SECTION 1.0.
DESCRIPTION AND SPECIFICATIONS
• MULTI-PARAMETER INSTRUMENT – single or dual input. Choose from pH/ORP/ISE,
Resistivity/Conductivity, % Concentration, Chlorine, Oxygen, Ozone, Temperature, Turbidity, Flow,
and 4-20mA Current Input.
• LARGE DISPLAY – large easy-to-read process measurements.
• EASY TO INSTALL – modular boards, removable connectors, easy to wire power, sensors, and outputs.
• INTUITIVE MENU SCREENS with advanced diagnostics and help screens.
• SEVEN LANGUAGES included: English, French, German, Italian, Spanish, Portuguese, and Chinese.
• HART® AND PROFIBUS® DP Digital Communications options
FEATURES AND APPLICATIONS
The Model 1056 dual-input analyzer offers single or
dual sensor input with an unrestricted choice of dual
measurements. This multi-parameter instrument offers
a wide range of measurement choices supporting most
industrial, commercial, and municipal applications.
The modular design allows signal input boards to be
field replaced making configuration changes easy.
Conveniently, live process values are always displayed
during programming and calibration routines.
QUICK START PROGRAMMING: Exclusive Quick
Start screens appear the first time the Model 1056
is powered. The instrument auto-recognizes each
measurement board and prompts the user to configure
each sensor loop in a few quick steps for immediate
deployment.
DIGITAL COMMUNICATIONS: HART and Profibus
DP digital communications are available. Model 1056
HART units communicate with the Model 375 HART®
hand-held communicator and HART hosts, such as
AMS Intelligent Device Manager. Model 1056 Profibus
units are fully compatible with Profibus DP networks
and Class 1 or Class 2 masters. HART and Profibus
DP configured units will support any single or dual
measurement configuration of Model 1056.
MENUS: Menu screens for calibrating and programming
are simple and intuitive. Plain language prompts and
help screens guide the user through these procedures.
DUAL SENSOR INPUT AND OUTPUT: The Model
1056 accepts single or dual sensor input.
Standard 0/4-20 mA current outputs can be
programmed to correspond to any measurement or
temperature.
ENCLOSURE: The instrument fits standard ½ DIN
panel cutouts. The versatile enclosure design supports
panel-mount, pipe-mount, and surface/wall-mount
installations.
ISOLATED INPUTS: Inputs are isolated from other
signal sources and earth ground. This ensures clean
signal inputs for single and dual input configurations.
For dual input configurations, isolation allows any
combination of measurements and signal inputs without cross-talk or signal interference.
TEMPERATURE: Most measurements require temperature compensation. The Model 1056 will automatically recognize Pt100, Pt1000 or 22k NTC RTDs built
into the sensor.
SECURITY ACCESS CODES: Two levels of security
access are available. Program one access code for
routine calibration and hold of current outputs; program
another access code for all menus and functions.

Rosemount Analytical extends its worldwide reach by
offering seven local languages – English, French,
German, Italian, Spanish, Portuguese, and Chinese.
Every unit includes user programming menus; calibration
routines; faults and warnings; and user help screens
in all seven languages. The displayed language can
be easily set and changed using the menus.
CURRENT OUTPUTS: Two 4-20 mA or 0-20 mA current
outputs are electrically isolated. Outputs are fully scalable
and can be programmed to linear or logarithmic
modes. Output dampening can be enabled with time
constants from 0 to 999 seconds. Output 1 includes

l 4-Electrode Conductivity:
The Model 1056 is compatible with Rosemount
Analytical 4-electrode Model 410VP in the PUR-SENSE
family of conductivity sensors. This sensor supports
a wide array of applications and is capable of measuring
a large range of conductivity with one geometric
configuration. Wired to the Model 1056, this sensor
can measure 2μS/cm to 300mS/cm with an accuracy of
4% of reading throughout the entire range.
l 4-20mA Current Input: Accepts any analog current
input from an external device for temperature compensation of measurements and atmospheric pressure
input for partial pressure correction of oxygen.
l Selective Ions: The analyzer is able to measure
ammonia and fluoride using commercially available
ion-selective electrodes. All analyzers with installed pH
boards can be programmed to measure selective ions.
l pH Independent Free Chlorine: With Rosemount
Analytical’s Model 498Cl-01 sensor, the analyzer is
able to measure free chlorine with automatic correction
for process pH without the need for a pH sensor.
l Inferential pH: The analyzer is able to derive and
display inferred pH (pHCalc) using two contacting conductivity signal boards and the appropriate contacting
conductivity sensors. This method will calculate the
pH of condensate and boiler water from conductivity
and cation conductivity measurements.
l Differential Conductivity: Dual input conductivity
configurations can measure differential conductivity.
The analyzer can be programmed to display dual
conductivity as ratio, % rejection, or % passage.

DESCRIPTION AND SPECIFICATIONS
CONTACTING CONDUCTIVITY (Codes -20 and -30)
Measures conductivity in the range 0 to 600,000 μS/cm
(600mS/cm). Measurement choices are conductivity,
resistivity, total dissolved solids, salinity, and % concentration. The % concentration selection includes the
choice of five common solutions (0-12% NaOH, 0-15%
HCl, 0-20% NaCl, and 0-25% or 96-99.7% H2SO4).
The conductivity concentration algorithms for these
solutions are fully temperature compensated. Three
temperature compensation options are available:
manual slope (X%/°C), high purity water (dilute sodium
chloride), and cation conductivity (dilute hydrochloric
acid). Temperature compensation can be disabled,
allowing the analyzer to display raw conductivity. For
more information concerning the use and operation of
the contacting conductivity sensors, refer to the product

feature uses stored buffer values and their temperature
curves for the most common buffer standards available
worldwide. The analyzer will recognize the value of the
buffer being measured and perform a self stabilization
check on the sensor before completing the calibration.
Manual or automatic temperature compensation is
menu selectable. Change in pH due to process temperature can be compensated using a programmable temperature coefficient. For more information concerning
the use and operation of the pH or ORP sensors, refer

4-20mA Current Input (Codes -23 and -33)
For use with any transmitter or external device that
transmits 4-20mA or 0-20mA current outputs. Typical
uses are for temperature compensation of live measurements (except ORP, turbidity and flow) and for
continuous atmospheric pressure input for determination of partial pressure, needed for compensation of live
dissolved oxygen measurements. External input of
atmospheric pressure for DO measurement allows
continuous partial pressure compensation while the
Model 1056 enclosure is completely sealed. (The
pressure transducer component on the DO board can
only be used for calibration when the case is open to
atmosphere.)
Externally sourced current input is also useful for
calibration of new or existing sensors that require
temperature measurement or atmospheric pressure
inputs (DO only).
For externally sourced temp or pressure compensation,
the user must program the Model 1056 to input the
4-20mA current signal from the external device.
In addition to live continuous compensation of live
measurements, the current input board can also be
used simply to display the measured temperature. or
the calculated partial pressure from the external device.
This feature leverages the large display variables on the
Model 1056 as a convenience for technicians.
Temperature can be displayed in degrees C or degrees
F. Partial pressure can be displayed in inches Hg, mm
Hg, atm (atmospheres), kPa (kiloPascals), bar or mbar.
The current input board can be used with devices that
do not actively power their 4-20mA output signals. The
Model 1056 actively powers to the + and – lines of the
current input board to enable current input from a
4-20mA output device.
Note: this Model 1056 signal input board (-23, -33
model option code) also includes flow measurement
functionality. The signal board, however, must be
configured to measure either mA current input or flow.

3.1 GENERAL
The Model 1056 is easy to wire. It includes removable connectors and slide-out signal input boards. The front
panel is hinged at the bottom. The panel swings down for easy access to the wiring locations.
3.1.1. Removable connectors and signal input boards
Model 1056 uses removable signal input boards and communication boards for ease of wiring and installation. Each of the signal input boards can be partially or completely removed from the enclosure for wiring.
The Model 1056 has three slots for placement of up to two signal input boards and one communication
board.

Slot 3 – Right
Comm. board
Input Board 1
Input Board 2
3.1.2. Signal Input boards
Slots 2 and 3 are for signal input measurement boards. Wire the sensor leads to the measurement board
following the lead locations marked on the board. After wiring the sensor leads to the signal board, carefully slide
the wired board fully into the enclosure slot and take up the excess sensor cable through the cable gland. Tighten
the cable gland nut to secure the cable and ensure a sealed enclosure.
3.1.3. Digital Communication boards
HART and Profibus DP communication boards will be available in the future as options for Model 1056 digital
communication with a host. The HART board supports Bell 202 digital communications over an analog
4-20mA current output. Profibus DP is an open communications protocol which operates over a dedicated
digital line to the host.
3.1.4 Alarm relays
Four alarm relays are supplied with the switching power supply (85 to 265VAC, -03 order code) and the 24VDC
power supply (20-30VDC, -02 order code). All relays can be used for process measurement(s) or temperature.
Any relay can be configured as a fault alarm instead of a process alarm. Each relay can be configured
independently and each can be programmed as an interval timer, typically used to activate pumps or control
valves. As process alarms, alarm logic (high or low activation or USP*) and deadband are user-programmable.
Customer-defined failsafe operation is supported as a programmable menu function to allow all relays to be
energized or not-energized as a default condition upon powering the analyzer.
The USP* alarm can be programmed to activate when the conductivity is within a user-selectable
percentage of the limit. USP alarming is available only when a contacting conductivity measurement board is
installed.
3.2 PREPARING CONDUIT OPENINGS
There are six conduit openings in all configurations of Model 1056. (Note that four of the openings will be fitted
with plugs upon shipment.)
Conduit openings accept 1/2-inch conduit fittings or PG13.5 cable glands. To keep the case watertight, block
unused openings with NEMA 4X or IP65 conduit plugs.
NOTE: Use watertight fittings and hubs that comply with your requirements. Connect the conduit hub to the
conduit before attaching the fitting to the analyzer.

5.4 CONFIGURING AND RANGING THE CURRENT OUTPUTS
5.4.1 Purpose
The Model 1056 accepts inputs from two sensors and
has two analog current outputs. Ranging the outputs
means assigning values to the low (0 or 4 mA) and high
(20 mA) outputs. This section provides a guide for
configuring and ranging the outputs. ALWAYS
CONFIGURE THE OUTPUTS FIRST.
5.4.2 Definitions
1. CURRENT OUTPUTS. The analyzer provides a continuous output current (4-20 mA or 0-20 mA) directly
proportional to the process variable or temperature.
32
The low and high current outputs can be set to any
value.
2. ASSIGNING OUTPUTS. Assign a measurement to
Output 1 or Output 2.
3. DAMPEN. Output dampening smooths out noisy
readings. It also increases the response time of the
output. Output dampening does not affect the
response time of the display.
4. MODE. The current output can be made directly
proportional to the displayed value (linear mode) or
directly proportional to the common logarithm of the
displayed value (log mode).

5.6.1 How the Security Code Works
When entering the correct access code for the
Calibration/Hold security level, the Calibration and
Hold menus are accessible. This allows operators or
technicians to perform routine maintenance. This
security level does not allow access to the Program or
Display menus.
When entering the correct access code for All security
level, the user has access to all menu functions, including Programming, Calibration, Hold and Display.
5.7.1 Purpose
The analyzer output is always proportional to measured
value. To prevent improper operation of systems or
pumps that are controlled directly by the current
output, place the analyzer in hold before removing
the sensor for calibration and maintenance. Be sure
to remove the analyzer from hold once calibration is
complete. During hold, both outputs remain at the last
value. Once in hold, all current outputs remain on
Hold indefinitely.
5.6.2 Procedure.

The Model 1056 automatically recognizes each installed measurement board upon first power-up and each time
the analyzer is powered. Completion of Quick Start screens upon first power up enable measurements, but additional steps may be required to program the analyzer for the desired measurement application. This section covers the following programming and configuration functions;
1. Selecting measurement type or sensor type (all sections)
2. Identifying the preamp location (pH-see Sec. 6.2)
3. Enabling manual temperature correction and entering a reference temperature (all sections)
4. Enabling sample temperature correction and entering temperature correction slope (selected sections)
5. Defining measurement display resolution (pH and amperometric)
6. Defining measurement display units (all sections)
7. Adjusting the input filter to control display and output reading variability or noise (all sections)
8. Selecting a measurement range (conductivity – see Sec’s 6.4, 6.5)
9. Entering a cell constant for a contacting or toroidal sensor (see Sec’s 6.4, 6.5)
10. Entering a temperature element/RTD offset or temperature slope (conductivity-see Sec’s 6.4)
11. Creating an application-specific concentration curve (conductivity-see Sec’s 6.4, 6.5)
12. Enabling automatic pH correction for free chlorine measurement (Sec. 6.6.1)
To fully configure the analyzer for each installed measurement board, you may use the following:
1. Reset Analyzer function to reset factory defaults and configure the measurement board to the desired
measurement. Follow the Reset Analyzer menu (Fig. 5-5) to reconfigure the analyzer to display new
measurements or measurement units.

7.1 CALIBRATION – INTRODUCTION
Calibration is the process of adjusting or standardizing
the analyzer to a lab test or a calibrated laboratory
instrument, or standardizing to some known reference
(such as a commercial buffer).
The auto-recognition feature of the analyzer will enable
the appropriate calibration screens to allow calibration for
any single sensor configuration or dual sensor configuration of the analyzer. Completion of Quick Start upon
first power up enables live measurements but does not
ensure accurate readings in the lab or in process.
Calibration should be performed with each attached
sensor to ensure accurate, repeatable readings.
This section covers the following programming and
configuration functions:
4. Standardization calibration (1-point) for pH, ORP
and Redox (pH Cal - Sec.7.2 and 7.3)
5. Entering the cell constant of a conductivity
sensor (Conductivity Cal - Sec. 7.4 and 7.5)
6. Calibrating the sensor in a conductivity standard
Conductivity Cal - Sec. 7.4 and 7.5)
7. Calibrating the analyzer to a laboratory
instrument (Contacting Conductivity Cal - Sec.7.4)
8. Zeroing an chlorine, oxygen or ozone sensor

9. Calibrating an oxygen sensor in air (Oxygen Cal

7.2.1 DESCRIPTION
New sensors must be calibrated before use. Regular recalibration is also necessary. Use auto calibration instead of manual
calibration. Auto calibration avoids common pitfalls and reduces errors. The analyzer recognizes the buffers and uses
temperature-corrected pH values in the calibration. Once the Model 1056 successfully completes the calibration, it calculates and displays the calibration slope and offset. The slope is reported as the slope at 25°C.

7.2.5 STANDARDIZATION — pH
The pH measured by the Model 1056 analyzer can be
changed to match the reading from a second or referee
instrument. The process of making the two readings
agree is called standardization. During standardization,
the difference between the two pH values is converted
to the equivalent voltage. The voltage, called the reference
offset, is added to all subsequent measured cell voltages
before they are converted to pH. If a standardized sensor
is placed in a buffer solution, the measured pH will differ
from the buffer pH by an amount equivalent to the
standardization offset.

7.4 CONTACTING CONDUCTIVITY CALIBRATION
7.4.1 DESCRIPTION
PLACING A NEW CONDUCTIVITY SENSOR IN SERVICE
New conductivity sensors rarely need calibration. The cell
constant printed on the label is sufficiently accurate for most
applications.
CALIBRATING AN IN-SERVICE CONDUCTIVITY SENSOR
1. After a conductivity sensor has been in service for a period
of time, recalibration may be necessary. There are three
ways to calibrate a sensor.
a. Use a standard instrument and sensor to measure the
conductivity of the process stream. It is not necessary to
remove the sensor from the process piping. The temperature
correction used by the standard instrument may not exactly
match the temperature correction used by the Model 1056.
To avoid errors, turn off temperature correction in both the
analyzer and the standard instrument.
b. Place the sensor in a solution of known conductivity and
make the analyzer reading match the conductivity of the
standard solution. Use this method if the sensor can be easily
removed from the process piping and a standard is
available. Be careful using standard solutions having
conductivity less than 100 µS/cm. Low conductivity standards
are highly susceptible to atmospheric contamination. Avoid
calibrating sensors with 0.01/cm cell constants against
conductivity standards having conductivity greater than 100
µS/cm. The resistance of these solutions may be too low for
an accurate measurement. Calibrate sensors with 0.01/cm
cell constant using method c.
c. To calibrate a 0.01/cm sensor, check it against a standard
instrument and 0.01/cm sensor while both sensors are
measuring water having a conductivity between 5 and 10
µS/cm. To avoid drift caused by absorption of atmospheric
carbon dioxide, saturate the sample with air before making
the measurements.
To ensure adequate flow past the sensor during calibration,
take the sample downstream from the sensor. For best
results, use a flow-through standard cell. If the process
temperature is much different from ambient, keep
connecting lines short and insulate the flow cell.

7.6 CALIBRATION —CHLORINE
With a Chlorine measurement board and the appropriate sensor, Model 1056 can measure any of four variants of
Chlorine:
• Free Chlorine
• Total Chlorine
• Monochloramine
• pH-independent Free Chlorine
The section describes how to calibrate any compatible amperometric chlorine sensor. The following calibration
routines are covered in the family of supported Chlorine sensors:
• Air Cal
• Zero Cal
• In Process Cal
7.6.1 CALIBRATION — FREE CHLORINE
7.6.1.1 DESCRIPTION
A free chlorine sensor generates a current directly proportional to the concentration of free chlorine in the sample. Calibrating the sensor requires exposing it to a solution containing no chlorine (zero standard) and to a solution containing a known amount of chlorine (full-scale standard). The zero calibration is necessary because chlorine sensors, even when no chlorine is in the sample, generate a small current called the residual current. The
analyzer compensates for the residual current by subtracting it from the measured current before converting the
result to a chlorine value. New sensors require zeroing before being placed in service, and sensors should be
zeroed whenever the electrolyte solution is replaced. Either of the following makes a good zero standard:
• Deionized water containing about 500 ppm sodium chloride. Dissolve 0.5 grams (1/8 teaspoonful) of table
salt in 1 liter of water. DO NOT USE DEIONIZED WATER ALONE FOR ZEROING THE SENSOR. THE
CONDUCTIVITY OF THE ZERO WATER MUST BE GREATER THAN 50 μS/cm.
• Tap water known to contain no chlorine. Expose tap water to bright sunlight for at least 24 hours.
The purpose of the In Process calibration is to establish the slope of the calibration curve. Because stable chlorine
standards do not exist, the sensor must be calibrated against a test run on a grab sample of the process liquid.
Several manufacturers offer portable test kits for this purpose. Observe the following precautions when taking
and testing the grab sample.
• Take the grab sample from a point as close to the sensor as possible. Be sure that taking the sample does not alter
the flow of the sample to the sensor. It is best to install the sample tap just downstream from the sensor.
• Chlorine solutions are unstable. Run the test immediately after taking the sample. Try to calibrate the sensor
when the chlorine concentration is at the upper end of the normal operating range.

7.6.2 CALIBRATION — TOTAL CHLORINE
7.6.2.1 DESCRIPTION
Total chlorine is the sum of free and combined chlorine.
The continuous determination of total chlorine requires
two steps. First, the sample flows into a conditioning
system (TCL) where a pump continuously adds acetic
acid and potassium iodide to the sample. The acid
lowers the pH, which allows total chlorine in the sample
to quantitatively oxidize the iodide in the reagent to
iodine. In the second step, the treated sample flows
to the sensor. The sensor is a membrane-covered
amperometric sensor, whose output is proportional to
the concentration of iodine. Because the concentration
of iodine is proportional to the concentration of total
chlorine, the analyzer can be calibrated to read total
chlorine. Because the sensor really measures iodine,
calibrating the sensor requires exposing it to a solution
containing no iodine (zero standard) and to a solution
containing a known amount of iodine (full-scale standard).
The Zero calibration is necessary because the sensor,
even when no iodine is present, generates a small
current called the residual current. The analyzer
compensates for the residual current by subtracting it
from the measured current before converting the result
to a total chlorine value. New sensors require zeroing
before being placed in service, and sensors should be
TABLE 7- 6
Measure
Total Chlorine
zeroed whenever the electrolyte solution is replaced.
The best zero standard is deionized water.
The purpose of the In Process Calibration is to
establish the slope of the calibration curve.
Because stable total chlorine standards do not exist, the
sensor must be calibrated against a test run on a
grab sample of the process liquid. Several manufacturers offer portable test kits for this purpose. Observe
the following
precautions when taking and testing the grab sample:
• Take the grab sample from a point as close as
possible to the inlet of the TCL sample conditioning system.
Be sure that taking the sample does not alter the flow
through the TCL.
• Chlorine solutions are unstable. Run the test immediately after taking the sample. Try to calibrate the sensor
when the chlorine concentration is at the upper end of
the normal operating range.
Note this measurement must be made using the Model
TCL total chlorine sample conditioning system.

7.6.3.1 DESCRIPTION
A monochloramine sensor generates a current directly

to a solution containing no monochloramine (zero
standard) and to a solution containing a known amount
of monochloramine (full-scale standard). The Zero
calibration is necessary because monochloramine
sensors, even when no monochloramine is in the

current by subtracting it from the measured current
before converting the result to a monochloramine value.
New sensors require zeroing before being placed in

The purpose of the In Process calibration is to establish

7.7 CALIBRATION — OXYGEN
7.7.1 DESCRIPTION
Oxygen sensors generate a current directly proportional
to the concentration of dissolved oxygen in the sample.
Calibrating the sensor requires exposing it to a solution
containing no oxygen (zero standard) and to a solution
containing a known amount of oxygen (full-scale
standard). The Zero Calibration is necessary because
oxygen sensors, even when no oxygen is present in the
sample, generate a small current called the residual
current. The analyzer compensates for the residual
current by subtracting it from the measured current
before converting the result to a dissolved oxygen
value. New sensors require zeroing before being placed
in service, and sensors should be zeroed whenever the
electrolyte solution is replaced. The recommended zero
standard is 5% sodium sulfite in water, although
oxygen-free nitrogen can also be used. The Model
499A TrDO sensor, used for the determination of
trace (ppb) oxygen levels, has very low residual
current and does not normally require zeroing. The
residual current in the 499A TrDO sensor is equivalent
to less than 0.5 ppb oxygen.
The purpose of the In Process Calibration is to
establish the slope of the calibration curve. Because the
solubility of atmospheric oxygen in water as a function
of temperature and barometric pressure is well known,
the natural choice for a full-scale standard is air-saturated
water. However, air-saturated water is difficult to
prepare and use, so the universal practice is to use air
for calibration. From the point of view of the oxygen
sensor, air and air-saturated water are identical. The
equivalence comes about because the sensor really
measures the chemical potential of oxygen. Chemical
potential is the force that causes oxygen molecules to
diffuse from the sample into the sensor where they can
be measured. It is also the force that causes oxygen
molecules in air to dissolve in water and to continue to
dissolve until the water is saturated with oxygen. Once
the water is saturated, the chemical potential of oxygen
in the two phases (air and water) is the same.
Oxygen sensors generate a current directly proportional
to the rate at which oxygen molecules diffuse through a
membrane stretched over the end of the sensor. The
92
SECTION 7.0
CALIBRATION
diffusion rate depends on the difference in chemical
potential between oxygen in the sensor and oxygen in
the sample. An electrochemical reaction, which
destroys any oxygen molecules entering the sensor,
keeps the concentration (and the chemical potential) of
oxygen inside the sensor equal to zero. Therefore, the
chemical potential of oxygen in the sample alone determines the diffusion rate and the sensor current.
When the sensor is calibrated, the chemical potential of
oxygen in the standard determines the sensor current.
Whether the sensor is calibrated in air or air-saturated
water is immaterial. The chemical potential of oxygen
is the same in either phase. Normally, to make the
calculation of solubility in common units (like ppm DO)
simpler, it is convenient to use water-saturated air for
calibration. Automatic air calibration is standard. The
user simply exposes the sensor to water-saturated air.
The analyzer monitors the sensor current. When the
current is stable, the analyzer stores the current and
measures the temperature using a temperature element
inside the oxygen sensor. The user must enter the
barometric pressure.
From the temperature the analyzer calculates the
saturation vapor pressure of water. Next, it calculates
the pressure of dry air by subtracting the vapor pressure
from the barometric pressure. Using the fact that dry air
always contains 20.95% oxygen, the analyzer calculates the partial pressure of oxygen. Once the analyzer
knows the partial pressure of oxygen, it uses the
Bunsen coefficient to calculate the equilibrium solubility
of atmospheric oxygen in water at the prevailing temperature. At 25°C and 760 mm Hg, the equilibrium solubility is 8.24 ppm. Often it is too difficult or messy to
remove the sensor from the process liquid for calibration. In this case, the sensor can be calibrated against
a measurement made with a portable laboratory instrument. The laboratory instrument typically uses a membrane-covered amperometric sensor that has been calibrated against water-saturated air.

7.8.1 DESCRIPTION
An ozone sensor generates a current directly
proportional to the concentration of ozone in the sample.
Calibrating the sensor requires exposing it to a solution
containing no ozone (zero standard) and to a solution
containing a known amount of ozone (full-scale
standard). The Zero Calibration is necessary because
ozone sensors, even when no ozone is in the sample,
generate a small current called the residual or zero
current. The analyzer compensates for the residual
current by subtracting it from the measured current
before converting the result to an ozone value. New
sensors require zeroing before being placed in service,
and sensors should be zeroed whenever the electrolyte
solution is replaced. The best zero standard is deionized
water.
against a test run on a grab sample of the process liquid.
Several manufacturers offer portable test kits for this
purpose. Observe the following precautions when taking
and testing the grab sample.
• Take the grab sample from a point as close to the sensor
as possible. Be sure that taking the sample does not
alter the flow of the sample to the sensor. It is best to
install the sample tap just downstream from the sensor.
• Ozone solutions are unstable. Run the test immediately after taking the sample. Try to calibrate the sensor
when the ozone concentration is at the upper end of the
normal operating range.

7.10.2 SLOPE CALIBRATION — Turbidity
This section describes how to conduct a 2-point calibration of the turbidity sensor against a user-prepared
20NTU standard. The calibration requires two steps.
First, immerse the sensor in filtered water having very
low turbidity and measure the sensor output. Next,
increase the turbidity of the filtered water by a known
amount, typically 20 NTU, and measure the sensor
output again. The analyzer takes the two measurements, applies a linearization correction (if necessary),
and calculates the sensitivity. Sensitivity is the sensor
output (in mV) divided by turbidity. A typical new sensor has a sensitivity of about 10 mV/NTU. As the sensor ages, the sensitivity decreases. The figure below
illustrates how turbidity calibration works. Before
beginning the calibration, the analyzer does a dark
current measurement. Dark current is the signal generated by the detector when no light is falling on it. The
analyzer subtracts the dark current from the raw scat98

The turbidity sensor can also be calibrated against a
commercial standard. Stable 20.0 NTU standards are

is not required. Before beginning the calibration, the
analyzer does a dark current measurement. Dark current is the signal generated by the detector even when
no light is falling on it. The analyzer subtracts the dark
current from the raw scattered light signal and converts
