GENERAL DESCRIPTION
The Hanna Instruments PCA310, PCA320, PCA330 and PCA340 series of chlorine, pH, ORP and
temperature analyzers are microprocessor controlled, process analyzers which continuously monitor a
sample stream for chlorine content, pH, ORP and temperature values.
The PCA310 - PCA340 monitor the free chlorine or total chlorine in the 0.00 to 5.00 mg/L range
depending on the factory settings and used reagents.
In the DPD Colorimetric method, N, N-Diethyl-p-phenylenediamine indicator and a buffer are mixed
with the sample.
The resulting chemical reaction causes a magenta color to form. The color intensity is proportional to
the concentration of chlorine. The color intensity is measured photometrically (with a light beam and a
photodetector) and converted to chlorine concentration, in mg/L, which is displayed on the front panel.
Indicator and buffer reagent bottles are placed directly into the instrument case. With a sampling period of
5 minutes, reagents need to be replenished about once a month. The reagent bottles are easily visible
through the transparent window allowing the operator to check the reagent levels.
PCA320, PCA330 and PCA340 analyzers use a HI1005 probe to continuously measure the pH of
the sample stream in the range of 0.00 to 14.00 pH. The sample temperature is measured in the
5.0 to 75.0 °C range.
pH and temperature are displayed on the front panel. The pH measurement is temperature corrected.
PCA330 analyzer use HI2008 platinum ORP electrode to continuously measure the sample ORP value.
The pH/temperature combined sensor and the ORP sensor are placed inside the case, directly in the
sample stream.
The case of PCA310 - PCA340 analyzers meet NEMA 4X, 12 and 13 standards. The molded fiberglass
polyester case has outstanding chemical and temperature resistance.
The case provides wall mounting capability and door gasket assures a watertight and dust-tight seal.
The electrical and hydraulic connections are made through the side of the enclosure.
The front cover is secured with two lockable latches.
8
Each chlorine alarm can be enabled or disabled.
Three pH level setpoints can be adjusted by the operator: a dosing setpoint and two alarm setpoints.
The pH control mode is user selectable: on/off or proportional dosing.
The proportional dosing factor (1/∆) is user selectable with a delta between pH 0.1 and 2.0 . The
on/off dosing hysteresis is user selectable between pH 0.05 and 2.00.
pH dosing system controls a SPST relay.
GENERAL DESCRIPTION
Four chlorine level setpoints can be adjusted by the operator: a proportional dosing setpoint, two alarm
setpoints and a minimum level for dosing. The proportional dosing factor (1/∆ is user selectable with
a delta between 0.1 and 5.0 mg/L (ppm)). Chlorine dosing system controls a SPST relay.
Each pH alarm can be enabled or disabled.
For temperature and ORP, two alarm levels can be set by the user.
Each temperature or ORP alarm can be enabled or disabled.
Alarm condition controls a SPDT relay.
A system error feature provides relay activation to signal the need for operator intervention.
System error condition controls a SPST relay.
For PCA310 - PCA330 series the voltage output ranges of 0-10 mV, 0-100 mV, 0-1 V or a current
output of 4-20 or 0-20 mA are available to drive an external device such as a chart recorder.
The analyzer can drive a proportional dosing pump through the 4-20 mA output, for chlorine or for
acid/alkali dosing.
PCA340 has two current outputs of 4-20 or 0-20 mA are available to drive external devices such as
chart recorders.
The analyzer can drive two dosing pumps through the 4-20 mA outputs for chlorine and for
acid/alkali dosing.
The analog output is fully programmable and could be proportional with chlorine concentration, pH,
ORP or temperature value. The limits of the analog output are selectable for each parameter.
The analyzer can store up to 3500 readings (at least 7 days at 3 minutes sampling interval). Stored
history is available to download.
The PCA310 - PCA340 analyzers can be monitored or controlled through RS485 or GSM network
connection.
Errors, alarms and warnings are sent through SMS (using GSM module HI504900).
The analyzer state can be interrogated by a simple call using a GSM phone.

Referring to the drawing on page 11 and the Fluidic Diagram on page 18, the Sample Line is
connected to the instrument at the Sample Port (#18); an internal Regulator (#14) reduces the
inlet pressure from a maximum of 4 bar (57.2 psi) down to 1 bar (14.3 psi); from the Regulator a
PVC tube is connected to the input of the Electrovalve (#22). The output of the Electrovalve goes
to the Measuring Cell (#9). An optional Filter can be installed to the sample port if the stream is
excessively turbid.
The sample coming from the line normally flows through the Measuring Cell (#9). It goes out from
the Measuring Cell through the Drain Tube (#10).
The Measuring Cell is accessible from the capped port placed on the top (#7) for speedy cleaning
and maintenance.
OPERATING DESCRIPTION
CHLORINE MEASUREMENT
SPECIFICATIONS
Drain connection
During the 100 seconds preceding the sampling, the analyzer solenoid input valve is open to allow
sample flow to flush the colorimeter cell. Every 3 to 90 minutes (user selectable), the electrovalve
closes stopping the sample flow and leaving the sample cell full of fresh sample. Cell volume is
controlled by an overflow gateway.
As the sample inlet electrovalve closes, a series of measurements (with LED on and off) of the unreacted
sample is taken to determine an average blank level prior to reagent addition.
The measurement of sample blank signal permits compensation for any turbidity or natural color, and
provides the zero reference point for the measurement.
The two channel Peristaltic Pump (#5) starts rotating dosing a precise quantity of buffer and indicator
(#16 and #17) to enter the colorimeter sample cell. Here a magnetically coupled stirrer mixes the
reagents with the sample.
17
OPERATING DESCRIPTION
After a delay for the color development, a series of measurements (with LED on and off) are taken
(sample level) to determine an average chlorine concentration measurement. The reacted sample
signal is then measured and displayed.
This sequence is repeated every 3 to 90 minutes (user-selectable).
METHOD OF ANALYSIS
Free available chlorine oxidizes the DPD
indicator reagent at a pH between 5.5 and
6.0 to form a magenta-colored compound.
The intensity of the resulting color is proportional to the concentration of chlorine in the
sample. The purpose of the buffer solution
is to maintain the proper pH.
To measure total residual chlorine (free
available chlorine plus combined chlorine) the
PCA adds potassium iodide. The chloramines
in the sample cause iodide ions to become
iodine which then act with free chlorine to
oxidize the DPD indicator. After the chemical
reaction is complete, the optical signal at
555 nm is compared to the signal measured
through the sample (before the reagents
were added). From these measurements total
chlorine concentration is calculated.
pH AND TEMPERATURE MEASUREMENT
The HI1005 pH/temperature probe provides a potential proportional with the pH. The temperature is
measured with Pt100 platinum sensor.
For increased accuracy the pH is corrected for the effects of temperature. Up to 2 buffers can be used
for calibration.
The temperature can be displayed in °C or °F.
The probe can withstand pressure up to 6 bar (87 psi).
ORP MEASUREMENT
The HI2008 probe provides at the out port a potential proportional with the ORP value. The value is
directly displayed in mV. The probe can withstand pressure up to 6 bar (87 psi).
18
LOCATION OF THE INSTRUMENT
Analyzer Location
Locate the analyzer as close as is reasonably possible to the point where the sample is withdrawn
from the product stream (referred to as the sampling point).
The instrument should be mounted indoors, out of direct sunlight. Instrument operating temperature
is 5 to 40 °C (41 to 104 °F).
Sampling Point Location
Locate the sampling point to obtain a representative sample from the product stream. For example,
be sure the sampling point is well downstream from a Chlorine and acid/alkali feed. This ensures that
adequate mixing and reaction of reagents has occurred.
INITIAL PREPARATION AND INSTALLATION
INSTALLATION PERSONNEL
Installation of the PCA310 - PCA340 Chlorine, pH, ORP and temperature analyzers should be
undertaken by persons with technical knowledge of the dangers associated with chemical exposure
and electrical shock.
Hanna Instruments assumes that persons performing the installation tasks are aware of the appropriate
safety procedures.
CAUTION: Review the Material Safety Data Sheets (MSDS) before handling the supplied chemical
reagents.
HYDRAULIC CONNECTIONS
Note: Hydraulic connections should be installed only by qualified personnel to assure conformity
to applicable plumbing codes.
Sample Line Installation
Direct routing of sample lines is recommended.
If the large process pipes are horizontal, taps should be inserted vertically in the middle of the pipe to
avoid pulling sediment from the bottom or air bubbles from the top of the pipe into the sam­ple line.
19
INITIAL PREPARATION AND INSTALLATION
A 1/2 BSP sample input fitting allows direct connection to the optional input filter.
Sample line pressure should be between 0.07 and 4 bar (1 and 57.2 psi) with an ideal pressure of
0.7 bar (10 psi).
It is recommended to assure that the water inlet come at 1 m above the instrument sample input
piping. For maintenance issues is also recommended to install valves on both sampling pipes.
Drain Line Installation
The drain hose fitting is a 20 mm (3/4”) hose barb on the bottom of the instrument enclosure. An air
gap between the end of the drain hose and the drain is recommended to prevent any back flow into
the instrument in the event of drain blockage.
20
INSTALLING THE INPUT FILTER
In order to ensure maximum accuracy of measurements, it is recommended to have always clear
sample, with suspended particles smaller than 0.5 µm. This can be achieved by installing two
filters before the sample input.
The type of filters depends on the quality of the water: the first filter should have 50-100 µm pore
size, whereas in any case the second filter, the one closer to the analyzer, has to be 0.5 µm.
For correct instaling procedure and maintenance, see the instructions of filters.
INITIAL PREPARATION AND INSTALLATION
Return Line Installation
The return hose fitting is a 12 mm (1/2”) hose barb on the bottom of the regulator output port and
should always be connected even when pressure is below 1 bar.
INSTALLING THE pH AND ORP PROBES
To mount the pH and ORP probes, first turn off the analyzer.
Unscrew the closing caps from the electrode holder and remove the protective cap from electrodes and
electrodes connectors.
21
INITIAL PREPARATION AND INSTALLATION
Screw the pH probe (HI1005) in the lower position and the ORP probe (HI2008) in the higher position
and assure that no leakage occurs.
Only after the probe is in final position connect the probe to the dedicated connector. Lock the
connector with the built in nut.
Warning: Never connect or disconnect the probes when the analyzer is powered on.
INSTALLING THE PUMP TUBES
Locate the analyzer reagent tubes in the accessory kit. Each tube is composed of three sections. The
sections are joined together by plastic connectors with plastic collars at the ends of the center section.
Locate the peristaltic pump.
Feed one tube from the shorter end section behind the pump
rollers from the right side of the pump. Seat the plastic collar
at the right end of the center section of tubing into the lower
right notched hole of the pump face.
Grasp the other plastic collar and pull, stretching the center
section, and place the grommet in the lower left notched hole.
Repeat this process with the second pump tube, placing it in the upper notched holes.
Separate reagent caps are provided in the accessory kit. Put the supplied caps onto each reagent bottle
prior to installing them. The tubes inserted in the bottle caps must be placed inside the bottles. The
tubes have different lengths. Attach the longer tube to the bottle in the right side. Ensure the tubes
reach the bottom of the bottles.
22
INITIAL PREPARATION AND INSTALLATION
Place the indicator bottle (HI70450 for free chlorine and HI70460 for total chlorine) on the right and
the buffer bottle (HI70451 for free chlorine and HI70461 for total chlorine) on the left.
Note: Add the content of 5 HI70452 sachets, DPD Compound, to the Indicator Solution prior
to installing it.
Connect the tubes mounted on the bottles to the right side of the pump. The tubing assembly with
“Y” connector has to be mounted between the measuring cell and pump.
The tubes (1, 3) and the “Y” connector (2) are placed on the measuring cell holder (4) in vertical
position. Fix the tubes vertically and insert one by one in the holder. The “Y” connector has to be
positioned below the holder.
ELECTRICAL CONNECTIONS
A power cable (3 mt.) is provided with your analyzer. However, if access to the terminal block is required,
see below.
Warning: Electrical connections should be installed only by qualified personnel to assure
conformity to applicable electrical codes.
Unplug the meter before any electrical connection.
23
INITIAL PREPARATION AND INSTALLATION
Power Connection
Power connections are made at a terminal block located in the center of the electrical compartment to
the right of the fuses.
Hard wiring with 13 mm (1/2”) conduit is recommended and usually required by most municipal
electrical codes.

Alarm Relay
A system alarm feature provides relay activation to signal that the measuring
value exceed the alarm setpoints. The alarm relay is closed (Common connect to
Normal Close) if the value is lower than alarm low setpoint or higher than alarm
high setpoint.
The ALARM LED blinks when alarm is active.
INITIAL PREPARATION AND INSTALLATION
Recorder Output and Relay Access
Hard wiring for alarms and relays recorder output and serial communication can be accomplished
through four watertight connectors on the left side of the enclosure, by passing wires through the
rubber grommet and tightening the nut as described earlier.
Refer to the drawings for proper wire connections.
Note: The Alarm relay is power-fail safe and is closed when the analyzer is not powered.
System Error Relay
A system error feature provides relay activation to signal the need for operator
intervention through an external device, such as a buzzer, a light or any other
electrical equipment. When errors appears, the relay is closed (Common connect to
Normal Close).
The SYSTEM ERROR LED blinks when a system error occurred.
25
INITIAL PREPARATION AND INSTALLATION
If the situation persists for more than a few samples, the operator should notify maintenance personnel
for investigation of the problem.
Note: When the meter is in alarm mode or in system error mode, the user could directly view
the alarm or error description on the display.
If GSM transmitter is installed and GSM mode is selected, the alarms and errors are sent as
SMS message.
The System Error relay is power-fail safe and is closed when the analyzer is not powered.
Chlorine Dosing Relay
The chlorine dosing relay is activated (Common connected to Normal Open) when
chlorine concentration is under the dosing setpoint. The chlorine dosing uses a
proportional algorithm that depends on both, setpoint and delta (∆).
The DOSING CHLORINE LED is turned on when the dosing relay is closed.
Note: The chlorine dosing is stopped when the concentration is over Alarm high setpoint or
when a System Error related to chlorine measurement occurs.
Acid/alkali Dosing Relay
Acid/alkali dosing relay is activated (Common connected to Normal Open) depending
on the setpoint and selected delta. If the analyzer is set to dose acid, the relay
is active when the pH value is over the setpoint. If alkaline is dosed, the relay is
activated when the pH value is under the setpoint.
The DOSING ACID/ALK. LED is turned on when the dosing relay is closed.
Note: The acid/alk dosing is stopped when system error related to pH occurs.
Recorder Output
The recommended recorder hookup uses a twisted pair shielded cable. The shield should be connected
to the terminal at the instrument end and left open at the recorder end.
To operate with this hookup, the following conditions are required at the recorder end:
• The input to the recorder must be isolated from the chassis ground (earth) of the recorder;
• If the recorder has more than one input, they must be differential inputs.
For PCA310, PCA320 and PCA330 several type of outputs are available: 0-10 mV,
0-100 mV, 0-1 V, 0-20 mA or 4-20 mA. The recorder output could be assigned to
Cl, pH, Temperature or ORP.(see the right figure)
26
Proportional dosing pump
At PCA310, PCA320 and PCA330 a proportional dosing pump could be connected
to the 4-20 mA output. The pump could be used to dose chlorine or acid/alkali as
selected by the user. When the output is 4 mA, the pump must be stopped and when the output is
20 mA, the pump must provide the maximum output.
For PCA340 two proportional dosing pumps could be connected to the 4-20 mA outputs. The pump
could be used to dose chlorine and acid/alkali as selected by the user. When the output is 4 mA, the
pump must be stopped and when the output is 20 mA, the pump must provide the maximum output.

the RS485 port.
Note: The RS485 could use also the ground wire to prevent common mode
voltages.
INITIAL PREPARATION AND INSTALLATION
For PCA340 two types of outputs are available: 0-20 mA or 4-20 mA for each output.
The recorder outputs could be assigned to Cl, pH, Temperature.(see the right figure)

The process could be terminated by pressing ESC at any moment.
39
CHLORINE SETTINGS
MEASUREMENT SETTINGS
Select “Chlorine Menu” - “Measure Settings” and set the “Period” between 3 and 90 minutes.
Period (sampling rate) is the elapsed time between two consecutive chlorine measurements. The
sampling rate is also important when the analyzer is used for chlorine dosing. For larger pools, the
period must be longer, and for smaller pools, the period must be shorter.
The sampling rate can be quickly consulted on one chlorine measuring panel.
MEASUREMENT INFO
The analyzer calculates the maximum and minimum concentration value since the first measurement.
The maximum and minimum can be quickly consulted on chlorine measuring panel.
To see information about these values, select “Chlorine Menu” - “Measure Info”. The time stamp
when maximum and minimum appears are also displayed in this menu.
To reset the maximum or minimum values, select the functions “Chlorine Menu”- “Measure Info” “Clear Max. Value”or “Chlorine Menu”- “Measure Info” - “Clear Min. Value”.
Max.Value:0.25 mg/L
Date:04/01/16 22:45
Min.Value:0.00 mg/L
Date:04/01/03 00:16
Clear Max. Value
Clear Min. Value
The maximum (or minimum) value will be set to the current read value.
ANALOG OUTPUT
The type of analog output can be set as described in “Analog output” chapter. The analog output
span for chlorine could be set in “Chlorine Menu” - “Analog Output Cl”.
“Min. Rec” will set the recorder lower limit and “Max. Rec” will set the recorder higher limit.
The Max. Rec. value must be greater than Min. Rec. value.
Max. Rec:5.00 mg/L
Min. Rec:0.00 mg/L
40
CHLORINE SETTINGS
The output will be proportional with chlorine if the read value is between those limits.
Example: For PCA310 - PCA330 if the 0.0 to 1.0 V recorder output has been selected, the operator
can select 0.0 V to correspond to a concentration of 3.00 mg/L (Min. Rec. setting) and 1.0 V to
correspond to a concentration of 4.50 mg/L (Max. Rec. setting).
For PCA340 if the 0.0 to 20.0 mA recorder output has been selected, the operator can select
0.0 mA to correspond to a concentration of 3.00 mg/L (Min. Rec. setting) and 20.0 mA to correspond to
a concentration of 4.50 mg/L (Max. Rec. setting).
The full scale span of the recorder would then be 1.5 mg/L, yielding a magnified view of the
3.00 to 4.50 mg/L concentration range on the recorder.
The analog output limits can be quickly consulted in one of the chlorine measuring panels.
CHLORINE DOSING
The PCA310 - PCA340 analyzers contain a simple proportional dosing algorithm. Proportional dosing
establishes and maintains a controlled and consistent concentration level.
The analyzer has a relay for chlorine dosing and also the 4-20 mA output could be configured as a
dosing output.
Cl
mg/L
Relay off

time
The equation for determining the time for relay on is:
dosing time = (set value - measured value)*Period/Delta
The analog output will have the value:
analog output [mA] = 4 + 16 * dosing time/Period [mA]
Note: If the measured concentration is lower than setpoint minus delta, the dosing will be
continuous until the next measurement is taken (one period).
41
CHLORINE SETTINGS
Example: For setpoint 3.00 mg/L, delta=0.5, sample rate 5 minutes and measured value 2.80 mg/L,
the proportional dosing will be active for the initial 2 minutes and will stop for the remaining 3 minutes.
In fact: Time = (3-2.8)*5/0.5 = 2 minutes
Analog output = 4 + 16*2/5 = 10.4 mA
To modify the dosing setpoint, enter the “Chlorine Menu” - “Dosing control Cl” and edit the “Setpoint”
line. The value must be between 0.10 and 4.90 mg/L.
Setpoint :2.50 mg/L
Delta
:0.1 mg/L
Low Point:0.01 mg/L
Low Point:Inactive
Max. ON :060 min
To modify the Delta, edit the “Delta” line. The available values are 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7,
0.8, 0.9, 1.0, 1.5, 2.0, 3.0, 4.0, 5.0.
Note: The speed of the analyzer could be modified by changing the sampling rate. A new
decision regarding the chlorine regulator is taken only after a new measurement.
The Setpoint and Delta could be quickly consulted on one of the chlorine measuring panels.
Low-reading protection
To prevent excessive chlorine dosing if the detector is not working properly or the reagent bottle is
empty, a “Detector Error” is generated if the measured chlorine value is under the low-point value.
This error is generated only if the low-point feature is set active.
The chlorine dosing is stopped and the SYSTEM ERROR LED starts blinking.
To enable this feature, edit “Chlorine Menu” - “Dosing control Cl” - “Low Point” value and set the
“Low Point” status as “Active”. The allowed value is 0.00 to 1.00 mg/L.
Overdosing protection
To prevent overdosing a “Detector Error” is generated if the dosing command is on for the Max. ON
time and the read value is changing less than 0.05 mg/L.
The chlorine dosing is stopped and the SYSTEM ERROR LED starts blinking. The dosing could be
resumed only by restarting the controller.
To modify this protection, edit “Chlorine Menu” - “Dosing control Cl” - “Max. ON” value. The allowed
range is between 30 and 720 minutes.
42
CHLORINE SETTINGS
ALARMS
Two alarm setpoints are available for chlorine: Alarm high and Alarm low.
The ALARM LED and alarm relay are activated when the chlorine concentration is higher than Alarm-high
or lower than Alarm-low.
To modify the alarm setpoints, enter the “Chlorine Menu” - “Alarms & Err Chlorine” and edit
“Alarm Hi” or “Alarm Lo” value.
The alarms could be separately activated or inactivated.
To modify the alarms status, enter the “Chlorine Menu” - “Alarms & Err Chlorine” menu and edit
“Alarm Hi” or “Alarm Lo” status. When the status is set to “Inactive”, the alarm is ignored.
Note: The Alarm high must be greater than Alarm-low value. The analyzer displays a warning
if the settings are incorrect.
The Alarm-high setpoint and Alarm-low setpoint could be quickly consulted on one of the chlorine
measuring panels. When an alarm is disabled, the —.— is displayed instead of alarm value.

The analyzer has a relay for acid or alkali dosing and also the 4-20 mA output could be configured
as a dosing output.
To select the type of pH dosing edit the “pH Menu” - “Dosing Control pH” - “pH Control” line. The
available options are Proportional and ON/OFF.
pH Control:On/Off
Dosing Type:Acid
Period
:003 sec
Setpoint :07.00 pH
Delta
:0.1
Hysteresis:1.00 pH
Max. ON :060 min
The acid or alkali dosing is set in the “pH Menu” - “Dosing Control pH” - “Dosing Type”. When “Acid”
is selected, the analyzer will dose when the pH value is higher than the setpoint and when “Alk” is
selected, the analyzer will dose when the pH value is lower than the setpoint.
Proportional dosing
The proportional dosing algorithm turns on the dosing relay proportionally with the difference between
the setpoint and measured value.

The analog output will have the value:
analog output [mA] = 4 + 16 * dosing time/Period [mA]
Note: If the measured pH is lower (or higher for acid dosing) than setpoint minus (plus) delta,
the dosing will be continuous until the pH period has elapsed.
To modify the dosing setpoint, enter the “pH Menu” - “Dosing Control pH” edit the “Setpoint”
line. The value must be between pH 2.00 and 12.00. To modify the Delta, edit the “Delta”
line. The available values are 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.5, 2.0. To
modify the dosing time edit the “Period” line.
The allowed values are between 3 and 120 seconds. The period is related only to the dosing
process. The pH measurement takes place with a higher rate.
The speed of the analyzer could be modified by changing the regulator period. A new decision
regarding the pH dosing is taken only after one period has elapsed.
The Setpoint and Delta could be quickly consulted on one of the pH measuring panels.
pH SETTINGS (PCA320, PCA330, PCA340)
The equation for determining the time for relay on is:
dosing time = (set value - measured value)*Period/Delta
ON/OFF dosing
If this mode is selected the “Period” and “Delta” have no effect. The algorithm will use only “Setpoint”
and “Hysteresis”.
For alkaline dosing, the relay will stay on until the pH increases to the setpoint plus hysteresis value,
then the relay stays off until the pH decreases to a value equal to setpoint.

Overdosing protection
To prevent overdosing a “Detector Error” is generated if the dosing command is on for the “Max. ON“
time and the read value is changing less than pH 0.1.
The acid/alkali dosing is stopped and the SYSTEM ERROR LED starts blinking. The dosing could be
resumed only by restarting the controller.
To modify this protection, edit “pH Menu” - “Dosing control pH” - “Max. ON” value. The allowed
range is between 30 and 720 minutes.
ALARMS
Two alarm setpoints are available for pH: Alarm high and Alarm low.
The ALARM LED and relay are activated when the pH value is higher than Alarm high or lower than
Alarm low.
To modify the alarms setpoints, enter the “Alarms pH” menu and edit “Alarm Hi” value or “Alarm
Lo” value.
The alarms can be separately activated or inactivated.
To modify the alarms status, enter the “pH Menu” - “Alarms pH” menu and edit “Alarm Hi” status
or “Alarm Lo” status. When the status is set to “Inactive”, the alarm is ignored.
Note: The Alarm-high value must be greater than Alarm-low value. The analyzer displays a
warning if the settings are incorrect.
The Alarm-high Setpoint and Alarm-low setpoint could be quickly consulted on one of the pH
measuring panels. When an alarm is disabled, the —.— is displayed instead of alarm value.

Buffer pH Cal.
Cal. Date :01/01/01
In this menu the last calibration date is displayed on the “Cal. Date” line. If the probe calibration is
older than 1 month, a warning is displayed.
Initial Preparation
Pour small quantities of pH 7.01 (HI7007) and pH 4.01 (HI7004) or pH 10.01 (HI7010) solutions
into individual beakers. If possible, use plastic beakers to minimize any EMC interference. Also NIST
buffers of pH 6.86 or 9.18 could be used.
For accurate calibration use two different beakers for each buffer solution, the first one for rinsing the
probe and the second one for calibration. By doing this, contamination between buffers is minimized.
Unscrew the probe from its position. Take care to stop the sample flow before removing the probe. If
necessary, disconnect the probe from analyzer to prevent damaging the probe cable.
pH CALIBRATION (PCA320, PCA330, PCA340)
It is recommended to perform pH calibration when the probe is replaced and after any cleaning action.
The analyzer can perform 2 points calibration, 1 point calibration or process pH calibration.
To perform any pH calibration enter in “pH Menu” - “Cal. pH Probe”.
ONE-POINT CALIBRATION
Immerse the pH probe into the buffer solution (e.g. pH 7.01) until the metal ring is
immersed, then stir gently.
Probe
Select the “pH Menu” - “Cal. pH Probe”-“Buffer pH Cal.”.
• The analyzer will prompt to select the first buffer. Select the buffer (e.g. pH 7.01)

Note: If the read value, calculated with the default offset and slope, is different from the expected value
with more than 1.15 pH (i.e. offset > 68 mV), the “Wrong calib. values” message is displayed.
The message “Wrong calib. values” appears also if the pH probe is defective or not connected.
The problem could be identified if the buffer set value is compared with the actual read value
(first and second line of the display).
If the probe is inserted in the appropriate buffer, the measuring cycle is restarted automatically and
message “Wait for stabilize” is displayed again.
If the temperature reading is wrong, the value is set to 25 °C and a blinking “*” is displayed near
it, indicating that is not the real temperature value. The calibration procedure is not interrupted.
When the reading has stabilized, the analyzer displays “Stable... press CFM”.
The analyzer prompts for the second buffer selection, and displays the message “Select buffer
pH... or press SET for one point cal.”.
Pressing SET key will end the one-point calibration procedure.
TWO-POINTS CALIBRATION
• To perform a two-points pH calibration follow the steps described at one-point calibration until the
analyzer displays the message: “Select buffer pH... or press SET for one-point cal.”.
• Immerse the pH electrode into the second buffer solution (e.g. pH 4.01) until the
metal ring is immersed, then stir gently.
Probe
• Press up or down arrow keys to select the second buffer from the list to continue
the calibration and confirm with “CFM”.
pH 4.01
Note: To ensure calibration accuracy, the difference between the first and
second buffer must be more than pH 1. Calibration using pH 7.01 and 6.86
or pH 10.01 and 9.18 is not allowed.
• The analyzer checks for reading’s stability. During this period, the “Wait for stabilize” message
is displayed.
• When the reading has stabilized, the instrument checks if the calculated slope is between
47.3 and 68 mV/pH. If the value is not within this range, the message “Wrong calib. values” is
displayed. In this case it is necessary to perform a cleaning procedure (see “Electrode conditioning
and maintenance” section) or to replace the probe.
• If the value is accepted, the analyzer displays “Stable... press CFM”.
Pressing CFM, completes the two-point calibration.
Cal. Value:06.84 pH
5. Press CFM key when the analyzer prompts for “Overwrite pH cal. ?”.
6. The analyzer checks for reading’s stability (see One-point calibration) and when the value has
stabilised stable the message “Stable... press CFM” is displayed.
7. Pressing CFM key will complete the process pH calibration.
Note: The calibration could be terminated at any time by pressing ESC. In this case the new
calibration is not saved and the old one remains effective.
pH CALIBRATION (PCA320, PCA330, PCA340)
PROCESS pH CALIBRATION
The PCA320, PCA330 and PCA340 have the possibility to calibrate the pH probe without using buffers
and without dismounting the probe. For doing this calibration, a reference pH-meter must be used.
To complete the process calibration, follow the steps:
1. Pour the sample in a beaker. Take the sample directly from the drain port of the measuring cell
(#12) by opening it’s valve (#11) to do this as described in the Calibration Procedure chapter.
2. Place the pH probe of the reference meter in the beaker and stir gently.
3. Wait for the reading to stabilize.
4. Enter in “pH Menu”- “Cal. pH Probe” - “Process pH Cal.” and enter in the “Cal. Value” field the
reading from the reference pH meter.
SET DEFAULT CALIBRATION
When a new probe is connected or for any reason the current calibration is wrong and new
calibration can’t be performed, the default calibration values could be set. In this case the slope is set to
59.16 mV/pH and the offset is set to 0 mV.
To accomplish that, select “pH Menu” - “Cal. pH Probe” - “Set Default pH Cal.”
The analyzer will ask “Reset the pH cal. to default ?” and if CFM key is pressed will replace the existing
calibration coefficients with the default values.

SERIAL COMMUNICATION
The PCA310 - PCA340 have one RS485 serial communication port. The serial communication is
galvanically isolated from other analyzer parts.
RS 485
The connector configuration for RS485 is shown here.
Two working modes are available for the serial communication: STANDARD and GSM.
To set communication as PC type, select “General Menu” - “Serial & GSM Comm.” and set the “Type”
to STANDARD.
To establish connection with the PC the baud rate, the RS485 address and the password must be
matched between the application and PCA310 - PCA340 analyzer.
The baud rate is set in the “General Menu” - “Serial & GSM Comm.” - “Baud Rate” menu. Available
values are 1200, 2400, 4800, 9600 bps.
Analyzer address is set in the “Address” line and could be between 0 and 32.
Note: If several analyzers are connected in a RS485 network, each analyzer must have a unique
address. When one parameter is edited by the user, the PC software is unable to modify it. Any
other parameter can be modified by the PC software.
61
GSM
GSM MODE
If the “Type” is set to GSM, the analyzer will work with HI504900 GSM module. This connection
enables the analyzer to send SMSs to one (or two) cellular phone(s) and through this feature the
device can be monitored. Further, if an error occurs on the PCA3x0, an SMS is sent to the cellular
phone(s) signaling the problem.
When the SMS feature is active, three types of SMS messages are sent to the selected cellular phone(s).
Alarm SMS which contains the Error, Alarm and Warning messages that are active on the analyzer,
separated by “;”. The events that generate the alarm SMS are user selectable from “General Menu”
- “SMS Settings”.
Info SMS which contains the Chlorine, pH, ORP and Temperature readings. Analyzer’s error status and
settings are also included as selected by the user from “General Menu” - “SMS Settings”.
Warning SMS which contains information about the SIM card credit.
The settings related to GSM are grouped in “General Menu” - “Serial & GSM Comm.”.
SETTING THE GSM FEATURE
To use the SMS feature, a SIM card able to make voice calls must be used.
It is necessary to enter the PIN code of the SIM card inserted in the GSM module. To do this, set the
“General Menu” - “Serial & GSM Comm” - “PIN No.”.

GSM
One or two phone numbers associated with the service - to which the messages will be sent – must
be set. The number has to be entered in the fields named “No1” and “No2”. The space reserved for
a phone number is 15 digits.
The phone numbers have to be inserted using the international format excluding the starting +
character and without any space inside the number.
Example: if the cellular number is +39123456789 (+39 is the country code), the number to be
stored in the PCA310 - PCA340 is 39123456789.
The numbers could be activated or inactivated. The SMS is sent only to active numbers. If both numbers
are inactive, no SMS is sent even if both numbers are correctly entered. To activate the phone numbers,
set “Active” in the “Phone1” and “Phone2” fields.
The SMS sending has to be activated by selecting “Active” in the “Send SMS” field. If “Send SMS”
is set to “Inactive” then no SMS will be sent even if the phone numbers are active.
The number of repeated alarm SMSs can be set in the field “RepeatNo”. The range is between 0 and
5. If RepeatNo is set to 0 than only one SMS is sent.
The delay between two repeated SMSs is set in the “Delay” item. The range is between
5 and 60 minutes. If the “RepeatNo” is 0, this parameter has no effect.
GSM CONNECTION
After the correct settings are done, the SMS feature can be enabled by setting “General Menu” - “Serial
& GSM Comm.” - “Type” to GSM.
Note: Power the GSM module before first attempting to connect the analyzer to GSM network.
If the PIN number is wrong, then it is not possible to make the cellular module connection. The
“GSM Wrong PIN Code” message is displayed.
If the first attempt to initialize GSM engine fails because of a wrong PIN, then no other attempt
will be allowed (to prevent sending three wrong PINs).
To make another attempt, a new PIN has to be entered and the analyzer has to be restarted.
The analyzer attempts to initialize the GSM module at startup.
If a wrong PIN was entered three times, the user has to extract the SIM card and manually enter the
PUK number using his own cellular phone to unlock the SIM card.
Note: There is no need to modify the default baud rate (1200) of the serial link when enabling
the GSM feature. It will be switched to 9600 automatically.

SETTING SMS FEATURE
In order to avoid sending frequent SMSs or rapid use of the GSM credit when one measuring channel
does not work correctly, the user can customize his/her SMS sending options.
The options are available in the “General Menu” - “SMS Settings”.
To select the events that generate alarm SMS, set the “Cl Events”, “pH Events”, “ORP Events” or
“Temp. Event” as Active or Inactive. When one of them is active the corresponding alarms and errors
will generate an alarm SMS. When alarm SMS is sent, all current alarms and errors are sent, even if
are not the ones that initiated the SMS.
--Alarms SMS-Cl Events :Inactive
pH Events :Inactive
ORP Events:Inactive
Temp.Event:Inactive
--Info SMS -Set
:Inactive
Errors
:Inactive
To customize the info SMS, two options are available:
• “Errors” - when active, will include in the info SMS all alarms and errors currently active on the
analyzer.
• “Set” - when active, will include in the info SMS alarm and dosing setpoints.
Alarm SMS
When errors or alarms appear, alarm SMS is sent to the active phone numbers. Alarm SMS is sent
without special request. The events that generate alarm SMSs can be selected as described in Setting
SMS Feature paragraph. Alarm SMS is sent once per chlorine cycle.
30 seconds after alarm SMS has been sent, a phone call is made by the analyzer to the programmed
number(s). This is done because the SMSs can be received with a considerable delay due to network
overload, while the phone call takes place immediately.
The phone call advises the user that something has happened on the PCA analyzer and an SMS is
going to be received. Is not necessary to answer the phone call and it is advisable to stop it without
any answer.
A confirmation of the alarm message reception is awaited by the analyzer. The confirmation can be
done by simply calling the PCA analyzer phone number (number of the GSM module). The analyzer will
hang up without answering and will send Info SMS (this confirmation is managed as an information
request; see further on for details). Info SMS don’t need confirmation.
64
GSM
If “RepeatNo” is more than 0, the instrument sends repeated (1 to 5 times) alarm messages if confirmation is not received. This feature prevents loss of message due to phone network being overloaded.
The “0” is associated with no repetition: only one message will be sent and no confirmation awaited.
The delay (5 to 60 minutes) between two subsequent messages can be set on the “Delay” line.
Note: A remote connection will cancel the confirmation awaiting. Also, the analyzer events
occurred during a remote connection will not generate any alarm SMSs, even after the remote
connection ends.
Example of alarm SMS: “Temp Err;L Ph;H Temp;Pwr rst;” (see Errors, Alarms and Warnings
chapter for details).
Info SMS
When the instrument receives a phone call (coming from one of the programmed cellular numbers),
it reads the calling as an information request and reacts by hanging up and sending an info SMS.
The maximum number of characters for an SMS is 160, so, if the message text is longer, many
messages will be sent. In this case a message header is added with information about the message
type and the current / total number of SMSs (for example INF1/2: ).
It is possible to ask the PCA310 - PCA340 for Info SMS from a cellular phone different from the one(s)
set in the analyzer. This is accomplished by sending to the instrument the SMS: “PxxxxAWE”, where
xxxx is the analyzer’s password (the one used for settings).
The instrument will recognize the command and reply by sending the Info SMS.
Note: If the analyzer is waiting for confirmation after sending an alarm SMS, the received
SMS will be just stored on the SIM until the confirmation is received or all the repeated alarm
SMSs are sent.
The info SMS will always contain the Chlorine, pH, ORP and Temperature readings and the Settings
and Errors if enabled. Also, the remaining SMSs number will be added if “Chk. Charge” is active.
Example of info SMS: “Temp Err; L Ph; H Temp; READINGS: ReagRem=8413; Cl=2.05;
pH=7.02; Orp=700; Temp=25.2;”
65
GSM
Example of info SMS (splitted): “INF1/2: Temp Err; L Cl; L Ph; H Temp; Cl Cal; SET: Cl (SP=2.00;
AIH=2.70; AIL=150); pH(SP=7.00; AIH=8.00; AIL=6.00); ORP (AIH=800; AIL=200);
Temp (AIH=30.0; AIL=20.0);”
“INF2/2: READINGS: ReagRem=8413;Cl=1.35;pH=5.02; ORP=280; Temp=75.0;
Remaining SMS=321;”
Warning SMS
The information about SIM charge and expiration date is not saved on the SIM card but is managed
by the network operator; the analyzer can not get the information directly.
To prevent an unnoticed discharge of the SIM card, the user has to configure manually (according
to the credit stored on the SIM card), the maximum number of SMSs that can be sent. The item is
“Remaining” (SMS) in the “General Menu” - “Serial & GSM com.” menu.
If the “General Menu” - “Serial & GSM com.” - “Charge Inf”is set “Active”, every time an SMS
is submitted, the “Remaining” item is updated and will always indicate the remaining number
of messages that the analyzer can send.
With “Chk.Charge” set “Active”, the number of remaining SMSs is checked and when the counter is
going to reach zero, a warning SMS containing the text “Maximum number of SMS reached. Please
check the cellular SIM card charge level” is sent.
Charge Inf:Active
Exp.Date:2010/01/01
Remaining:0000
RepeatNo:2
This particular situation is managed as an error occurrence and a confirmation of the SMS reception
is awaited. After that, a “GSM no credit” warning appears on the display signaling that no other
SMS can be sent.
In this case the user is supposed to extract the SIM card from the cellular module as soon as possible
and check the remaining credit (using its own cellular phone and calling the network operator).
Every time a recharge of the cellular module SIM card is performed, the corresponding expiration
date has to be manually updated – item “Exp.Date” in the “General Menu” - “Serial & GSM com.”.
If the “Chk.Charge” item is set “Active”, a check is performed daily between the current date and the
expiration date. Two weeks before the expiration date, the warning SMS “The cellular SIM card will
expire on: DD-MM-YYYY. Please recharge or substitute it” is sent to the programmed phone number(s).
This message is sent both one week and one day before expiration date.
66
GSM
Note: This particular warning message does not need confirmation.
In this case the user has to recharge or substitute the SIM card. The sending of the repeated
warning messages will be reset when the expiration date is changed. If the expiration date is
reached without any updating of the expiration date, then the message “GSM Card expired” appears on the display and no more SMSs will be sent by the analyzer until the error is deactivated.
To deactivate this error it is necessary to update the SIM expiration date.
If the user has unlimited credit on the SIM card, the “Chk. Charge” must be set “Inactive”.
In this case the value of remaining messages will not be decremented and no check will be
performed on the SIM card expiration date. Moreover, in the info SMS the remaining-messages
information will not be present.
If a problem related to GSM feature occurs during the normal functioning of the analyzer, the
“GSM Not Respond”, “GSM Init failed” or “GSM Network Error” will be displayed and the
analyzer will try repeatedly to initialize the cellular engine. The error will be deactivated only
after a successful initialization.
MODEM CONNECTION
Modem connection can be established between PCA310 - PCA340 and a remote computer. The
connection allows the user to remotely interrogate the analyzer, about its status and measurements
and to change analyzer parameters. Also the log could be downloaded through remote connection.
A SIM card able to receive data calls must be used in HI504900 GSM module.
To enable the answer to data request, the item “Remote” from “General Menu” - “Serial & GSM
com.” must be set to “Active”.
To make the data transfer between PCA310 - PCA340 and remote PC, the HI92500 software must be
installed on the PC, and a modem must be connected between PC and phone line.

The baud rate, the password and the RS485 address must the same on PCA and on PC application.
Note: If the PC stops the communication for 4 minutes, the GSM call is interrupted by the
analyzer to free the line.
67
MAINTENANCE
PCA310 - PCA340 analyzers incorporate several technologies to minimize the maintenance.
Also, if the GSM module is connected, the warnings, alarms and errors are sent to the operator, making
the maintenance even simpler.
The analyzer status could be sent via SMS messages after a call from operator.
Calibration of the chlorine measuring circuits is not normally required. The DPD technique for measuring
chlorine concentration is well established and consistent. Also, by measuring the sample blank absorbency to establish the zero reference of each measurement, the accuracy of the analyzer is assured.
If, for any reason, the Chlorine measurements are inaccurate proceed with the calibration procedure.
A visual check of the hydraulic compartment can detect leaks, pump tubing fatigue or breakage. These
periodic checks help ensure reliable analyzer performance.
PCA310 - PCA340 analyzers warn the user with the “Low reagent” message, when the reagents level
reaches approximately 20%.
Working at maximum capacity (3 minutes sampling rate), the analyzers can operate for 1.5 more days.
The alarm system is based on an internal counter that has to be reset every time the reagents are
replaced.
The counter keeps track of the number of measurements taken and informs the user when it reaches
the 16000th sample with the message “No reagent”.
The pH, ORP and Temperature measurements are done with standard techniques that assure reliability
and accuracy. However if a problem occurs on those measuring channels, an SMS is sent to the user.
Furthermore, if the relation between chlorine, pH and ORP is known for a certain application, one of
those readings could be used to check the others, for example check the chlorine and pH by reading
the ORP values.
ELECTRODE CONDITIONING AND MAINTENANCE
Preparation
Remove the probe protective cap.
Do not be alarmed if any salt deposits are present.
This is normal with probes and they will disappear when rinsed with water.
During transport tiny bubbles of air may have formed inside the glass bulb. The probe cannot function
properly under these conditions. These bubbles can be removed by “shaking down” the probe as you
would do with a glass thermometer.
68
Test measurement
Rinse the probe tip with distilled water.
Immerse the probe in the Hanna Instruments pH buffer 7.01 (HI7007) until the solution is in contact
with the metal ring and stir gently for 30 seconds. The reading must be near pH 7.01. Repeat the
operation for pH 4.01 solution (HI7004). The difference from the previous reading must be near pH 3.
MAINTENANCE
If the bulb and/or junction are dry, soak the probe in HI70300 Storage Solution for at least one hour.
If the probe does not respond to pH changes, electronics may be down and the electrode should be
replaced.
Storage
To minimize clogging and ensure a quick response time, the glass bulb and the junction should be
kept moist and not allowed to dry out. This can be achieved by installing the input lines in such a
way that the probe holder is kept filled with sample.
When not in use, dismount the probe and keep in the protective cap with a few drops of HI70300
Storage Solution or HI7082 (KCl 3.5 M Solution).
Follow the Preparation Procedure before remounting the probes.
Note: Never store the probe in distilled or deionized water.
Periodic maintenance
Inspect the probe and the cable. The cable used for the connection must be intact and there must be
no points of broken insulation on the cable, or cracks on the probe stem or bulb.
Cleaning procedure
General
Soak in Hanna Instruments HI7061 General Cleaning Solution for approximately
1
/2 hour.
Removal of films, dirt or deposits on the membrane/junction:
Protein
Soak in Hanna Instruments HI7073 Protein Cleaning Solution for 15 minutes.
Inorganic
Soak in Hanna Instruments HI7074 Inorganic Cleaning Solution for 15 minutes.
Oil/grease
Rinse with Hanna Instruments HI7077 Oil and Fat Cleaning Solution.
IMPORTANT: After performing any of the cleaning procedures, rinse the probe thoroughly with
distilled water then soak the electrode in HI70300 Storage Solution for at least 1 hour and recalibrate
before reinstalling it.
69
MAINTENANCE
Troubleshooting
Evaluate your probe performance based on the following.
• Noise (Readings fluctuate up and down) could be due to clogged or dirty junction: refer to the
Cleaning Procedure above.
• Dry Membrane/Junction: soak in Storage Solution HI70300 for at least 1 hour. Check to make
sure the installation is such that it forms a well for the probe bulb to constantly remain moist.
• Drifting: soak the probe tip in warm Hanna Instruments Solution HI7082 for one hour and rinse
tip with distilled water.
• Low Slope: refer to the cleaning procedure above.
• No Slope:
- Check the probe for cracks in glass stem or bulb (replace the probe if cracks are found).
- Make sure cable and connections are not damaged.
• Slow Response/Excessive Drift: soak the tip in Hanna Instruments Solution HI7061 for 30 minutes,
rinse thoroughly in distilled water and then follow the Cleaning Procedure above.
• For ORP probe: polish the metal tip with a lightly abrasive paper (paying attention not to scratch
the surface) and wash thoroughly with water.
CHANGING PERISTALTIC PUMP TUBING
It is recommended that the peristaltic pump tubes are changed on a regular basis depending on
sampling period and operating time.
For a 3-5 minutes sample interval and continuous operation, changing of the tubes every month is
recommended. For best results however, change the tubings every time the reagents are replaced.
Note: Rubber gloves and eye protection must be worn while handling reagent tubing to prevent
contact with reagent chemicals. Read MSDS documents before proceeding.
Grasp the plastic collar of one of the pump tubes and pull the fitting away from the pump
toward the front of the case until it clears the retaining indentation.
Then move the fitting sideways, away from the pump until the tube clears the slot.
Release the tube and fitting. The fitting on the other end of the pump tube may now be easily
removed from the pump body.
70
MAINTENANCE
Remove the reagent tubing from one end of the pump tube fitting and pull the pump tube from
behind the pump rollers.
Replace the pump tube with a new one and reassemble in reverse order. Repeat for the other pump tube.
TUBING REPLACEMENT
The remaining tubing in the analyzers should be replaced every two months.
When installing new tubing it is helpful to dip them in hot water before making the connections.
It is also recommended that the tubes are removed and replaced one at a time.
Note: DPD reagent tubing may darken before the scheduled replacement time, but this will
not affect the instruments performance.
71
MAINTENANCE
CLEANING MEASUREMENT CELL
In order to maintain the maximum measurement reliability, it is recommended to periodically clean
the measurement cell. In fact, the measurement cell could collect sediment or develop a film growth
on the inside walls. When the automatic dirt compensation system detects the deposits, the analyzer
will show “Dirty cell” message.
The measurement can continue but cleaning is recommended to avoid deposits that are harder to clean.
Thorough cleaning with a dilute acid solution and a cotton swab is recommended monthly. Depending
on sample conditions at individual locations and absence of input filters, it may be necessary to clean
the cell on a weekly basis. This can be determined by observing the cell condition when reagents
are changed.
It is also highly recommended to clean the cell every time you turn the meter off. By doing this,
scaling and mold growth are prevented. Otherwise, subsequent cleaning might become more difficult.
For cleaning procedure, remove the plastic cap placed on the top of the measuring cell.
Add a few drops of 19.2N Sulfuric Acid solution or alcohol to the cell.
Allow sulfuric acid to stand in the measuring cell for 15 minutes to dissolve any foreign materials
adhering to the cell walls. Wipe the cell interior with a cotton-tipped swab. After wiping, set the
electrovalve to open so that it can start rinsing the cleaning solution from the measuring cell.
CHANGING MEASURMENT CELL
To change the measuring cell (#8 page 11) with a new one (HI704871) in the PCA310 - PCA340
analyzers, follow below listed steps:
1. Stop the analyser by turning off the main switch.
2. Remove the reagent and buffer bottles to free space.
3. Disconnect the reagent and buffer tubes from the cell body.
4. Disconnect the sample inlet tube from the cell body. This tube is between electrovalve (#21 pag
11) and cell.
5. Disconnect the drain tube (#9 on page 11) from the cell.
6. Unplug the cell connector.
7. Unscrew the cell from its support by using hexagonal wrench.
8. Put the new cell in its place and screw it in position. Take care to position the electrical cable first.
9. Reconnect the electrical wires and the pneumatic circuit as it was at the dismounted cell.
10. Power on the PCA310 - PCA340 analyzer.
11. Go to menu mode “Chlorine Menu” - “Cal measuring Cell” and start the “Calibration Blank”
function.
72
MAINTENANCE
• When “Start the blank calibration!” is displayed press the CFM key to confirm.
• Wait for the end of the procedure.
• If the message Press CFM appears, the procedure was successful and pressing CFM will save the
coeficients for the new cell.
• If the message “failed” appears, the cell is not working properly. Check the electrical cable
connection and if the error persists contact your local Hanna Instruments Office.
• Prime the reagent pump - see page 41 for details.
• Wait 3 cycles for the measurement to stabilize.
• Calibrate the measuring cell as described at page 47.
Note: Before start measuring ensure that a stirring bar (HI70486) is present in the cell.
