = 3.0 sec
Minimum sample interval (SampleInterval=) = 3.0 sec + 5 (sec between samples) = 8.0 sec < 10 sec minimum,
so minimum SampleInterval=10.
Example 2 - pump on during sample (MooredPumpMode=2), 15 sec delay before sampling (DelayBeforeSampling=15),
Quartz pressure sensor, and 4 measurements/sample (NCycles=4):
Sampling time = 15 (delay before sampling) + 2.45 (basic sampling time for Quartz) +
(4 – 1) * 0.25 (additional measurements/sample for NCycles) = 18.2 sec
Minimum sample interval (SampleInterval=) = 18.2 sec + 5 (sec between samples) = 23.2 sec,
so minimum SampleInterval=25 (round up by a few seconds, to account for any small differences in sample timing).

Batteries
Notes:
• See Replacing / Recharging
Batteries in Section 5: Routine
Maintenance and Calibration.
• As of 2011, the Ni-Cad battery pack
and charger are no longer available.
For the main battery, the SBE 19plus V2 uses nine D-cell alkaline batteries
(Duracell MN 1300, LR20), or rechargeable Nickel Metal Hydride (NiMH) or
Nickel-Cadmium (Ni-Cad) batteries. If necessary, carbon-zinc or mercury cells
can be used.
On-board lithium batteries (non-hazardous units that are unrestricted for
shipping purposes) are provided to back-up the buffer and the real-time clock in
the event of main battery failure or exhaustion. The main batteries may be
replaced without affecting either the real-time clock or memory.
Battery Endurance
Notes:
• See Specifications for power
requirements.
• If the 19plus V2 is logging data and
the battery voltage is less than the
battery cut-off, the 19plus V2 halts
logging and displays a low battery
indication in the data. See
BatteryType= command in
Command Descriptions in Section 4:
Deploying and Operating SBE
19plus V2 for cut-off values for
various battery types.
• See Data Storage and Specifications
for data storage limitations.
The standard alkaline battery pack has a nominal capacity of 14 amp-hours;
for planning purposes, Sea-Bird recommends using a conservative value of
10.5 amp-hours. The optional NiMH battery pack has a nominal capacity of
8 amp-hours. The optional Ni-Cad battery pack (no longer available) has a
nominal capacity of 4.4 amp-hours.
Current consumption and sampling times vary greatly, depending on:
• instrument configuration - inclusion of optional SBE 5T or 5P pump and/or
auxiliary sensors, and
• user-programmed sampling parameters - Profiling or Moored mode;
if in Moored mode, the pump mode, number of measurements per sample,
and delay before sampling influence power consumption.
Examples are shown below for several sampling schemes for both Profiling and
Moored mode. For Moored mode, you can use the Deployment Endurance
Calculator to determine the maximum deployment length, instead of
performing the calculations by hand.
Profiling Mode Examples
Example 1 - standard alkaline batteries, SBE 5M pump, no auxiliary sensors
Sampling current = 70 mA (from Specifications)
Pump current = 100 mA (from Specifications)
Maximum sampling time ≈ 10.5 amp-hours / (0.070 amps + 0.100 amps) ≈ 61 hours
Example 2 - standard alkaline batteries, optional SBE 5T pump, auxiliary sensors drawing 100 mA
Sampling current = 70 mA (from Specifications)
Pump current = 150 mA (from Specifications)
Auxiliary sensor current = 100 mA
Maximum sampling time ≈ 10.5 amp-hours / (0.070 amps + 0.150 amps + 0.100 amps) ≈ 32 hours

SBE 19plus V2
Moored Mode Examples
A 19plus V2 with strain-gauge pressure sensor and standard alkaline batteries is set up to sample autonomously every
10 minutes (6 samples/hour). How long can it be deployed?
Example 1 – SBE 5M pump on for 0.5 sec/sample (MooredPumpMode=1), no auxiliary sensors,
1 measurement/sample (NCycles=1):
Sampling current = 70 mA * (2.5 sec + 0.5 sec) = 0.21 amp-sec/sample
In 1 hour, sampling current = 6 * 0.21 amp-sec/sample = 1.26 amp-sec/hour
Pump current = 100 mA * 0.5 sec = 0.05 amp-sec/sample
In 1 hour, pump current = 6 * 0.05 amp-seconds/sample = 0.3 amp-sec/hour
Quiescent current = 20 microamps = 0.02 mA
In 1 hour, quiescent current ≈ 0.02 mA * 3600 sec/hour = 0.0.072 amp-sec/hour
Current consumption / hour = 1.26 + 0.3 + 0.072 = 1.63 amp-sec/hour
Capacity = (10.5 amp-hours * 3600 sec/hr) / (1.63 amp-sec/hour) = 23190 hours = 966 days = 2.6 years
However, Sea-Bird recommends that batteries should not be expected to last longer than 2 years in the field.
Example 2 - optional SBE 5T pump on during sample (MooredPumpMode=2), 15 sec delay before sampling
(DelayBeforeSampling=15), auxiliary sensors drawing 100 mA, 4 measurements/sample (NCycles=4):
On-time = 2.5 + 15 (delay before sampling) + (4 – 1) * 0.25 (additional measurements/sample) = 18.25 sec
Sampling current = 70 mA * 18.25 sec = 1.28 amp-sec/sample
In 1 hour, sampling current = 6 * 1.28 amp-sec/sample = 7.7 amp-sec/hour
5T Pump current = 150 mA * 18.25 sec = 2.74 amp-sec/sample
In 1 hour, pump current = 6 * 2.74 amp-sec/sample = 16.4 amp-sec/hour
Auxiliary sensor current = 100 mA * 18.25 sec = 1.82 amp-sec/sample
In 1 hour, auxiliary sensor current = 6 * 1.82 amp-sec/sample = 10.9 amp-sec/hour
Quiescent current = 20 microamps = 0.02 mA
In 1 hour, quiescent current ≈ 0.02 mA * 3600 sec/hour = 0.072 amp-sec/hour
Current consumption / hour = 7.7 + 16.4 + 10.9 + 0.072 = 35.1 amp-sec/hour
Capacity = (10.5 amp-hours * 3600 sec/hr) / (35.1 amp-sec/hour) = 1076 hours = 44 days = 0.12 years

Section 2: Description of SBE 19plus V2
SBE 19plus V2
External Power
The SBE 19plus V2 can be powered from an external source (9 - 28 volts DC)
through the Y-cable connected to the Data I/O, Pump, and External Power
bulkhead connector on the sensor end cap. The internal battery pack is diodeOR’d with the external source, so power will be drawn from whichever
voltage source is higher. The 19plus V2 can also be operated from the external
supply without having the internal battery pack installed. Electrical isolation of
conductivity is retained in units powered externally, preventing ground loop
noise contamination in the conductivity measurement.
On the ship, cables longer than 3 meters should be installed inside an earthed
metal conduit by a qualified electrician. This minimizes the potential for
external signals to disrupt communication and ensures that high voltage lines
(such as the sea cable) are sufficiently protected. Cables shorter than 3 meters
can be used without shielding when installing or bench testing the instrument.
Cable Length and External Power without Deck Unit
Note:
See Real-Time Setup in Section 4:
Deploying and Operating
SBE 19plus V2 for baud rate
limitations on cable length if
transmitting real-time data.
There are two issues to consider if powering the 19plus V2 externally:
• Limiting the communication IR loss to 1 volt if transmitting real-time
data; higher IR loss will prevent the instrument from transmitting realtime data because of the difference in ground potential.
• Supplying enough power at the power source so that sufficient power is
available at the instrument after considering IR loss.
Each issue is discussed below.
Note:

The limit to cable length is typically reached when the maximum current
during communication times the power common wire resistance is more than
1 volt, because the difference in ground potential of the 19plus V2 and ground
controller prevents the 19plus V2 from transmitting real-time data.
V limit = 1 volt = IR limit
Maximum cable length = R limit / wire resistance per foot
where I = current required by SBE 19plus V2 during communication. The
current varies, depending on operating mode:
• Profiling mode – The 19plus V2 samples and transmits data continuously.
Use the total current required for sampling (sampling, pump, auxiliary
sensor current, and communication current) in the calculation.
• Moored mode – The 19plus V2 samples, and then transmits data. Use the
communication current, 65 mA, in the calculation.
Profiling Mode Examples - for 19plus V2 with standard SBE 5M pump and no auxiliary sensors
Example 1 – For 20 gauge wire, what is maximum distance to transmit power to 19plus V2 if transmitting real-time data?
Current = 70 mA (sampling) + 100 mA (pump) + 65 mA (communication) = 235 mA
R limit = V limit / I = 1 volt / 0.235 amps = 4.3 ohms
For 20 gauge wire, resistance is 0.0107 ohms/foot.
Maximum cable length = 4.3 ohms / 0.0107 ohms/foot = 402 feet = 122 meters
Example 2 – Same as above, but there are 4 instruments powered from the same power supply.
R limit = V limit / I = 1 volt / (0.235 amps * 4 instruments) = 1.1 ohms
Maximum cable length = 1.1 ohms / 0.0107 ohms/foot = 103 feet = 31 meters (to 19plus V2 furthest from power source).

Manual revision 006
Section 2: Description of SBE 19plus V2
SBE 19plus V2
Moored Mode Examples – use 65 mA communication current, regardless of 19plus V2 configuration
Example 1 – For 20 gauge wire, what is maximum distance to transmit power to 19plus V2 if transmitting real-time data?
For 65 milliamp communications current, R limit = V limit / I = 1 volt / 0.065 amps = 15.4 ohms
For 20 gauge wire, resistance is 0.0107 ohms/foot.
Maximum cable length = 15.4 ohms / 0.0107 ohms/foot = 1439 feet = 439 meters
Example 2 – Same as above, but there are 4 instruments powered from the same power supply.
For 65 milliamp communications current, R limit = V limit / I = 1 volt / (0.065 amps * 4 instruments) = 3.8 ohms
Maximum cable length = 3.8 ohms / 0.0107 ohms/foot = 355 feet = 108 meters (to 19plus V2 furthest from power source).
Supplying Enough Power to SBE 19plus V2
Another consideration in determining maximum cable length is supplying
enough power at the power source so that sufficient voltage is available, after
IR loss in the cable (from the turn-on transient, two-way resistance), to
power the 19plus V2. The table summarizes the maximum 2-way resistance
for various input supplies and pump configurations:
Power Supply Input
and Pump Configuration
3 amps at 9V input, SBE 5M pump
(cannot use SBE 5T or 5P pump with 9V input)
0.5 amps at 12V input, SBE 5M pump
3.0 amps at 12V input, SBE 5T or 5P pump
0.5 amps at 19V input, SBE 5M pump
1.5 amps at 19V input, SBE 5T or 5P pump
R limit = Maximum 2-way
Resistance (ohms)
1
10
2

7
Calculate maximum cable length as:
Maximum cable length = R limit / 2 * wire resistance per foot
Example 1 – For 20 gauge wire, what is maximum distance to transmit power to 19plus V2 if using 12 volt power source
with SBE 5T pump?
Maximum cable length = R limit / 2 * wire resistance per foot = 2 ohms / 2 * 0.0107 ohms/foot = 93 ft = 28 meters
Note that 28 meters < 173 meters and 474 meters (maximum distance if transmitting real-time data in examples above),
so IR drop in power is controlling factor for this example. Using a higher voltage power supply or a different wire gauge
would increase allowable cable length.
Example 2 – Same as above, but there are 4 instruments powered from same power supply.
Maximum cable length = R limit / 2 * wire resistance per foot * 4 instruments
= 2 ohms / 2 * 0.0107 ohms/foot * 4 = 23 ft = 7 meters (to 19plus V2 furthest from power source)

Data Storage
Note:
See Battery Endurance for
power limitations.
The SBE 19plus V2 has a 64 Mbyte FLASH memory. Shown below
are calculations of available data storage for several configurations.
See Specifications for storage space required for each parameter.
Example 1: Profiling mode, no auxiliary sensors, strain-gauge pressure
T & C = 6 bytes/sample
Strain-gauge P = 5 bytes/sample
Storage space ≈ 64,000,000 / (6 + 5) ≈ 5,818,000 samples
Example 2: Profiling mode, 6 external voltages, strain-gauge pressure
T & C = 6 bytes/sample
Strain-gauge P = 5 bytes/sample
External voltages = 2 bytes/sample * 6 voltages = 12 bytes/sample
Storage space ≈ 64,000,000 / (6 + 5 + 12) ≈ 2,782,000 samples
Example 3: Moored mode (stores date and time), 6 external voltages, strain-gauge pressure, SBE 38 RS-232 sensor
T & C = 6 bytes/sample
Strain-gauge P = 5 bytes/sample
SBE 38 = 3 bytes/sample
External voltages = 2 bytes/sample * 6 voltages = 12 bytes/sample
Date/Time = 4 bytes/sample
Storage space ≈ 64,000,000 / (6 + 5 + 12 + 3 + 4) ≈ 2,133,000 samples
Data I/O
The SBE 19plus V2 receives setup instructions and outputs diagnostic
information or previously recorded data via a three-wire RS-232C link, and is
factory-configured for 9600 baud, 8 data bits, 1 stop bit, and no parity.
19plus V2 RS-232 levels are directly compatible with standard serial interface
cards (IBM Asynchronous Communications Adapter or equal). The
communications baud rate can be changed using BaudRate= (see Command
Descriptions in Section 4: Deploying and Operating SBE 19plus V2).
Magnetic Reed Switch

end cap
Notes:
• See Command Descriptions in
Section 4: Deploying and
Operating SBE 19plus V2.
• Leave the switch in the Off
position if IgnoreSwitch=Y or
AutoRun=Y, or in Moored mode. If
the switch is On, the 19plus V2
draws an additional 15 µA from the
battery while in quiescent state.
Profiling Mode
A magnetic switch, mounted on the conductivity cell guard, can be used to
start and stop logging in Profiling mode. Sliding the switch to the On position
wakes up the SBE 19plus V2 and starts logging. Sliding the switch to the Off
position stops logging. The switch should be Off (towards the sensor end cap)
when not logging data; i.e., during setup, diagnostics, and data extraction.
The 19plus V2 can be set up to ignore the switch position:
• If IgnoreSwitch=Y: logging is started and stopped with
commands sent through the terminal program. Switch position has no
effect on logging.
• If AutoRun=Y: logging is started and stopped when external power is
applied and removed. Switch position has no effect on logging.
Moored Mode
In Moored mode, the magnetic switch position has no effect on logging.
Logging is started and stopped with commands sent through the
terminal program.

Section 2: Description of SBE 19plus V2
SBE 19plus V2
Configuration Options and Plumbing
Note:
See Section 4: Deploying and
Operating SBE 19plus V2 for
pump setup and operation.
The standard SBE 19plus V2 includes an externally mounted SBE 5M pump,
which provides a constant flow rate through the conductivity cell regardless of
descent rate. If configured with a dissolved oxygen sensor or pumped
fluorometer, the more powerful SBE 5T (titanium) or 5P (plastic) pump is used.
Any of these pumps is powered via a cable connected to the 2-pin leg of the Ycable (which is connected to the Data I/O, Pump, and External Power bulkhead
connector on the sensor end cap).
The 19plus V2 can be configured with a wide range of auxiliary sensors.
Three standard 6-pin bulkhead connectors on the sensor end cap serve as the
input ports for the auxiliary sensor signal voltages and provide power to the
sensors.
Additionally, a standard 4-pin bulkhead connector on the sensor end cap is
provided for interfacing with one of the following RS-232 sensors:
• SBE 38 secondary temperature sensor
• WET Labs sensor - single, dual, or triple channel ECO sensor; WETStar;
or C-Star
• Pro-Oceanus Gas Tension Devices (up to two GTDs can be integrated)
• Aanderaa Optode 4330 or 4835
A 19plus V2 is typically deployed in a vertical position. However, when used
with an SBE 32 (full size) Carousel Water Sampler, the 19plus V2 is deployed
in a horizontal position in an extension stand below the Carousel. Pump
placement and plumbing for a horizontal mount is different than that for a
vertical mount.
Sea-Bird provides the system with pump placement and plumbing for the
desired orientation at the time of purchase. However, you may reorient the
system later as needed. Failure to place the pump and plumbing properly can
trap air, preventing the pump from working properly.
Shown below are schematics of the system configuration for vertical and
horizontal deployment. In the schematics, cables are omitted for clarity.
Secure each tubing connection with 2 cable ties.
Vertical Mount
•
Place the exhaust as far from the intake as possible, so that exhaust water
is not pulled into the intake. Failure to place the exhaust away from the
intake can lead to errors in temperature data, because the pump transfers
heat to the exhaust water.

This section describes software installation and the pre-check procedure for
preparing the SBE 19plus V2 for deployment. The power and communications
test will verify that the system works, prior to deployment.
Software Installation
Notes:
• Help files provide detailed
information on the software.
Separate software manuals on the
CD-ROM contain detailed
information on Seasave V7 and SBE
Data Processing.
• Sea-Bird also supplies an older
version of Seasave, SeasaveWin32. However, Seasave-Win32 is
not compatible with the 19plus V2.
• It is possible to use the 19plus V2
without the SeatermV2 terminal
program by sending direct
commands from a dumb terminal or
terminal emulator, such as Windows
HyperTerminal.
• Sea-Bird supplies the current
version of our software when you
purchase an instrument. As software
revisions occur, we post the revised
software on our FTP site. See our
website (www.seabird.com) for the
latest software version number, a
description of the software changes,
and instructions for downloading the
software from the FTP site.
Sea-Bird recommends the following minimum system requirements for
installing the software: Windows 2000 or later, 500 MHz processor,
256 MB RAM, and 90 MB free disk space for installation. Although
SEASOFT V2 was designed to work with a PC running Win 2000/XP;
extensive testing has not shown any compatibility problems when using the
software with a PC running Windows Vista.
If not already installed, install Sea-Bird software programs on your computer

If this is the first time Seaterm232 is being used, the Serial Port
Configuration dialog box displays:
Computer COM port and baud
rate for communication between
computer and 19plus V2.
Seaterm232 tries to connect at
this baud rate, but if
unsuccessful will cycle through
all available baud rates.
Make the desired selections, and click OK.
4.
Note:
Seaterm232’s baud rate must be the
same as the 19plus V2 baud rate (set
with BaudRate=). Baud is factory-set
to 9600, but can be changed by the
user (see Command Descriptions in
Section 4: Deploying and
Operating SBE 19plus V2). Other
communication parameters –
8 data bits, 1 stop bit, and no parity –
cannot be changed.
Note:
If OutputExecutedTag=Y, the 19plus
V2 does not provide an S> prompt
after the <Executed/> tag at the
end of a command response.
Seaterm232 tries to automatically connect to the 19plus V2. As it
connects, it sends GetHD and displays the response, which provides
factory-set data such as instrument type, serial number, and firmware
version. Seaterm232 also fills the Send Commands window with
the correct list of commands for your 19plus V2.
If there is no communication:
A. In the Communications menu, select Configure. The Serial Port
Configuration dialog box appears. Select the Comm port and baud
rate for communication, and click OK. Note that the factory-set baud
rate is documented on the Configuration Sheet.
B. In the Communications menu, select Connect (if Connect is grayed
out, select Disconnect and reconnect). Seaterm232 will attempt to
connect at the baud specified in Step A, but if unsuccessful will then
cycle through all other available baud rates.
C. If there is still no communication, check cabling between the
computer and 19plus V2, and try to connect again.
D. If there is still no communication, repeat Step A with a different
comm port, and try to connect again.
After Seaterm232 displays the GetHD response, it provides an S> prompt
to indicate it is ready for the next command.

Notes:
• The 19plus V2 automatically enters
quiescent (sleep) state after
2 minutes without receiving a
command. This timeout algorithm is
designed to conserve battery energy
if the user does not send QS to
put the 19plus V2 to sleep.
If the system does not appear to
respond, click Connect in the
Communications menu to
reestablish communications.
• Sending the status command
causes the pump to turn on for a
moment, so that the 19plus V2 can
measure and output the pump
current. Because the pump is
designed to be water lubricated, you
may hear a noise when the impeller
spins in air. Running the pump dry
for short periods (for example, when
sending the status command) will
not harm the pump.

where
23.7658 = temperature in degrees Celsius
0.00019 = conductivity in S/m
0.062 = pressure in db
0.5632 = voltage for auxiliary sensor channel 0
2.3748 = voltage for auxiliary sensor channel 1
These numbers should be reasonable; e.g., room temperature, zero
conductivity, barometric pressure (gauge pressure).

SBE 19plus V2
Pump Operation - General
Do not run the pump dry. The pump is water lubricated; running it without
water will damage it. If briefly testing your system in dry conditions, fill the
inside of the pump head with water via the pump exhaust port. This will
provide enough lubrication to prevent pump damage during brief testing.
Pump Operation - Profiling Mode
Note:
The air bleed valve is used only when
the 19plus V2 is deployed in a vertical
orientation, as shown below. For
horizontal orientation, ensure that the
cell inlet and pump outlet remain below
the surface for PumpDelay=; see
horizontal schematic in Configuration
Options and Plumbing in Section 2:
Description of SBE 19plus V2.
After the conductivity cell enters the water, there is a user-programmable
delay before pump turn-on so that all the air in the pump tubing can escape. If
the pump motor turns on when there is air in the impeller housing, priming is
uncertain and a proper flow rate cannot be ensured. The tubing extending
above the air-bleed hole will contain a small reserve of water. This maintains
the pump prime (for up to 1 minute, depending on the length of tubing above
the air-bleed), even if the SBE 19plus V2 is lifted up so that the cell inlet and
pump outlet are just below the water surface. This allows beginning the actual
profile very near the top of the water. The cell inlet and pump outlet must
not come above the water surface or the prime will be lost.
•
Air bleed
valve
Pump turn-on occurs when two user-programmable conditions have been met:
•
Raw conductivity frequency exceeds the minimum conductivity
frequency (MinCondFreq=)
Set the minimum conductivity frequency for pump turn-on above the
instrument’s zero conductivity raw frequency (shown on the 19plus V2
Configuration Sheet), to prevent the pump from turning on when the
19plus V2 is in air.
 For salt water and estuarine applications:
typical value = zero conductivity raw frequency + 500 Hz
 For fresh/nearly fresh water:
typical value = zero conductivity raw frequency + 5 Hz
If the minimum conductivity frequency is too close to the zero
conductivity raw frequency, the pump may turn on when the 19plus V2 is
in air, as a result of small drifts in the electronics. Some experimentation
may be required, and in some cases it may be necessary to rely only on the
pump turn-on delay time to control the pump. If so, set a minimum
conductivity frequency lower than the zero conductivity raw frequency.
•
Pump turn-on delay time has elapsed (PumpDelay=)
Set the pump turn-on delay time to allow time for the Tygon tubing and
pump to fill with water after the 19plus V2 is submerged. Determine the
turn-on delay by immersing the 19plus V2 (switch off, not running) just
below the air-bleed hole at the top of the Tygon tubing. Measure the time
needed to completely fill the tubing (by watching for when air bubbles
stop coming our of the air bleed valve); 30 seconds is typical. Set the
delay to approximately 1.5 times longer. When actually using the 19plus
V2, be sure to soak the instrument just under the surface for at least the
time required for pump turn-on.

If prime is lost: Stop logging. Wait at least 5 seconds, then start logging,
submerge the 19plus V2 completely, and wait for the pump delay time
before beginning the profile. (Start and stop logging with the magnetic
switch, commands, or external power, depending on your setup.)
Pump turn-off occurs when the conductivity frequency drops below
MinCondFreq=.

Section 4: Deploying and Operating SBE 19plus V2
SBE 19plus V2
Pump Operation - Moored Mode
Pump operation is governed by two user-programmable parameters:
• MooredPumpMode=0, 1, or 2
The 19plus V2 can be set up to operate with no pump (0),
with the pump running for 0.5 seconds before each sample (1), or
with the pump running during each sample (2).
• DelayBeforeSampling=
The 19plus V2 can be set up to delay sampling after turning on external
voltage and RS-232 sensors. Some instruments require time to equilibrate
or stabilize after power is applied, to provide good quality data.
MooredPumpMode= and DelayBeforeSampling= interact in the operation of
the pump, as shown below. Recommendations for settings are provided on the
next page.
(> 2.5 seconds)
Note:
Sampling time includes time for instrument to warm up as well as time to actually measure parameters. The 2.5 second
sampling time is for 19plus V2 with strain-gauge pressure sensor and 1 measurement / sample (NCycles=1). See
Specifications in Section 2: Description of SBE 19plus V2 for sampling times for other setups.

Manual revision 006
Section 4: Deploying and Operating SBE 19plus V2
SBE 19plus V2
Moored Mode Pump Setting Recommendations
Sea-Bird provides the following recommendations for pump settings. Note that
longer pump times increase power usage, reducing battery endurance.
See Battery Endurance in Section 2: Description of SBE 19plus V2 for sample
battery endurance calculations.
Pump through Conductivity Cell Only
For most deployments, set MooredPumpMode=1 and
DelayBeforeSampling=0. The pump operates for 0.5 seconds before the
conductivity measurement is made, providing enough time to ventilate the cell
and bring in a new sample of water.
If the 19plus V2 is moored in an area with large thermal gradients, it may be
necessary to pump for a longer period of time, to eliminate any cell thermal
mass effects on the measurement. In this case, set MooredPumpMode=2 and
set DelayBeforeSampling= to a non-zero value, providing additional
ventilation time (allowing the conductivity cell temperature to equilibrate to
the water temperature) before taking the measurement.
Pump through Conductivity Cell and SBE 43 Dissolved Oxygen Sensor
Set MooredPumpMode=2.
Note:
See Application Note 64: SBE 43
Dissolved Oxygen Sensor –
Background Information, Deployment
Recommendations, and Cleaning and
Storage for the response time curves.
As the pump brings new water into the SBE 43 plenum, some time is required
for the sensor to equilibrate to the new oxygen level. The time required is
dependent on the sensor’s membrane thickness, and on the water temperature.
Prior to 2007, all SBE 43s were sold with a 0.5 mil thick membrane.
Beginning in 2007, Sea-Bird began offering two membrane thicknesses –
0.5 mil (faster response, typically for profiling applications) and
1.0 mil (slower response but more durable, typically for moored applications).
• For a 0.5 mil thick membrane – Recommended DelayBeforeSampling=
varies in a non-linear fashion, from 15 seconds at 15 °C to 30 seconds at
0 °C.
• For a 1.0 mil thick membrane – Recommended DelayBeforeSampling=
varies in a non-linear fashion, from 25 seconds at 15 °C to 40 seconds at
0 °C.
Pump through Conductivity Cell and Beckman- or YSI-type
Dissolved Oxygen Sensor
Set MooredPumpMode=2. Set DelayBeforeSampling= to
120 to 180 seconds, allowing time for the oxygen sensor to polarize before
taking the measurement.

Real-Time Setup
Notes:
• See External Power in Section 2:
Description of SBE 19plus V2 for
cable wiring on the ship.
• Set baud rate with BaudRate=.
• Set data storage and real-time
output rate with NAvg= (for Profiling
Mode) or SampleInterval=
(for Moored Mode).
• Include auxiliary A/D sensors in the
data stream with VoltN= commands.
Include auxiliary RS-232 sensors in
the data stream with SBE38=,
GTD=, or DualGTD= commands.
• Set output format with
OutputFormat=.
• Real-time data is automatically
output in Profiling Mode.
In Moored Mode, set
MooredTxRealTime=Y
to output real-time data.
• If using external power, see External
Power in Section 2: Description of
SBE 19plus V2 for power limitations
on cable length.
Baud Rate and Cable Length
Without a Sea-Bird Deck Unit
The rate that real-time data can be transmitted from the SBE 19plus V2
is dependent on the amount of data to be transmitted per scan and the serial
data baud rate:
Time required to transmit data =
(number of characters * 10 bits/character) / baud rate
where
Number of characters is dependent on the included data and output
format (see Data Output Formats).
Add 2 to the number of characters shown in the output format, to
account for the carriage return and line feed at the end of each scan.
For decimal output (OutputFormat=2, 3, or 5), include decimal
points, commas, and spaces when counting the number of characters.
In Profiling Mode, the time required to transmit data must be less than the
real-time output rate. In Moored Mode, the time required to transmit data plus
the time required to make the measurements must be less than the
(interval between samples – 5 seconds) for Autonomous Sampling, because
the 19plus V2 goes to sleep for a minimum of 5 seconds between each sample.
The length of cable that the 19plus V2 can drive is also dependent on the baud
rate. The allowable combinations are:
400
200
100
50
25
Maximum Cable 1600 800
Length (meters)
600
1200 2400 4800 9600 19200 38400
Maximum
Baud Rate
Example 1 - 19plus V2 without a Deck Unit. Profiling Mode, strain-gauge pressure, configured with 2 external voltages.
What is the fastest rate you can transmit real-time data over 800 m with OutputFormat=0 (raw hexadecimal data)?
With 800 meters of cable and no Deck Unit, the 19plus V2 requires a baud rate of 1200 or less.
Number of characters for OutputFormat=0 (from Data Output Formats) =
6 (T) + 6 (C) + 6 (P) + 4 (P temperature compensation) + 2*4 (external voltages) + 2 (carriage return & line feed) = 32
Time required to transmit data = (32 characters * 10 bits/character) / 1200 =
0.267 seconds > 0.25 seconds (4 Hz, maximum sampling rate).
Therefore, set NAvg=2, averaging 2 measurements/sample and storing and transmitting 1 sample every 0.5 seconds.
Example 2 - 19plus V2 without a Deck Unit. Moored Mode, strain-gauge pressure, configured with 4 external voltages,
10 measurements/sample (NCycles=10), pump running during sampling (MooredPumpMode=2), and a 15-second
delay before sampling (DelayBeforeSampling=15). What is the smallest sample interval you can use if you want to
transmit real-time data over 800 m with OutputFormat=0 (raw hexadecimal data)?
With 800 meters of cable, the 19plus V2 requires a baud rate of 1200 or less.
Number of characters for OutputFormat=0 (from Data Output Formats) =
6 (T) + 6 (C) + 6 (P) + 4 (P temperature compensation) + 4*4 (external voltages) + 8 (time) + 2 (carriage return & line feed) = 48
Time required to transmit data = (48 characters * 10 bits/character) / 1200 = 0.4 seconds
Minimum time required for each sample =
15 seconds (delay after turning on power) + 2.5 second sampling time + [(10-1) * 0.25 seconds] +
0.4 seconds to transmit real-time + 5 seconds to go to sleep between samples = 25.15 seconds, round up to 27
Therefore, set SampleInterval=27, storing and transmitting one sample every 27 seconds.

Manual revision 006
Section 4: Deploying and Operating SBE 19plus V2
SBE 19plus V2
With a Sea-Bird Deck Unit
Set the 19plus V2 baud rate to 4800 if using the 19plus V2 with either of the
following real-time data acquisition systems:
•
SBE 36 CTD Deck Unit and Power and Data Interface Module (PDIM)
•
SBE 33 Carousel Deck Unit and SBE 32 Carousel Water Sampler OR
SBE 33 Carousel Deck Unit and SBE 55 ECO Water Sampler
The data telemetry link can drive 10,000 meters of cable while accepting
4800 baud serial data. The relationship between transmission rate, amount of
data transmitted, and baud rate is as described above for a 19plus V2 without a
Deck Unit.
Example - 19plus V2 with an SBE 33 or 36 Deck Unit. Profiling Mode, strain-gauge pressure, configured with 2 external
voltages. What is the fastest rate you can transmit data with OutputFormat=0 (raw hexadecimal data)?
With a Deck Unit, the 19plus V2 requires a baud rate of 4800.
Number of characters (from Data Output Formats) =
6 (T) + 6 (C) + 6 (P) + 4 (P temperature compensation) + 2*4 (external voltages) + 2 (carriage return & line feed) = 32
Time required to transmit data = (32 characters * 10 bits/character) / 4800 =
0.067 seconds < 0.25 seconds (4 Hz, maximum sampling rate).
Therefore, set NAvg=1, providing 4 Hz data (one sample every 0.25 seconds) for this configuration.
Real-Time Data Acquisition
Note:
If the FLASH memory is filled to
capacity, data sampling and
transmission of real-time data (if
programmed) continue, but excess
data is not saved in memory.
Real-time data can be acquired in either of the following ways:
•
With Seasave (typical method) – When the 19plus V2 is set up for
Profiling Mode or Autonomous Sampling Moored Mode, data can be
viewed in Seasave in tabular form or as plots, as raw data or as converted
(engineering units) data. Data acquired with Seasave can be processed
with SBE Data Processing. See Seasave’s Help files for details on setting
up the program displays, baud rates, etc., and beginning data acquisition.
•
With Seaterm232 – Click the Capture menu; enter the desired file name in
the dialog box, and click Save. Begin logging. The data displayed in
Seaterm232 will be saved to the designated file. Process the data as
desired. Note that this file cannot be processed by SBE Data Processing
or displayed in Seasave, as it does not have the required headers and
format for Sea-Bird’s processing software.
Timeout Description
The SBE 19plus V2 has a timeout algorithm. If the 19plus V2 does not receive
a command or sample data for 2 minutes, it powers down its main digital
circuits. This places the 19plus V2 in quiescent state, drawing minimal current.
To re-establish control (wake up), click Connect in Seaterm232’s
Communications menu or press the Enter key.

When entering commands:
•
•
•
•
•
•
•
•
•
Note:
In Profiling mode, the 19plus V2 does
not respond to TS, SL, SLT, or
GetLastSamples:x while logging or
waiting to start logging.
•
Input commands to the 19plus V2 in upper or lower case letters and
register commands by pressing the Enter key.
The 19plus V2 sends an error message if an invalid command is entered.
(if OutputExecutedTag=N) If the 19plus V2 does not return an
S> prompt after executing a command, press the Enter key to get the
S> prompt.
If a new command is not received within 2 minutes after the completion
of a command, the 19plus V2 returns to the quiescent (sleep) state.
If in quiescent state, re-establish communications by selecting Connect in
Seaterm232’s Communications menu or pressing the Enter key.
If the 19plus V2 is transmitting data and you want to stop it, press the
Esc key or type ^C. Then press the Enter key. Alternatively, select Abort
in Seaterm232’s Command menu.
Commands to enable a parameter or output (such as enabling a voltage
channel) can be entered with the argument as Y or 1 for yes, and N or 0
for no (for example, Volt0=y and Volt0=1 are equivalent; both enable
voltage channel 0).
The 19plus V2 cannot have samples with different scan lengths (more or
fewer data fields per sample) in memory. If the scan length is changed by
commanding it to add or subtract a data field (such as an external voltage),
the 19plus V2 must initialize logging. Initializing logging sets the sample
number and cast number to 0, so the entire memory is available for
recording data with the new scan length. Initializing logging should only
be performed after all previous data has been uploaded. Therefore,
commands that change the scan length (MM, MP, PType=, Volt0=,
Volt1=, Volt2=, Volt3=, Volt4=, Volt5=, SBE38=, GTD=, DualGTD=,
Optode=) prompt the user for verification before executing, to prevent
accidental overwriting of existing data.
The 19plus V2 responds only to GetCD, GetSD, GetCC, GetEC,
ResetEC, GetHD, DS, DCal, TS, SL, SLT, GetLastSamples:x, QS, and
Stop while logging. If you wake the 19plus V2 while it is logging (for
example, to send DS to check on logging progress), it temporarily stops
logging. In Moored mode, logging resumes when it goes to sleep (either
by sending QS or after the 2-minute timeout). In Profiling mode, logging
resumes immediately.
The 19plus V2 responds only to GetCD, GetSD, GetCC, GetEC,
ResetEC, GetHD, DS, DCal, TS, SL, SLT, GetLastSamples:x, QS, and
Stop while waiting to start logging (if you sent StartLater but logging
has not started yet). To send any other commands, send Stop, send the
desired commands to modify the setup, and then send StartLater again.
Entries made with the commands are permanently stored in the 19plus V2 and
remain in effect until you change them.
•
The only exception occurs if the electronics are removed from the housing
and disconnected from the battery Molex connector (see Appendix II:
Electronics Disassembly/Reassembly). Upon reassembly, reset the date
and time (DateTime=) and initialize logging (InitLogging).

Section 4: Deploying and Operating SBE 19plus V2
Notes:
• The DS response contains similar
information as the combined
responses from GetSD and GetCD,
but in a different format.
• Sending GetSD causes the pump to
turn on for a moment, so that the
19plus V2 can measure and output
the pump current. Because the
pump is designed to be water
lubricated, you will hear a noise
when the impeller spins in air.
Running the pump dry for such a
short time will not harm the pump.
• In the example below, only voltage
channel 0 is enabled, so external
voltage current iext2345= (for
channels 2, 3, 4, and 5) is not
shown.
• In the example below, no RS-232
sensor is enabled, so RS-232
sensor current iserial= is not shown.
• If the 19plus V2 is set up with a WET
Labs ECO-FL fluorometer with
Bio-Wiper (Biowiper=Y) and if
OutputExecutedTag=Y, the GetSD
response shows: <Executing/>
to allow time for the Bio-Wiper to
close before it measures the
enabled external voltage currents.

Get and display event counter data, which
can help to identify root cause of a
malfunction. Event counter records
number of occurrences of common
timeouts, power-on resets, etc. Can be
cleared with ResetEC. Possible events that
may be logged include:
• Power fail – main batteries and/or external
voltage below voltage cutoff
• EEPROM read or EEPROM write – all
power removed (main batteries removed, and
back-up lithium batteries are dead)
• Alarm short – woke up 19plus V2 to send a
command while logging in Moored mode
• Alarm long –sent StartLater, but
StartDateTime= is more than 1 month in
future
• AD7730 timeout – response from
temperature and pressure A/D converter
delayed; typically if woke up to send a
command while logging in Moored mode
• AD7714 timeout – response from voltage
channel A/D converter delayed; typically if
woke up to send a command while logging
in Moored mode
• FLASH out of memory – all available
memory space is used; autonomous sampling
continues, but no additional data written to
FLASH (does not overwrite)
• FLASH correctable error – single bit error in
a page, corrects itself, does not affect data
• FLASH ECC error – does not affect data
• FLASH timeout – problem with FLASH
• FLASH ready – problem with FLASH;
timeout error
• FLASH erase failed – problem with FLASH
• FLASH write failed – problem with FLASH
• FLASH uncorrectable – problem with
FLASH; 2 or more bits of errors in a page
• FLASH block overrun – problem with

SBE 19plus V2
General Setup Commands
DateTime=mmddyyyyhhmmss
Set real-time clock month, day, year, hour,
minute, second.
Example: Set current date and time to 05 August 2011 12:05:00 (user input in bold).
datetime=08052011120500
Notes:
• The 19plus V2 baud rate (set with
BaudRate=) must be the same as
Seaterm232’s baud rate (set in the
Communications menu).
• An RS-232 sensor (SBE 38, WET
Labs sensor, GTD, or Optode)
integrated with the 19plus V2 must
use the same baud rate as the
19plus V2. See the RS-232 sensor’s
manual to set its baud. Note that the
Optode only communicates at 9600
baud, so you must set the 19plus V2
baud to 9600 if interfacing with that
sensor.
• BaudRate= must be sent twice.
After the first entry, the 19plus V2
changes to the new baud, and then
waits for the command to be sent
again at the new baud (In the
Communications menu, select
Configure. In the dialog box, select
the new baud rate and click OK.
Then retype the command.). This
prevents you from accidentally
changing to a baud that is not
supported by your computer. If it
does not receive the command
again at the new baud, it reverts to
the previous baud rate.
BaudRate=x
x= baud rate (600, 1200, 2400, 4800,
9600, 19200, 38400, 57600, or 115200).
Default 9600. Check capability of your
computer and terminal program before
increasing baud rate. Command must be
sent twice to change rate.
Echo=x
x=Y: Echo characters received from
computer (default) - monitor will show
entered commands as you type.
x=N: Do not.
OutputExecutedTag=x
x=Y: Display XML Executing and
Executed tags (default). Executed tag
displays at end of each command
response; Executing tag displays one or
more times if 19plus V2 response to a
command requires additional time.
x=N: Do not.
Example: Set 19plus V2 to output Executed and Executing tags (user input in bold).
outputexecutedtag=y
<Executed/>getcd
. . .
(GetCD response)
<Executed/>
(Note: <Executed/> tag at end of command response takes place of S> prompt.)
BatteryType=x
x=alkaline: Alkaline batteries (also use
this setting for lithium batteries). Logging
stops when voltage drops below 7.5 volts
for 5 consecutive scans. This reduces
battery load to quiescent current.
x=nicad: Ni-Cad batteries (as of 2011, no
longer available). Logging stops when
voltage drops below 7.5 volts for
5 consecutive scans or voltage is less than
10.9 volts and voltage drop is greater than
0.5 volts/minute as determined by two
30-second moving averages. This reduces
battery load to quiescent current once first
cell in battery pack is exhausted.
x=nimh: NiMH batteries. Logging stops
when voltage drops below 7.8 volts for
5 consecutive scans or voltage is less than
8.7 volts and voltage drop is greater than
0.2 volts/minute as determined by two 30second moving averages. This reduces
battery load to quiescent current once first
cell in battery pack is exhausted.

Section 4: Deploying and Operating SBE 19plus V2
Notes:
• The 19plus V2 requires verification
when InitLogging,
SampleNumber=, or
HeaderNumber= are sent.
19plus V2 responds:
General Setup Commands (continued)
InitLogging
Initialize logging - after all previous data
has been uploaded, initialize logging
before starting to sample again to make
entire memory available for recording.
InitLogging sets sample number
(SampleNumber=) and header and cast
number (HeaderNumber=) to 0
(sampling will start with sample 1 and
cast/header 1). If not set to 0, data will be
stored after last recorded sample. Do not
send InitLogging until all existing data
has been uploaded.
SampleNumber=x
x= sample number for last sample in
memory. Typically only used to recover
data if you accidentally initialize logging
(using InitLogging) before uploading all
existing data. Do not send
SampleNumber=0 until all existing data
has been uploaded.
HeaderNumber=x
x= header and cast number for last cast or
header in memory. Typically used to
recover data if you accidentally initialize
logging (using InitLogging or
SampleNumber=0) before uploading all
existing data. 19plus V2 can have a
maximum of 1000 stored headers.
Note that 19plus V2 writes a new header:
- each time logging is started in
Profiling Mode
- each time logging is started and after
every 2000 samples are stored in memory
in Moored Mode.
Biowiper=x
x=Y: Configuration includes WET Labs
ECO-FL fluorometer with Bio-Wiper
(voltage or RS-232 auxiliary sensor). With
this setup, 19plus V2 is powered longer for
DS and GetSD, providing sufficient time
for Bio-Wiper to open and then shut again
if in Moored mode if Bio-Wiper is set up
to take 1 measurement for each sample
(see Application Note 72).
this command will change the
scan length and/or initialize
logging. Repeat the command to
verify.
Type the command again and press
the Enter key to proceed. The
19plus V2 responds:
Scan length has changed,
initializing logging
• Do not initialize logging until all
data has been uploaded. These
commands do not delete data; they
reset the data pointer. If you
accidentally initialize logging
before uploading, recover data as
follows:
1. Set SampleNumber=a and
HeaderNumber=b, where a and b are
your estimate of number of samples
and casts in memory.
2. Upload data. If a is more than actual
number of samples or b is more than
actual number of casts in memory,
data for non-existent samples/casts
will be bad, random data. Review
uploaded data file carefully and delete
any bad data.
3. If desired, increase a and/or b and
upload data again, to see if there is
additional valid data in memory.
Note:
If an ECO-FL with Bio-Wiper is
installed and Biowiper=N, sending
GetSD or DS will open the Bio-Wiper,
but not provide enough powered time
to close it again. If you then deploy the
instrument in Moored mode (MM) with
the Bio-Wiper open and with a delayed
start time, the ECO-FL may become
fouled because the Bio-Wiper will
remain open until the first sample is
completed.
Note:
The 19plus V2 automatically enters
quiescent (sleep) state after 2 minutes
without receiving a command,
conserving battery energy if the user
does not send QS to put the 19plus V2
to sleep.
SBE 19plus V2
x=N (default): No ECO-FL with
Bio-Wiper.
QS
Quit session and place 19plus V2 in
quiescent (sleep) state. Main power turned
off. Data logging and memory retention not
affected.

uploaded data. View and edit the
configuration file in Seasave or SBE
Data Processing. These parameters
are factory-set to match the ordered
instrument configuration.
• External voltage numbers 0, 1, 2, 3,
4, and 5 correspond to wiring of
sensors to a voltage channel on the
19plus V2 end cap (see Dimensions
and End Cap Connectors in Section
2: Description of SBE 19plus V2).
However, in the .xmlcon or .con file,
voltage 0 is the first external voltage
in the data stream, voltage 1 is the

• The 19plus V2 configuration
(.xmlcon or .con) file must match this
selection of RS-232 sensor when
viewing real-time data or processing
uploaded data. View and edit the
configuration file in Seasave or SBE
Data Processing. These parameters
are factory-set to match the ordered
instrument configuration.
• You can use Seaterm232 to
communicate directly with the
SBE 38 (when the sensor is
connected directly to the computer).
Alternatively, use the older
SEATERM software, as documented
in the manual for the SBE 38.
• See the appropriate sensor manual
for command details for the RS-232
instruments.
The SBE 19plus V2 can interface with one of the following RS-232
instruments (connected to the 4-pin Auxiliary RS-232 Input bulkhead
connector on the 19plus V2 end cap):
• SBE 38 secondary temperature sensor
• WET Labs single, dual, or triple channel ECO sensor; WETStar; or C-Star
• Pro-Oceanus Gas Tension Devices (up to two GTDs can be integrated)
• Aanderaa Oxygen Optode 4330 or 4835
Setup for SBE 38:
Set up SBE 38 to interface with SBE 19plus V2, before you connect it to
19plus V2. Connect SBE 38 directly to computer, power with an external
power supply, and (using SEATERM or Seaterm232) set:
• Baud rate to same baud rate as 19plus V2 (Baud=)
• Interface to RS-232 (Interface=232)
• Sampling to begin when power applied (AutoRun=Y)
• Output to converted data (Format=C)
Connect SBE 38 to SBE 19plus V2 Auxiliary RS-232 Input connector, using
provided cable. In the 19plus V2, set SBE38=Y to enable interface.

RS-232 Sensor Setup Commands (continued)
Note:
In Moored mode, the 19plus V2
sample interval (SampleInterval=)
must be greater than or equal to the
sum of the times required to sample.
Total time is affected by the following:
- Minimum time required for 19plus V2
to take a sample (≈ 2.5 sec).
- Time required for 19plus V2 to take
and average NCycles= samples;
samples are taken 0.25 sec apart.
- Delay after providing power to
external sensors before sampling
(DelayBeforeSampling=); minimum
DelayBeforeSampling= is 2 sec if
using a WET Labs RS-232 sensor.
- Time required to run pump before
sampling (0.5 sec if
MooredPumpMode=1).
Setup for WET Labs Sensor
(single, dual, or triple ECO Sensor; WETStar, or C-Star):
• 19plus V2 must be set to 19200 baud (BaudRate=19200) if interfacing
with a WET Labs RS-232 sensor.
• If in Moored mode: 19plus V2 DelayBeforeSampling= must be > 2 sec if
using a WET Labs RS-232 sensor. If WetLabs=Y and
DelayBeforeSampling < 2 sec, 19plus V2 automatically sets
DelayBeforeSampling=2.
Note that the SBE 19plus V2 stores and outputs 6 bytes of WET Labs RS-232
data for each sample, with 2 bytes for each channel. If integrating an ECO
Triplet, each sensor of the Triplet uses 2 bytes (for a total of 6 bytes). If
integrating a dual ECO sensor (such as the FLNTU), the first 4 bytes contain
the sensor data; the remaining 2 bytes are 0’s. For single WET Labs RS-232
sensors, the first 2 bytes contain the sensor data; the remaining 4 bytes are 0’s.
WetLabs=x
x=Y: Enable WET Labs RS-232 sensor.

SBE 19plus V2
RS-232 Sensor Setup Commands (continued)
Setup for GTD:
SBE 19plus V2 must be in Moored mode (MM) to obtain GTD data. Set up
GTD to interface with 19plus V2, before you connect it to 19plus V2. Connect
GTD directly to computer, power with an external power supply, and (using
software provided by Pro-Oceanus) set:
• Baud rate to same baud rate as 19plus V2.
• Output to millibars.
• Sum of pressure integration time and temperature integration time so
that GTD responds to a take pressure reading command in 40 seconds or
less (required so that 19plus V2 does not time out while waiting for reply).
Connect GTD to 19plus V2 Auxiliary RS-232 Input connector, using provided
cable (end labeled Pro-Oceanus to GTD; end labeled Sea-Bird to 19plus V2).
In the 19plus V2, set:
• GTD=Y or DualGTD=Y to enable interface.
• SendGTD= to change IDs if necessary.
The 19plus V2 samples the GTD last, after DelayBeforeSampling=, and after
conductivity, temperature, and pressure, and all voltage channels have been
sampled. To conserve power, the voltage to any other external sensors and the
pump are turned off before acquiring the GTD sample.
Each time a sample is to be taken, 19plus V2 sends following commands to
GTD (ID= 01, 02, etc.):

RS-232 Sensor Setup Commands (continued)
Setup for Aanderaa Optode:
19plus V2 must be set to 9600 baud (BaudRate=9600) if interfacing with an
Optode.
Notes:
• When setting up the configuration
(.xmlcon or .con) file In Seasave
and/or SBE Data Processing, select
Oxygen, Optode for the Serial RS232C sensor. Enter the serial
number, calibration date, and
information required for salinity and
depth corrections. The internal
salinity must match the value you
programmed into the Optode (the
value is ignored if you do not enable
the Salinity correction). If you enable
Salinity correction, our software
corrects the oxygen output from the
Optode based on the actual salinity
(calculated from the CTD data). If
you enable Depth correction, our
software corrects the oxygen output
from the Optode based on the depth
(calculated from the CTD data).
• You must send do stop to the
Optode to interrupt oxygen sampling
before sending commands with
SendOptode=. You may need to
send the stop command several
times.
• (Moored Mode) Power turn-on
defined by DelayBeforeSampling=
does not apply to the RS-232
Aanderaa Optode, because turning
on power to the Optode causes it to
sample. The 19plus V2 turns on
power to the Optode when the
19plus V2 is ready to acquire the
Optode data, after all CTD and other
external sensor data is acquired.
Set up Optode to interface with 19plus V2, before you connect it to
19plus V2. Connect Optode directly to computer, power with an external
power supply, and (following directions provided by Aanderaa) set:
• Communication to RS-232.
• Sample interval to 1 for Profiling mode, or 5 for Moored mode.
Note that the Optode samples at a maximum of 1 Hz (1 sample/sec).
In Profiling mode, 19plus V2 samples at 4 Hz; therefore, Optode output in
19plus V2 data stream will only change after every 4 scans.
• Output to model number, serial number, and oxygen concentration
(micromoles/liter) in decimal format. Disable all other output (air
saturation, temperature, raw data, and text).
Connect Optode to SBE 19plus V2 Auxiliary RS-232 Input connector.
In 19plus V2, set Optode=Y to enable interface.
Optode=x
x=Y: Enable RS-232 Optode.
x=N: Do not enable Optode.
SendOptode=command
Command 19plus V2 to send command to
Optode and receive response; command
can be any command recognized by
Optode (see Optode manual). Reply from
Optode is limited to one line.
Example: Send stop command to Optode to interrupt sampling, and then sample

Output Format Setup Commands
See Data Output Formats after the command descriptions for complete details
on all the formats.
Note:
Output format does not affect how
data is stored in FLASH memory.
Sea-Bird’s real-time data acquisition
(Seasave) and data processing
(SBE Data Processing) software
require data in raw hexadecimal
(OutputFormat=0).
Typical use of the output format
command is:
• Before beginning logging:
 If you will use Seasave to view
real-time data - Set output format
to raw hex.
 If you will use Seaterm232 to
view real-time data - Set output
format to converted decimal for
ease in viewing real-time data.
• After stopping sampling, use
Seaterm232’s Upload menu to
upload data from memory. This
automatically uploads the data in
raw hex (regardless of the
OutputFormat= setting), so the
uploaded data is compatible with
SBE Data Processing for processing
and with Seasave for viewing
archived data.
OutputFormat=x
x=0: Output raw frequencies and voltages
in hexadecimal. Must use this format for
acquiring and viewing real-time data in
Seasave. When using Seaterm232’s
Upload menu, Seaterm232 always uploads
data from memory in raw hex (compatible
with SBE Data Processing), regardless of
user-programmed OutputFormat=.
x=1: Output converted (engineering units)
data in hexadecimal.
x=2: Output raw frequencies and voltages
in decimal.
x=3: Output converted (engineering units)
data in decimal.
x=4: Output pressure and scan number
only, in hexadecimal. Typically used only
for interfacing with Auto Fire Module
(AFM) and SBE 32 Carousel Water
Sampler or with SBE 55 ECO Water
Sampler (for autonomous water sampling).
x=5: Output converted (engineering units)
data in decimal, in XML.
OutputSal=x
x=Y: Calculate and output salinity (psu).
Only applies if OutputFormat=3 or 5.
x=N: Do not.
OutputSV=x
x=Y: Calculate and output sound velocity
(m/sec), using Chen and Millero formula
(UNESCO Technical Papers in Marine
Science #44). Only applies if
OutputFormat=3 or 5.
x=N: Do not.
OutputUCSD=x
x=Y: Calculate and output density sigma-t
(kg/m3), battery voltage, and operating
current (mA) with data polled while
logging. Voltage and current measured
after delay before sampling, but before
sampling. Operating current measured and
output only if in Moored mode. Only
applies if OutputFormat=3 or 5.
x=N: Do not.

Section 4: Deploying and Operating SBE 19plus V2
Note:
The 19plus V2 requires verification
when MP is sent. 19plus V2 responds:
this command will change the
scan length and/or
initialize logging. Repeat
the command to verify.
Type the command again and press
the Enter key to proceed.
The 19plus V2 responds:
Scan length has changed,
initializing logging
Note:
For a 19plus V2 with optional Quartz
pressure sensor, NAvg= must be an
even number (2, 4, etc.); increasing
NAvg= reduces the measurement
noise. See Specifications in Section 2:
Description of SBE 19plus V2 to
determine resolution.
Profiling Mode Setup Commands
Profiling mode setup commands following MP apply to Profiling mode
only, and have no effect on operation if the 19plus V2 is in Moored mode.
MP
Set 19plus V2 to Profiling mode.
NAvg=x
x= number of samples to average
(default 1, maximum 32,767). 19plus V2
samples at 4 Hz (every 0.25 seconds) and
averages NAvg samples; averaged data is
stored in FLASH memory and transmitted
real-time.
Example: 19plus V2 samples every 0.25 seconds. If NAvg=2, 19plus V2
averages data from 2 samples (= 1 averaged data sample per 0.5 seconds), stores
averaged data in FLASH memory, and transmits averaged data real-time.
MinCondFreq=x
x= minimum conductivity frequency (Hz)
to enable pump turn-on, to prevent pump
from turning on before 19plus V2 is in
water. Pump stops when conductivity
frequency drops below MinCondFreq=.
19plus V2 Configuration Sheet lists
uncorrected (raw) frequency output at
0 conductivity. Typical value (and factoryset default) for MinCondFreq= for salt
water and estuarine application is:
(0 conductivity frequency + 500 Hz).
Typical value for MinCondFreq= for fresh
water applications is:
(0 conductivity frequency + 5 Hz).
PumpDelay=x
x= time (seconds) to wait after minimum
conductivity frequency (MinCondFreq=) is
reached before turning pump on. Pump
delay time allows time for Tygon tubing
and pump to fill with water after
19plus V2 is submerged.
Pump starts PumpDelay= seconds after
conductivity cell’s frequency output is
greater than MinCondFreq=.
Typical value 30 - 45 seconds; range
0 – 600 seconds. Default 60 seconds.
AutoRun=x
x=Y: Start logging automatically when
external power applied; stop logging when
external power removed. Magnetic switch
position has no effect on logging.
Note:
See Pump Operation – Profiling Mode.
Note:
To start sampling immediately after
you send AutoRun=Y (if you were
performing setup on external power):
• Send QS to put 19plus V2 in
quiescent (sleep) state, and then
turn external power off and then on
again. or
• Send StartNow.
SBE 19plus V2
x=N: Wait for command when external
power applied. Default.
IgnoreSwitch=x
Note:
If IgnoreSwitch=N: Sending Stop only
stops logging briefly, and then logging
resumes. To stop logging, slide the
magnetic switch off or send <CTRL Z>.
x=Y: Do not start or stop logging based on
position of magnetic switch. Use
StartNow, StartLater, and Stop to
control logging.
x=N: Do not ignore magnetic switch
position. Logging controlled by switch
position. Default.

NCycles=x
x= number of measurements to take and
average every SampleInterval seconds.
Range 1 – 100; default 1. 19plus V2 takes
and averages NCycles samples (each
0.25 seconds apart) each SampleInterval
seconds; averaged data is stored in FLASH
memory and (if MooredTxRealTime=Y)
transmitted real-time.

Notes:
• For 19plus V2 with optional Quartz
pressure sensor, NCycles= must be
an even number (2, 4, etc.);
increasing NCycles= reduces
measurement noise. See
Specifications in Section 2:
Description of SBE 19plus V2 to
determine resolution.
• 19plus V2 integrates for the Quartz
pressure sensor after NCycles=
measurements have been taken.
Moored mode setup commands following MM apply to Moored Mode
only, and have no effect on operation if the 19plus V2 is in Profiling mode.
Example: If SampleInterval=20 and NCycles=4, every 20 sec 19plus V2 takes 4 measurements
(0.25 sec apart), averages data from 4 measurements, and stores averaged data in FLASH memory.
MooredPumpMode=x
Notes:
• Pump operation is affected by both
DelayBeforeSampling= and
MooredPumpMode=. See Pump
Operation – Moored Mode.
• NCycles=, DelayBeforeSampling=,
MooredPumpMode=, and
MooredTxRealTime= affect the
time required to sample. If the time
required to sample is too high, the
19plus V2 is unable to take the
required number of measurements
and do the calculations within
SampleInterval=. See Sample
Timing in Section 2: Description of
SBE 19plus V2.
• Power turn-on defined by
DelayBeforeSampling= does not
apply to the RS-232 Aanderaa
Optode, because turning on power
to the Optode causes it to sample.
The 19plus V2 turns on power to the
Optode when the 19plus V2 is ready
to acquire the Optode data.
x=0: No pump.
x=1: Run pump for 0.5 seconds before
each sample (typical for pumping through
conductivity cell only, with no auxiliary
sensors connected to plumbing).
x=2: Run pump during each sample
(typical for pumping through conductivity
cell and in-line auxiliary sensor).
DelayBeforeSampling=x
x= time (seconds) to wait after switching
on external voltage and RS-232 sensors
before sampling (0-600 seconds). Default
0 seconds. Typical values if using:
- SBE 43 oxygen sensor – time is
dependent on membrane thickness and
on water temperature (see Pump
Operation – Moored Mode) . Use with
MooredPumpMode=2.
- Beckman- or YSI-type oxygen sensor –
120 to 180 seconds required to provide
time for sensor to polarize.
Use with MooredPumpMode=2.
- Sea Tech fluorometer - 15 seconds
required to provide time for sensor
to stabilize.
MooredTxRealTime=x
x=Y: Output real-time data.
x=N: Do not.

Section 4: Deploying and Operating SBE 19plus V2
Notes:
• In Seaterm232, to save real-time
data to a file, click the Capture menu
before beginning logging.
• If the FLASH memory is filled to
capacity, data sampling and
transmission of real-time data
continue, but excess data is not
saved in memory. The 19plus V2
will not overwrite data stored in
memory.
• If the 19plus V2 is sampling and the
voltage is less than the cut-off
voltage (see BatteryType= for cutoff values for various battery types),
the 19plus V2 halts logging and
displays WARNING: LOW BATTERY
VOLTAGE.
Note:
Sea-Bird ships the 19plus V2 with
AutoRun=N (it will not automatically
start sampling when external power is
applied). If you send AutoRun=Y:
• Send QS to put 19plus V2 n
quiescent (sleep) state, then turn
power off and then on again to start
sampling,
or
• Send StartNow to start sampling.
Note:
For Moored mode, the magnetic switch
should be left off, but it has no effect
on logging. If the switch is turned on
while the 19plus V2 is in quiescent
state, the CPU enters the awake state,
but logging does not begin. If no
communications are established, the
19plus V2 times out and enters
quiescent state after 2 minutes.
SBE 19plus V2
Logging Commands
Logging commands direct the SBE 19plus V2 to sample data. When
commanded to start sampling, the 19plus V2 takes samples and stores the data
in its FLASH memory. Operation is dependent on the mode and setup.
Profiling Mode (MP)
While logging, the 19plus V2 transmits real-time data, and does not enter
quiescent (sleep) state between samples. The 19plus V2 provides several
methods for starting and stopping logging, depending on the settings for
IgnoreSwitch= and AutoRun=. Logging starts approximately 1 - 2 seconds
after it is commanded.
IgnoreSwitch= AutoRun= To Start Logging:

commands to check or
modify setup) Send Stop.
The first time logging is started after receipt of the initialize logging command
(InitLogging), data recording starts at the beginning of memory and any
previously recorded data is written over. When logging is stopped, recording
stops. Each time logging is started again, recording continues, with new data
stored after the previously recorded data and a new header written to indicate
the incremented cast number, date, time, and sample numbers contained in the
cast. The maximum number of casts that can be taken is 1000.
Moored Mode (MM)
While logging, the 19plus V2 transmits real-time data if
MooredTxRealTime=Y. The 19plus V2 enters quiescent (sleep) state
between samples.
To start logging, use StartNow; logging starts SampleInterval= seconds after
receipt of StartNow. Alternatively, use StartDateTime= and StartLater to
start logging at a designated date and time. The first time logging is started
after receipt of the initialize logging command (InitLogging), data recording
starts at the beginning of memory and any previously recorded data is written
over. When Stop is sent, recording stops. Each time StartNow or StartLater
is sent again, recording continues, with new data stored after the previously
recorded data. A new header is written each time logging starts and every
2000 samples thereafter. A maximum of 1000 headers can be written; if the
maximum number of headers is reached but there is still room for samples in
FLASH memory, the 19plus V2 continues to sample and store sample data in
FLASH memory without writing additional headers.

Logging Commands (continued)
Notes:
• If using StartNow or StartLater to
start logging, the 19plus V2 must be
set to Moored mode (MM), or if in
Profiling mode (MP) must be set to
ignore the magnetic switch
(IgnoreSwitch=Y).
• After receiving StartLater, the
19plus V2 displays
waiting to
start at . . . in reply to
GetSD or DS. Once logging starts,
the DS reply displays
logging.
• If the delayed start date and time
has already passed when StartLater
is received, the 19plus V2 executes
StartNow.
• If the delayed start date and time is
more than 1 month in the future
when StartLater is received, the
19plus V2 assumes that the user
made an error in setting the delayed
start date and time, and it executes
StartNow.
Notes:
• You may need to send Stop several
times to get the 19plus V2 to
respond.
• If in Profiling mode and
IgnoreSwitch=N: Sending Stop
only stops logging briefly, and then
logging resumes. To stop logging,
slide the magnetic switch off or send
<CTRL Z>.
• You must stop logging before
uploading data.
StartNow
Start logging now.
StartDateTime=

StartLater
Set delayed logging start month, day, year,
hour, minute, and second.
Start logging at time set with
StartDateTime=. If you need to change
19plus V2 setup after StartLater has been
sent (but before logging has started), send
Stop, change setup as desired, and then
send StartLater again.
Example: Program 19plus V2 to start logging on 20 January 2010
12:05:00. (user input in bold)
STARTDATETIME=01202010120500

Polled Sampling Commands
Notes:
• The 19plus V2 has a buffer that
stores the most recent data
samples. Unlike data in the
FLASH memory, data in the
buffer is erased upon removal or
failure of power.
• Pump operation for polled
sampling is defined by
MooredPumpMode=, even if
your 19plus V2 is set to Profiling
Mode (MP). Thus, the 19plus V2
ignores the minimum conductivity
frequency (MinCondFreq=) and
pump delay (PumpDelay=) for
polled sampling.
• Leave power on in SL, SLT, TS,
and TSSOn descriptions refers to
power for the 19plus V2 as well
as for the pump and any auxiliary
sensors. Power remains on until
QS is sent or the instrument
times out (after 2 minutes).
These commands request a single sample. The 19plus V2 always stores data
for the most recent sample in its buffer. Some polled sampling commands also
store data in FLASH memory - the 19plus V2 will not execute the store data
in FLASH memory portion of those commands while logging data.
SL
Output last sample from buffer (obtained
with polled sampling, or latest sample
from logging), and leave power on.
SLT
Output last sample from buffer, then take
new sample and store data in buffer.
Leave power on. Data is not stored in
FLASH memory.
TS
Take new sample, store data in buffer,
output data, and leave power on. Data is
not stored in FLASH memory.
TSS
Take new sample, store data in buffer
and FLASH memory, output data, and
turn power off.
TSSOn
Take new sample, store data in buffer
and FLASH memory, output data, and
leave power on.
GetLastSamples:x
Output last x samples from FLASH
memory. If x is greater than the number of
samples in memory, 19plus V2 outputs all
samples in memory. If x is omitted,
19plus V2 outputs just the last sample.
You do not need to stop logging
(magnetic switch or Stop command)
before sending GetLastSamples:x.

Testing Commands
Note:
Testing commands do not
automatically turn the pump on.
Thus, for instruments plumbed with
the pump, they report data from
essentially the same sample of
water for all 100 measurements,
because the pump does not run but
the pump and associated plumbing
prevent water from freely flowing
through the conductivity cell and
other plumbed sensors (for
example, dissolved oxygen sensor).
To get data from fresh samples,
send PumpOn before sending
a testing command, and then
send PumpOff when the test
is complete.
The 19plus V2 takes and outputs 100 samples for each test (except as noted);
data is not stored in FLASH memory. Press the Esc key (or send a break
character) to stop a test.

For example, if the 19plus V2 is
programmed to wake up and
sample at 12:00:00, and
DelayBeforeSampling=20, the output
time for the first sample will be
12:00:21 or 12:00:22.
The SBE 19plus V2 stores data in a compact machine code. Data is converted
and output in the user-selected format without affecting data in memory.
Because memory data remains intact until deliberately overwritten, you can
upload in one format, then choose another format and upload again.
Output format is dependent on OutputFormat= (0, 1, 2, 3, 4, or 5) and on the
command used to retrieve the data, as detailed below. The inclusion of some
data is dependent on the system configuration - if the system does not include
the specified sensor, the corresponding data is not included in the output data
stream, shortening the data string. RS-232 sensors always output data in the
same format, regardless of OutputFormat=:
• SBE 38, GTD, and Optode data is always output in engineering units.
• WET Labs RS-232 sensor data is always output in raw counts.
If in Moored mode and outputting real-time data (MooredTxRealTime=Y)
while logging, a # sign precedes the real-time output for each sample.

Notes:
• If you will be using Seasave to
acquire real-time data, you must set
OutputFormat=0.
• When using Seaterm232’s Upload
menu, Seaterm232 always uploads
data from memory in raw hex,
regardless of the user-programmed
format, providing the data in a format
that SBE Data Processing can use.
• Our software uses the equations
shown to perform these calculations;
alternatively, you can use the
equations to develop your own
processing software.
• The pressure sensor is an absolute
sensor, so its raw output includes
the effect of atmospheric pressure
(14.7 psi). As shown on the
Calibration Sheet, Sea-Bird’s
calibration (and resulting calibration
coefficients) is in terms of psia.
However, when outputting pressure
in engineering units, the 19plus V2
outputs pressure relative to the
ocean surface (i.e., at the surface
the output pressure is 0 decibars).
The 19plus V2 uses the following
equation to convert psia to decibars:
pressure (db) =
[pressure (psia) - 14.7] * 0.689476

Section 4: Deploying and Operating SBE 19plus V2
SBE 19plus V2
Optimizing Data Quality for Profiling Applications
Our deployment recommendations are only general guidelines, and are
focused primarily on maximizing data quality. Actual sea state conditions, and
winch and deck gear configurations, may require some adaptation in order to
achieve best data quality and avoid mechanical problems.
The SBE 19plus V2 is optimized for profiling rates of 0.5 to 2 meters/second,
with 1 meter/second generally providing the best compromise between data
quality and profile resolution. The 19plus V2 pump maintains a constant and
optimum flow rate, which ensures that the sensor response times are not
dependent on the profiling rate. Adjust the profiling rate of the 19plus V2
based on the amount of ship motion (i.e., sea state) imparted to the cable, and
the size, weight, and drag of the underwater package at the end of the cable.
Generally, use a faster rate in rougher seas, allowing the 19plus V2 to stay
clear of turbulent wakes that are shed downward when the ship heaves up;
shed wakes are an error source from which all CTDs suffer. When the sea is
very calm, the 19plus V2 can be lowered more slowly (for example,
10 to 20 cm/second) to give greater vertical resolution.
Like for other CTDs, the common configurations of the 19plus V2 are
intended for obtaining downcast data, because the sensors are oriented so that
the T-C Duct inlet passes through relatively undisturbed water as the CTD is
lowered. As the CTD is raised (upcast), the sensors sample the turbulent wake
of the package, resulting in lower quality data. If planning to sample on the
upcast, consider the following:
• Vertical orientation – In the typical, sensors-down configuration, the
sensors are in the wake of the housing on the upcast, providing poor data
quality. If you must have good quality upcast data, invert the 19plus V2 so
that the T-C Duct is at the top (ignore the downcast data for this
configuration).
• Horizontal orientation (for example, under SBE 32 Carousel Water
Sampler) - Position other instruments, sample bottles, etc. so that they are
not directly above the T & C sensors and do not thermally contaminate the
water that flows to the sensors at the T-C Duct inlet.
When a 19plus V2 is installed on a water sampler, good conductivity and
optional dissolved oxygen data can be collected, even when stopped to collect
a water sample, because water continues to flow through the sensors at a fixed
and optimal rate.
Whether sampling on the upcast and/or downcast, position the T-C Duct
inlet so that other instruments, sample bottles, etc. do not thermally
contaminate the water that flows past the sensors.
Note:
See Pump Operation – Profiling
Mode for information on the minimum
soak time required to ensure proper
pump operation.
Where the water temperature is very different from the temperature at which
the 19plus V2 has been stored, better results are obtained if the 19plus V2 is
allowed to equilibrate to the water temperature at the surface (soak) for several
(3 – 5) minutes before beginning the profile. The reason is not that the
electronics are temperature sensitive - they are not - but that the thermal
influence of the instrument housing on the water entering the cell will be
reduced. If the difference between water and storage temperature is extreme,
allow more soak time.

Manual revision 006
Section 4: Deploying and Operating SBE 19plus V2
SBE 19plus V2
When very heavy seas cause severe ship motion, the 19plus V2 descent can
actually stop or reverse direction if the ship heaves upward faster than the
package can descend. These occurrences can often be seen as loops in the realtime temperature trace. If the winch payout rate is too high, a loop of wire can
form under water when the package descent is slowed or reversed by ship
heave and the winch is still paying out wire. Inevitably, the loop formation
gets out of phase with the heave and the loop closes on itself when the ship
heaves, causing a kink. If the package includes a Carousel Water Sampler as
well as the CTD, the package creates much more drag than with only the CTD,
further increasing the possibility that a loop will form in the cable. After
1000 to 2000 meters of cable are paid out, it can be difficult or impossible to
detect a loop in the cable. Adding 100 to 200 kg (maybe more by
experimentation) of lead weights to the Carousel frame will help overcome the
effect of drag, and allow the package to descend faster and stay more in line
directly below the overboarding sheave.
Spiking is sometimes seen in the derived values for salinity, density, or sound
velocity. Spiking results largely from a response time mismatch of the
conductivity and temperature sensors, especially when the profiling descent
rate is non-uniform. The greatest reduction in spiking is found by using
premium CTD equipment such as the SBE 9plus, which uses very fast sensors
(0.07 second) and high speed (24 Hz) parallel signal acquisition. The 19plus
V2 static accuracy is the same as that of the 9plus, but its dynamic responses
are not as ideal, as a result of its simpler, less costly, and more compact
design. Much of the spiking can be removed from the data set by aligning the
data in time. This alignment can be performed when post-processing the data
in SBE Data Processing.
Note:
See the SBE Data Processing
manual for information on data
processing modules that can correct
data for the influences of ship motion
and minimize salinity spiking.
The amount of spiking depends on the temperature gradient, and is much
worse when coupled surface motion causes the instrument to stop - or even
reverse - its descent. In the event of heavy ship motion, it may be worth letting
the instrument free-fall. When very heavy seas cause severe ship motion and
result in periodic reversals of the instrument descent, the data set can be
greatly improved by removing scans taken when the pressure is not increasing,
using SBE Data Processing.

Setup for Deployment
1.
Install new batteries or ensure the existing batteries have enough capacity
to cover the intended deployment (see Replacing/Recharging Batteries in
Section 5: Routine Maintenance and Calibration).
2.
Program the 19plus V2 for the intended deployment using Seaterm232
(see Section 3: Power and Communications Test for connection
information; see this section for setup/configuration, sampling modes,
pump operation, and commands):
A. Set the date and time (DateTime=).
B. Ensure all data has been uploaded, and then send InitLogging to
make the entire memory available for recording. If InitLogging is not
sent, data will be stored after the last recorded sample.
C. Establish the setup and logging parameters.
If you will be using Seasave to acquire and view real-time data,
you must set OutputFormat=0 (raw hexadecimal).
D. Send GetCD or DS to verify the setup.
E. If desired, use StartDateTime= and StartLater to establish delayed
start date and time for Profiling mode (if IgnoreSwitch=Y) or
Moored mode.
Note:
A new or recalibrated CTD ships
with a configuration file that reflects
the current configuration as we
know it. The file is named with the
instrument serial number, followed
by a .xmlcon extension. For
example, for a CTD with serial
number 2375, Sea-Bird names the
file 2375.xmlcon. You may rename
the file (but not the extension) if
desired; this will not affect the
results.
3.
If you will be using Seasave to acquire and view real-time data, verify that
the configuration (.xmlcon or .con) file matches the instrument
configuration. Sea-Bird supplies a configuration file to match the factory
configuration and calibrations. If the instrument is recalibrated or the
configuration is changed (such as by adding external sensors), the
configuration file must be updated to reflect the current condition. See
Verifying Contents of Configuration (.xmlcon or .con) File.
4.
If you will be using Seaterm232 to view real-time data, click the Capture
menu to save the data to a file. Enter the desired capture file name in the
dialog box, and click Save.

Section 4: Deploying and Operating SBE 19plus V2
SBE 19plus V2
Acquiring Real-Time Data with Seasave
Notes:
• Seasave and SBE Data Processing
versions 7.20a introduced .xmlcon
files (in XML format). Versions 7.20a
and later allow you to open a .con or
.xmlcon file, and to save it to a .con
or .xmlcon file. Seasave and SBE
Data Processing use the same file.
• A new or recalibrated CTD ships
with a configuration file that reflects
the current configuration as we know
it. The file is named with the
instrument serial number, followed
by a .con extension. For example,
for a CTD with serial number 2375,
Sea-Bird names the file 2375.con.
You may rename the file (but not the
extension) if desired; this will not
affect the results.
• In the 19plus V2 setup commands,
external voltage numbers 0, 1, 2, 3,
4, and 5 correspond to wiring of
sensors to a voltage channel on the
end cap (see Dimensions and End
Cap Connectors in Section 2:
Description of SBE 19plus V2).
However, in the .xmlcon or .con file,
voltage 0 is the first external voltage
in the data stream, voltage 1 is the
second, etc.
Verifying Contents of Configuration (.xmlcon or .con) File
Seasave, our real-time data acquisition and display program, requires a
configuration file, which defines the CTD – integrated auxiliary sensors, and
channels, serial numbers, and calibration dates and coefficients for all the
sensors (conductivity, temperature, and pressure as well as auxiliary sensors).
Seasave (as well as our data processing software) uses the information in the
configuration file to interpret and process the raw data. If the configuration
file does not match the actual instrument configuration, the software will
not be able to interpret and process data correctly.

SBE 19plus V2
Acquiring Real-Time Data
Instructions below are for an SBE 19plus V2 with a conventional single-core
armored cable, used without a Sea-Bird Deck Unit. If using the 19plus V2
with the SBE 33 or 36 Deck Unit or the SEACAT/SEALOGGER RS-232
and Navigation Interface Box, see the Deck Unit or Interface Box manual.
Note:
The baud rate between the 19plus V2
and computer (defined in Configure
Inputs, on the Serial Ports tab) must
match the baud rate set in the
19plus V2 with BaudRate=.
1.
Wiring - Terminate the single-core armored cable with an RMG-4FS
connector (19plus V2 with standard connectors) or MCIL-4FS (19plus V2
with optional wet-pluggable connectors). Wire the cable armor to pin 1
(large pin for 19plus V2 with standard connectors) and the inner
conductor to pin 3 (opposite large pin) on the 19plus V2 data I/O - power
connector (4-pin leg on Y-cable connected to Data I/O, Pump, and
External Power bulkhead connector). On deck, wire:
Slip-ring lead
25-pin serial port
9-pin serial port
from armor
Pin 7
Pin 5
from inner conductor

4.
In the Real-Time Data menu, select Start. The dialog box looks like this:
Data Archiving Options:
• Begin archiving data immediately to store raw (frequencies,
A/D counts, and/or voltages) real-time data as soon as Start
button is clicked and communication is established.
• Begin archiving data when ‘Start Archiving’ command is
sent to control when data begins to be written to file. This allows
you to eliminate scans associated with deploying CTD from ship
deck and soaking instrument near surface (alternatively, remove
these scans later in SBE Data Processing). If you make this
selection, when you click Start button and communication is
established, a dialog box with Start Archiving button appears.
Click this button when ready to begin saving scans to file, or
select Start Archiving in Real-Time Data menu.
• Do not archive data for this cast to not save data to a file.
Real-time data will still appear in displays.
Configuration Options: Currently selected instrument configuration
(.xmlcon or .con) file is shown, containing information on number and
type of sensors interfacing with 19plus V2, calibration coefficients,
and inclusion of NMEA and/or Surface PAR data with output from
CTD. To modify input configuration (.xmlcon or .con file, serial ports,
water sampler, TCP/IP ports, and/or miscellaneous), click Configure
Inputs. To modify outputs (serial data output, serial ports, shared file
output, mark variables, TCP/IP output, TCP/IP ports, SBE 14 remote
display, PC alarms, header form, and/or diagnostics), click Configure
Outputs.
• Timeout in seconds at startup: Time allowed before first data
scan is received from 19plus V2. Seasave will time out and stop
attempting to acquire data if data is not received from 19plus V2
within this time period.
• Timeout in seconds between scans: Maximum gap allowed
between scans after first data scan is received from 19plus V2.
Seasave will time out and stop attempting to acquire data if data is
not received from 19plus V2 within this time period (for example, if a
shark bites cable and interrupts data acquisition, Seasave stops
attempting to acquire data after this gap).

the configuration file matches the 19plus V2 (i.e., number of sensors
and inclusion of NMEA is as defined in the file). If a Scan length error
appears, verify that:
• You are using the correct .xmlcon or .con configuration file.
• The configuration file has been updated as necessary if you added
or deleted sensors, added or deleted NMEA or Surface PAR, etc.
D. Seasave sends a message: Waiting for data. . . If you have already
started logging data, ignore the message; otherwise, slide the
magnetic switch to the On position or apply external power, as
applicable to your setup of the 19plus V2. Seasave times out if data is
not received within Timeout in seconds at startup.
E. Real-time data then starts appearing in the screen displays.
6.
To stop real-time data acquisition: In the Real-Time Data menu,
select Stop.
7.
Stop logging:
• If IgnoreSwitch=N and AutoRun=N: Put the magnetic switch in the
Off position.
• If IgnoreSwitch=Y and AutoRun=N: Close Seasave, then open
Seaterm232 and send Stop.
• If AutoRun=Y: Remove external power.
Notes:
• If in Moored mode, the 19plus V2
must be sampling autonomously to
use Seasave for real-time data
acquisition. Start sampling by
sending StartNow or StartLater in
Seaterm232 before starting
acquisition in Seasave.
• To prevent problems in the use of
the COM port, click Disconnect in

Recovery
WARNING!
If the 19plus V2 stops working while
underwater, is unresponsive to
commands, or shows other signs of
flooding or damage, carefully
secure it away from people until you
have determined that abnormal
internal pressure does not exist or
has been relieved. Pressure housings
may flood under pressure due to dirty
or damaged o-rings, or other failed
seals. When a sealed pressure
housing floods at great depths and is
subsequently raised to the surface,
water may be trapped at the pressure
at which it entered the housing,
presenting a danger if the housing is
opened before relieving the internal
pressure. Instances of such flooding
are rare. However, a housing that
floods at 5000 meters depth holds an
internal pressure of more than
7000 psia, and has the potential to
eject the end cap with lethal force.
A housing that floods at 50 meters
holds an internal pressure of more
then 85 psia; this force could still
cause injury.
If you suspect the 19plus V2 is
flooded, point the 19plus V2 in a safe
direction away from people, and
loosen 1 end cap bulkhead connector
very slowly, at least 1 turn. This opens
an o-ring seal under the connector.
Look for signs of internal pressure
(hissing or water leak). If internal
pressure is detected, let it bleed off
slowly past the connector o-ring. Then,
you can safely remove the end cap.
Physical Handling
1.
Rinse the instrument and conductivity cell with fresh water.
(See Section 5: Routine Maintenance and Calibration for cell cleaning
and storage.)
2.
If the batteries are exhausted, new batteries must be installed before the
data can be extracted. Stored data will not be lost as a result of exhaustion
or removal of batteries. (See Section 5: Routine Maintenance and
Calibration for replacement of batteries.)
3.
If immediate redeployment is not required, it is best to leave the
19plus V2 with batteries in place and in a quiescent state (QS). Because
the quiescent current required is only 20 microamps, the batteries can be
left in place without significant loss of capacity. If the 19plus V2 is to be
stored for a long time, replace the batteries yearly to prevent battery
leakage (which could damage the 19plus V2).

D. If there is still no communication, repeat Step A with a different baud
rate and/or comm port, and try to connect again. Note that the
factory-set baud rate is documented on the Configuration Sheet.
4.
Command the 19plus V2 to stop data logging by the method applicable to
your instrument’s setup:
• Pressing the Enter key, typing Stop, and pressing the Enter key again,
or

Notes:
To prepare for redeployment:
1. After all data has been uploaded,
send InitLogging. If this command
is not sent, new data will be stored
after the last recorded sample,
preventing use of the entire
memory capacity.
2. Send QS to put the 19plus V2 in
quiescent (sleep) state until ready
to redeploy. Quiescent current
is only 20 microamps, so the
batteries can be left in place
without significant loss of capacity.

SBE 19plus V2
Ensure all data has been uploaded by reviewing and processing the data:
A. Use Seasave to display and plot the raw hexadecimal data in
engineering units (see Verifying Contents of Configuration (.xmlcon
or .con) File and Seasave’s manual/Help files).
B. Use SBE Data Processing to process and plot the data (see
Processing Data Using SBE Data Processing and SBE Data
Processing manual/Help files).

Manual revision 006
Section 4: Deploying and Operating SBE 19plus V2
SBE 19plus V2
Processing Data Using SBE Data Processing
Notes:
• Seasave and SBE Data Processing
versions 7.20a introduced .xmlcon
files (in XML format). Versions 7.20a
and later allow you to open a .con or
.xmlcon file, and to save it to a .con
or .xmlcon file. Seasave and SBE
Data Processing use the same file.
• A new or recalibrated CTD ships
with a configuration file that reflects
the current configuration as we know
it. The file is named with the
instrument serial number, followed
by a .con extension. For example,
for a CTD with serial number 2375,
Sea-Bird names the file 2375.con.
You may rename the file (but not the
extension) if desired; this will not
affect the results.
• In the 19plus V2 setup commands,
external voltage numbers 0, 1, 2, 3,
4, and 5 correspond to wiring of
sensors to a voltage channel on the
end cap (see Dimensions and End
Cap Connectors in Section 2:
Description of SBE 19plus V2).
However, in the .xmlcon or .con file,
voltage 0 is the first external voltage
in the data stream, voltage 1 is the
second, etc.
1.
Convert the .hex (raw data) file (real-time file from Seasave or uploaded
from 19plus V2 memory) to a .cnv (engineering units) file in
SBE Data Processing’s Data Conversion module.
2.
Once the data is converted: perform further processing (align, filter,
remove bad data, etc.), calculate derived variables, and plot data using
SBE Data Processing’s other modules.
Verifying Contents of Configuration (.xmlcon or .con) File
To convert the .hex (raw data) file, you need a .xmlcon or .con configuration
file, which defines the instrument – integrated sensors, and channels, serial
numbers, and calibration dates and coefficients for all sensors (C, T, and P as
well as auxiliary sensors). SBE Data Processing (as well as our real-time data
acquisition software) uses the configuration file information to interpret and
process the raw data. If the configuration file does not match the actual
instrument configuration, the software will be unable to interpret and
process the data correctly.
To view or modify the .xmlcon or .con file:
1.
Double click on SBEDataProc.exe.
2.
In the Configure menu, select SBE 19plus V2 Seacat CTD. The
configuration dialog box appears; click Open.

Editing Raw Data File
Sometimes users want to edit the raw .hex data file before beginning
processing, to remove data at the beginning of the file corresponding to
instrument soak time, to remove blocks of bad data, to edit the header, or to add
explanatory notes about the cast. Editing the raw .hex file can corrupt the
data, making it impossible to perform further processing using Sea-Bird
software. Sea-Bird strongly recommends that you first convert the data to a
.cnv file (using the Data Conversion module in SBE Data Processing), and then
use other SBE Data Processing modules to edit the .cnv file as desired.
Note:
Although we provide this
technique for editing a raw .hex
file, Sea-Bird’s strong
recommendation, as described
above, is to always convert the
raw data file and then edit the
converted file.
The procedure for editing a .hex data file described below has been found to
work correctly on computers running Windows 98, 2000, and NT. If the
editing is not performed using this technique, SBE Data Processing may
reject the edited data file and give you an error message.
1.
Make a back-up copy of your .hex data file before you begin.
2.
Run WordPad.
3.
In the File menu, select Open. The Open dialog box appears. For Files of
type, select All Documents (*.*). Browse to the desired .hex data file and
click Open.
4.
Edit the file as desired, inserting any new header lines after the System
Upload Time line. Note that all header lines must begin with an asterisk
(*), and *END* indicates the end of the header. An example is shown

SBE 19plus V2
Section 5: Routine Maintenance
and Calibration
This section reviews corrosion precautions, connector mating and
maintenance, plumbing maintenance, replacement/recharging batteries,
conductivity cell storage and cleaning, pressure sensor maintenance,
replacement of optional Anti-Foulant Devices, and sensor calibration. The
accuracy of the SBE 19plus V2 is sustained by the care and calibration of the
sensors and by establishing proper handling practices.
Corrosion Precautions
Rinse the SBE 19plus V2 with fresh water after use and prior to storage.
For both the plastic and titanium housing, all exposed metal is titanium
(the plastic housing has a titanium end cap). No corrosion precautions are
required, but avoid direct electrical connection of the titanium to dissimilar
metal hardware.
Connector Mating and Maintenance
Note:
See Application Note 57: Connector
Care and Cable Installation.
CAUTION:
Do not use WD-40 or other
petroleum-based lubricants, as they
will damage the connectors.
Clean and inspect connectors, cables, and dummy plugs before every cruise,
during a cruise (good practice if you have a few days of down time between
casts), after every cruise, and as part of your yearly equipment maintenance.
Inspect connectors that are unmated for signs of corrosion product around the
pins, and for cuts, nicks or other flaws that may compromise the seal.
When remating:
1. Lightly lubricate the inside of the dummy plug/cable connector with
silicone grease (DC-4 or equivalent).
2. Standard Connector - Install the plug/cable connector, aligning the
raised bump on the side of the plug/cable connector with the large pin
(pin 1 - ground) on the 19plus V2. Remove any trapped air by burping or
gently squeezing the plug/connector near the top and moving your fingers
toward the end cap. OR
MCBH Connector – Install the plug/cable connector, aligning the pins.
3. Place the locking sleeve over the plug/cable connector. Tighten the
locking sleeve finger tight only. Do not overtighten the locking sleeve
and do not use a wrench or pliers.
Verify that a cable or dummy plug is installed for each connector on the
system before deployment.

For an SBE 19plus V2 with plumbing configured for vertical orientation A clogged air release valve can trap air, preventing the pump from
functioning properly; this will affect the data quality. Periodically clean the
air release valve:
1.
Use a 0.4 mm (0.016 inches) diameter wire (you can use #26 AWG wire)
to clean the valve. The easiest way to do this is to remove the Tygon
tubing above the air release valve, and use needle-nosed pliers to force the
wire through the hole.
2.
Blow through the air release valve to ensure it is open.
3.
(if applicable) Replace the Tygon tubing above the air release valve.

Replacing / Recharging Batteries
Note:
If changing from alkaline to Ni-Cad
or NiMH batteries, or vice versa,
send BatteryType= to indicate the
new battery type.
Leave the batteries in place when storing the SBE 19plus V2 to prevent
depletion of the back-up lithium batteries by the real-time clock. Even
exhausted main batteries will power the clock (20 microamperes) almost
indefinitely. If the 19plus V2 is to be stored for long periods, replace the
batteries yearly to prevent battery leakage (which could damage the
19plus V2).
Replacing Alkaline Batteries
Alkaline D-cell
(MN1300, LR20)
The 19plus V2 uses alkaline D-cells (Duracell MN1300, LR20), dropped into
the battery compartment.
1.
Remove the battery end cap (end cap without connectors):
A. Wipe the outside of the end cap and housing dry, being careful to
remove any water at the seam between them.
B. Unthread the end cap by rotating counter-clockwise (use a wrench on
the white plastic bar if necessary).
C. Remove any water from the O-ring mating surfaces inside the
housing with a lint-free cloth or tissue.
D. Put the end cap aside, being careful to protect the O-ring from
damage or contamination.
2.
Remove the battery cover plate from the housing:
A. Remove the three Phillips-head screws and washers from the battery
cover plate inside the housing.
B. The battery cover plate will pop out. Put it aside.
3.
Turn the 19plus V2 over and remove the batteries.
4.
Install the new batteries, with the + terminals against the flat battery
contacts and the - terminals against the spring contacts.
5.
Reinstall the battery cover plate in the housing:
A. Align the battery cover plate with the housing. The posts inside the
housing are not placed symmetrically, so the cover plate fits into the
housing only one way. Looking at the cover plate, note that one screw
hole is closer to the edge than the others, corresponding to the post
that is closest to the housing.
B. Reinstall the three Phillips-head screws and washers, while pushing
hard on the battery cover plate to depress the spring contacts at the
bottom of the battery compartment. The screws must be fully
tightened, or battery power to the circuitry will be intermittent.
6.
Check the battery voltage at BAT + and BAT - on the battery cover plate.
It should be approximately 13.5 volts.
7.
Reinstall the battery end cap:
A. Remove any water from the O-rings and mating surfaces with a lintfree cloth or tissue. Inspect the O-rings and mating surfaces for dirt,
nicks, and cuts. Clean or replace as necessary. Apply a light coat
of o-ring lubricant (Parker Super O Lube) to O-rings and
mating surfaces.
B. Carefully fit the end cap into the housing and rethread the end cap
into place. Use a wrench on the white plastic bar to ensure the
end cap is tightly secured.

Section 5: Routine Maintenance and Calibration
SBE 19plus V2
Conductivity Cell Maintenance
CAUTIONS:
• Do not put a brush or any object
inside the conductivity cell to
dry it or clean it. Touching and
bending the electrodes can
change the calibration. Large
bends and movement of the
electrodes can damage the cell.
• Do not store the 19plus V2 with
water in the conductivity cell.
Freezing temperatures (for
example, in Arctic environments or
during air shipment) can break the
cell if it is full of water.
Barbed caps for cleaning
and storage
The SBE 19plus V2’s conductivity cell is shipped dry to prevent freezing
in shipping. Refer to Application Note 2D: Instructions for Care and Cleaning
of Conductivity Cells for conductivity cell cleaning and storage procedures
and materials.
The 19plus V2 is shipped with a kit for cell filling and storage. The kit
includes:
• Syringe and tubing assembly, and
• Two anti-foulant device caps with hose barbs. These caps are used during
cleaning and storage only if you installed anti-foul fittings for a moored
application, because the tubing cannot attach to an anti-foulant device cap
that is not barbed. The cap used during deployment on one or both ends of
the conductivity cell may not be barbed, depending on your system
configuration (see Installing Anti-Foul Fittings for Moored Applications
in Section 4: Deploying and Operating SBE 19plus V2). As needed,
remove the installed, non-barbed anti-foulant device cap(s) and replace
them with the caps with hose bars for cleaning and storage only.
Remember to reinstall the original cap(s) before deployment. Deploying
an SBE 19plus V2 with barbed anti-foulant device cap(s) in place of
the installed caps is likely to produce undesirable results in your data.

Pressure Sensor Maintenance
CAUTION:
Do not put a brush or any object in

damage or break the pressure sensor.
Pressure sensor maintenance varies, depending on the type of pressure sensor
in your SBE 19plus V2.
Strain-Gauge Pressure Sensor
Pressure
sensor
port
Periodically (approximately once a year) inspect the pressure port for particles
and debris. Rinse the pressure port with warm, de-ionized water to remove any
particles, debris, etc.
Quartz Pressure Sensor
Nylon pressure capillary fitting for 19plus V2
with Quartz pressure sensor
At the factory, the pressure sensor and pressure port were filled with a silicon
oil, and a nylon pressure capillary fitting – which includes a pressure port
fitting and an external capillary tube – were used to retain the oil. The oil
transmits hydrostatic pressure via internal, stainless steel, capillary tubing to
the pressure sensor inside the instrument, and prevents corrosion that might
occur if the sensor diaphragm was exposed to water. The internal tubing and
nylon capillary fitting are vacuum back-filled at the factory.
Because of the viscosity of the silicone oil and capillary action, the silicone oil
does not run out of the external capillary tube. However, due to temperature
and pressure cycling over long periods, it is normal for some oil to slowly leak
out of the external capillary tube. When the oil is not visible or is receding
inside the translucent tube, or if the fitting has been damaged, refill the oil
using the supplied pressure sensor oil refill kit. See Application Note 12-1:
Pressure Port Oil Refill Procedure & Nylon Capillary Fitting Replacement.

Section 5: Routine Maintenance and Calibration
SBE 19plus V2
Sensor Calibration
Note
After recalibration, Sea-Bird enters
the new calibration coefficients in the
19plus V2 EEPROM, and ships the
instrument back to the user with
Calibration Certificates showing the
new coefficients. We also ship a new
instrument configuration (.con) file,
which includes the new coefficients.
Sea-Bird sensors are calibrated by subjecting them to known physical
conditions and measuring the sensor responses. Coefficients are then
computed, which may be used with appropriate algorithms to obtain
engineering units. The conductivity, temperature, and pressure sensors on the
SBE 19plus V2 are supplied fully calibrated, with coefficients stored in
EEPROM in the 19plus V2 and printed on their respective Calibration
Certificates.
We recommend that the 19plus V2 be returned to Sea-Bird for calibration.
Conductivity Sensor
The conductivity sensor incorporates a fixed precision resistor in parallel with
the cell. When the cell is dry and in air, the sensor’s electrical circuitry outputs
a frequency representative of the fixed resistor. This frequency is recorded on
the Calibration Certificate and should remain stable (within 1 Hz) over time.
The primary mechanism for calibration drift in conductivity sensors is the
fouling of the cell by chemical or biological deposits. Fouling changes the cell
geometry, resulting in a shift in cell constant.
Accordingly, the most important determinant of long-term sensor accuracy is
the cleanliness of the cell. We recommend that the conductivity sensors be
calibrated before and after deployment, but particularly when the cell has been
exposed to contamination by oil slicks or biological material.
Temperature Sensor
The primary source of temperature sensor calibration drift is the aging of the
thermistor element. Sensor drift will usually be a few thousandths of a degree
during the first year, and less in subsequent intervals. Sensor drift is not
substantially dependent upon the environmental conditions of use, and —
unlike platinum or copper elements — the thermistor is insensitive to shock.

Manual revision 006
Section 5: Routine Maintenance and Calibration
SBE 19plus V2
Pressure Sensor
The SBE 19plus V2 includes a standard strain-gauge pressure sensor or
optional Quartz pressure sensor. These sensors are capable of meeting the
19plus V2 error specification with some allowance for aging and ambienttemperature induced drift.
Pressure sensors show most of their error as a linear offset from zero. A
technique is provided below for making small corrections to the pressure sensor
calibration using the offset (POffset=) calibration coefficient term by comparing
19plus V2 pressure output to readings from a barometer.
Note:
The pressure sensor is an absolute
sensor, so its raw output includes the
effect of atmospheric pressure
14.7 psi). As shown on the
Calibration Sheet, Sea-Bird’s
calibration (and resulting calibration
coefficients) is in terms of psia.
However, when outputting pressure
in engineering units, the 19plus V2
outputs pressure relative to the ocean
surface (i.e., at the surface the output
pressure is 0 decibars).
The 19plus V2 uses the following
equation to convert psia to decibars:
pressure (db) =
[pressure (psia) - 14.7] * 0.689476
Allow the 19plus V2 to equilibrate (with power on) in a reasonably constant
temperature environment for at least 5 hours before starting. Pressure sensors
exhibit a transient change in their output in response to changes in their
environmental temperature. Sea-Bird instruments are constructed to minimize
this by thermally decoupling the sensor from the body of the instrument.
However, there is still some residual effect; allowing the 19plus V2 to
equilibrate before starting will provide the most accurate calibration correction.
1.
Place the 19plus V2 in the orientation it will have when deployed.
2.
In Seaterm232:
A. Set the pressure offset to 0.0 (POffset=0).
B. Send TP to measure the 19plus V2 pressure 100 times and transmit
converted data in engineering units (decibars).
3.
Compare the 19plus V2 output to the reading from a good barometer at the
same elevation as the 19plus V2 pressure sensor.
Calculate offset = barometer reading – 19plus V2 reading
4.
Enter the calculated offset (positive or negative) in two places:
• In the 19plus V2 EEPROM, using POffset= in Seaterm232, and
• In the configuration (.xmlcon or .con) file, using Seasave or SBE Data
Processing.
Offset Correction Example
Absolute pressure measured by a barometer is 1010.50 mbar. Pressure displayed from 19plus V2 is -2.5 dbars.
Convert barometer reading to dbars using the relationship: mbar * 0.01 = dbar
Barometer reading = 1010.50 mbar * 0.01 = 10.1050 dbar
The 19plus V2’s internal calculations and our processing software output gage pressure, using an assumed
value of 14.7 psi for atmospheric pressure. Convert 19plus V2 reading from gage to absolute by adding
14.7 psia to the 19plus V2 output:
-2.5 dbars + (14.7 psi * 0.689476 dbar/psia) = -2.5 + 10.13 = 7.635 dbars
Offset = 10.1050 – 7.635 = + 2.47 dbars
Enter offset in 19plus V2 and in .xmlcon or .con file.
For demanding applications, or where the sensor’s air ambient pressure
response has changed significantly, calibration using a dead-weight
generator is recommended. The end cap’s 7/16-20 straight thread permits
mechanical connection to the pressure source. Use a fitting that has an O-ring
tapered seal, such as Swagelok-200-1-4ST, which conforms to MS16142 boss.

Section 6: Troubleshooting
SBE 19plus V2
Section 6: Troubleshooting
This section reviews common problems in operating the SBE 19plus V2, and
provides the most common causes and solutions.
Problem 1: Unable to Communicate
If OutputExecutedTag=N, the S> prompt indicates that communications
between the SBE 19plus V2 and computer have been established. Before
proceeding with troubleshooting, attempt to establish communications again
by clicking Connect in the Communications menu in Seaterm232 or pressing
the Enter key several times.
Cause/Solution 1: The I/O cable connection may be loose. Check the cabling
between the 19plus V2 and computer for a loose connection.
Cause/Solution 2: The instrument communication settings may not have been
entered correctly in Seaterm232. Verify the settings in the Serial Port
Configuration dialog box (Communication menu -> Configure). The settings
should match those on the instrument Configuration Sheet.
Cause/Solution 3: The I/O cable may not be the correct one. The I/O cable
supplied with the 19plus V2 permits connection to standard 9-pin RS-232
interfaces. See Dimensions and End Cap Connectors in Section 2: Description
of SBE 19plus V2 for cable pinouts.
Problem 2: No Data Recorded
Cause/Solution 1: The memory may be full; once the memory is full, no
further data is recorded. Verify that the memory is not full using GetSD or DS
(free = 0 or 1 if memory is full). Sea-Bird recommends that you upload all
previous data before beginning another deployment. Once the data is
uploaded, use InitLogging to reset the memory. After the memory is reset,
GetSD or DS will show samples = 0.
103
Manual revision 006
Section 6: Troubleshooting
SBE 19plus V2
Problem 3: Nonsense or Unreasonable Data
The symptom of this problem is a data file that contains nonsense values (for
example, 9999.999) or unreasonable values (for example, values that are
outside the expected range of the data).
Note:
Each 19plus V2 is shipped with a
configuration (.con) file that matches
the configuration of the instrument
(number and type of auxiliary
sensors, etc.) and includes the
instrument calibration coefficients.
Cause/Solution 1: A data file with nonsense values may be caused by
incorrect instrument configuration:
• Bad data may be caused by incorrect configuration in the 19plus V2. Send
GetCD or DS to verify the 19plus V2 setup matches the instrument
Configuration Sheet (correct pressure sensor, voltage sensors assigned to
correct channels, etc).
• Bad data may be caused by incorrect configuration in the instrument
.xmlcon or .con configuration file. Verify the settings in the configuration
file match the instrument Configuration Sheet.
Cause/Solution 2: A data file with unreasonable (i.e., out of the expected
range) values for temperature, conductivity, etc. may be caused by incorrect
calibration coefficients:
• If you manually uploaded data in engineering units (OutputFormat=1, 3,
or 5) – Bad data may be caused by incorrect calibration coefficients in the
19plus V2. Send GetCC or DCal to verify the calibration coefficients in
the 19plus V2 match the instrument Calibration Certificates. Note that
calibration coefficients do not affect the raw data stored in 19plus V2
memory. If you have not yet overwritten the memory with new data, you
can correct the coefficients and then upload the data again.
• If you are viewing real-time data in Seasave, manually uploaded data in
raw hexadecimal (OutputFormat=0), or used Seaterm232’s Upload
menu to upload data and are processing the data in Seasave or SBE Data
Processing - Bad data may be caused by incorrect calibration coefficients
in the instrument .xmlcon or .con configuration file. Verify the calibration
coefficients in the configuration file match the instrument Calibration
Certificates.
• For RS-232 sensors interfacing to the 19plus V2: Bad data may be caused
by incorrect calibration coefficients programmed into the RS-232 sensor.
Connect the sensor directly to the computer and use Seaterm232 of
SEATERM to verify the calibration coefficients match the instrument
Calibration Certificate.
Problem 4: Program Corrupted
Note:
Using the reset switch does not affect
the 19plus V2 memory - data in
memory and user-programmable
parameter values are unaffected.
Cause/Solution 1: In rare cases, the program that controls the 19plus V2
microprocessor can be corrupted by a severe static shock or other problem.
This program can be initialized by using the reset switch. Proceed as follows
to initialize:
1. Open the battery end cap and remove the batteries
(see Replacing /Recharging Batteries in Section 5: Routine Maintenance
and Calibration).
2. There is a small, pushbutton switch on the battery compartment bulkhead,
which is visible after the batteries are removed. The switch is used to
disconnect the internal lithium batteries from the electronics. Push the
switch in for 1 second.
3. Reinstall or replace the batteries, and close the battery end cap.
4. Establish communications with the 19plus V2 (see Section 3: Power and
Communications Test). Send GetSD or DS to verify that the date and time
and sample number are correct.

Appendix I: Functional Description
and Circuitry
Sensors
The SBE19plus V2 embodies the same sensor elements (3-electrode,
2-terminal, borosilicate glass cell, and pressure-protected thermistor)
previously employed in Sea-Bird’s modular SBE 3 and SBE 4 sensors and in
the original SEACAT design. The19plus V2 differs from the SBE 19 in that it
uses three independent channels to digitize temperature, conductivity, and
pressure concurrently. Multiplexing is not used for these channels.
The pressure sensor is a strain-gauge or optional Quartz sensor.
Sensor Interface
Temperature is acquired by applying an AC excitation to a bridge circuit
containing an ultra-stable aged thermistor with a drift rate of less than 0.002 ºC
per year. The other elements in the bridge are VISHAY precision resistors.
A 24-bit A/D converter digitizes the output of the bridge. AC excitation and
ratiometric comparison avoids errors caused by parasitic thermocouples, offset
voltages, leakage currents, and reference errors.
Conductivity is acquired using an ultra-precision Wein-Bridge oscillator to
generate a frequency output in response to changes in conductivity.
Strain-gauge pressure is acquired by applying an AC excitation to the pressure
bridge. A 24-bit A/D converter digitizes the output of the bridge. AC
excitation and ratiometric comparison avoids errors caused by parasitic
thermocouples, offset voltages, leakage currents, and reference errors.
A silicon diode embedded in the pressure bridge is used to measure the
temperature of the pressure bridge. This temperature is used to perform offset
and span corrections on the measured pressure signal.
The six external 0 to 5 volt DC voltage channels are processed by differential
amplifiers with an input resistance of 50K ohms and are digitized with a 14-bit
A/D converter.
Real-Time Clock
To minimize power and improve clock accuracy, a temperature-compensated
crystal oscillator (TCXO) is used as the real-time-clock frequency source.
The TCXO is accurate to ± 1 minute per year (0 ºC to 40 ºC).

Manual revision 006
Appendix I: Functional Description and Circuitry
SBE 19plus V2
Battery Wiring
SBE 19plus V2 standard main battery is a series connection of D-cells that
drop into the battery compartment as a cluster of end-to-end stacks, three
batteries each (standard 9-cell battery pack has three stacks). The positive
battery connections are contact areas on double-thick printed circuit disks that
form the internal bulkhead and battery retainer plates. Battery negative
contacts are heavy beryllium-copper springs. The three cell stacks are aligned
by plastic insulated aluminum spacers which also serve as electrical
interconnects. The battery-to-circuit card connection is made by means of a
Molex-type 3-pin pc board connector (JP3 on the power PCB).
The Power PCB contains three series-connected Panasonic BR-2/3A lithium
cells (non-hazardous) which are diode OR’d with the main battery (and
external power source, if used). The back-up lithium supply is capable of
maintaining the buffer and the real-time clock if the main batteries and/or
external power are removed. If the back-up lithium battery voltage (Vlith in
the GetSD or DS response) falls below 7 volts, replace the back-up batteries.

There were still a few references to Toolbar (Seaterm’s toolbar, new software does not have it),
remove them.
Correct TVR (said columns 1–16 for external voltage, should be 1–6).
Add new V2 Seaspares kits in replacement parts list.
Add explanation for Hardware configuration commands: customer may change voltage sensor
types and serial numbers.
Correct XML output in Output Format section, for OutputUCSD=Y and OutputFormat=5
(closing tag for voltage was incorrect).
Delete SCPlusV2_RS232 software, add SeatermV2 software.
Firmware 2.1 – add CommandSetVersion tag in GetHD reply; change StartLater limitation from
1 month to 90 days in future.
Update for Seasave/SBE Data Processing 7.18, configuration file now allows selection of NMEA
connected directly to the computer.
