4 CALIBRATION MODE
4.1 About Calibration
Calibration should be carried out each time a new electrode is attached to the
controller or when you suspect that the controller/electrode is out of calibration. T he
controller allows you to perform temperature calibration and conductivity calibration.
About Temperature Calibration
It is important to ensure that temperature calibration is carried out prior to
conductivity calibration since temperature readings affect the accuracy of
conductivity measurements. It is recommended that temperature calibration should
be carried out only if the temperature value displayed on t he controller is different
from that of a calibrated thermometer. A temperature offset calibration of ± 10 °C/±
18 °F from the default reading is allowed. Once a temperature calibration is
performed, conductivity calibration should be carried out to ensure the accuracy of
conductivity measurements.
About Measuring Ranges & Conductivity Calibration
The controller has six selectable conductivity measuring ranges. You can only
calibrate one-point in the measuring range th at you have selected for your proces s
application. You have to recalibrate the controller every time you change the
measuring range since the calibration data of the controlle r will be reset every time
a new measuring range is selected.
About Conductivity Calibration
During conductivity calibration, the controller allows a calibration window of ± 40%
from the measured default reading of the calibration standard. The minimum
allowable calibration point is 10% of the full scale reading of the measur ing range
selected.
For best results, select a standard conductivity solution close to the sa mple value
you are measuring.
4.2 Calibration
The controller requires one-point calibration. Conductivity calibration is always
carried out in the specific measuring range selected for the controller. M ake sure,
the controller is set to desired measuring range before you enter cal ibration mode
(Refer Section 5.6 for selecting measuring ranges).
Select a suitable standard conductivity solution so that its conductivity value is
within 10% to 100% of the full scale of the selected measuring range of the
controller. (For better accuracy, select the calibration standard to be nearly 50% of
the full scale of the measuring range selected.) Prepare calibration standard
solution in two beakers – one for rinsing and the other for calibration. Prepare
separate de-ionized water for electrode rinsing.
All new calibration values will automatically override existing calibration data. If you
wish to abort the calibration, press ▲ and ▼ keys simultaneously and the controller
reverts to measurement mode and the controller will revert to previous calibration
data.

Press ENT key to confirm the new cell constant value.
Rinse the electrode in de-ionized water and then rinse with the
calibration standard. Immerse the probe in calibration standard
solution intended for calibration and swirl gently to create a
homogenous sample. Make sure there are no any air-bubbles trapped
in the sensor.

appears in LCD. The ‘READY’ annunciator appears when the reading
is stable.
Once the reading stabilizes press the ▲ or ▼ key to adjust the upper
display value to that of the standard solution. Press the ENT key to
accept the value.
NOTES:
Calibration is completed. The display shows the calibration factor
4
(FCt). This serves as an indication of the effectiveness of the sensor
which will degrade with time and usage. An effective sensor should
have a calibration factor of 0.60 to 1.40
Press ENT key to return to measurement mode.
The acceptable calibration window is ±40% of the
displayed (default) value. For example, if the display is
1000 µS, the values to which it can be adjusted is 600 to
1400 µS.
If the conductivity reading of the solution is not within 10%
to 100% of the full scale of the selected measuring range,
calibration error occurs; LCD displays “ERR” and flash
electrode annunciator.
If the conductivity reading of the solution is beyond the
selected measuring range, calibration error occurs; LCD
displays “Or” (over range), “ERR” and flashes electrode
annunciator.
If calibration error occurs, exit form calibration mode by
pressing ▲ and ▼ keys simultaneously.
NOTES:
• If you use a 2-cell conductivity sensor, make sure that the pin 1 and 2 are
shorted and pin 3 and 4 are shorted on the J10 connector. (Refer section 2 for
more details)
• When calibrating with manual temperature compensation, the controller
automatically changes from the preset process temperature to the calibratio n
temperature. After leaving the Calibration mode, the controller switches back to
the process temperature (for setting the calibration temperature and the
process temperature, see section 5.3)
WARNING: If you change the measuring range of the controll er after calibration is
done, the controller will reset back to its factory default calibration.

5.3 Temperature Settings
Automatic Temperature Compensation (ATC):
The conductivity value of a sample is affected by temperature. Use ATC feature of
the controller to compensate for conductivity changes when the temperat ure of the
sample or process liquid fluctuates. Connect a separate temperature probe
(Pt100/pt1000) to the controller if an integrated conductivity/Temperature probe is
not available.
Manual Temperature Compensation (MTC):
Set the controller to MTC (disable ATC) when the temperature of sample or process
liquid is constant and a temperature probe is not available. If you disable AT C, the
controller allows you to set your process temperature (P.ºC) and calibration
temperature (C.ºC). This allows calibration at a different temperature other than the
process temperature. Example: Setting calibration temperature of 25°C lets you
calibrate using standard solutions at 25°C, even if your process temperature is
different from 25°C.

5.4 Relay 1/Relay 2 Settings
NOTE:
The SP1 settings determine the operating parameters for Relay 1; while SP2
settings define the operating parameters for Relay 2. Since these two settings have
identical setup parameters, only SP1 is described here.
Note that when you change measuring range of the controller, the values you have
set for SP1 & SP2 will not be affected. However, the unit of measurement &
resolution displayed in LCD for SP1 & SP2 will change according to the newly
selected measuring range.
If controller type is set to ‘OFF’ (Refer section 5.5 for controller
settings), the ‘Relay 1/Relay 2 Setting’ is not available.

5.6 Measuring Range Settings
The conductivity controller has 6 different measuring ranges. You need to select a
range which is the most suitable for conductivity reading of your
applications/samples. The factory default is 2000 µS (0 to 2000 µS/cm).
The measuring range you select here will affect the way the control ler behaves in
the measurement mode and calibration mode. In measurement mode, if the
conductivity reading of the controller is above the selected measuring range, the
LCD shows “Or” (over range) error. In calibration mode, the controller adjusts
calibration tolerance based on full scale of the selected measuring range. The
calibration is carried out only for the selected measuring range.
WARNING: If you change the measuring range of the controll er after calibration is
done, the controller will reset back to its factory default calibration.

The relay of the conductivity controller activates when the set-point is reached
(forward direction). In the reverse direction, it does not de-activate when the value
reaches the set-point. Instead, it continues to be active till the value reaches the
amount set by the Hysteresis band.
Example: You have set your high set point at 1900 µS and your hysteresis value at
20 µS. If your measured value overshoots 1900 µS, the controll er’s relay activates.
The actions of the external device will caus e the solutio n’s conductivit y to drop. The
relay will deactivate, when the conductivity value drops below 1880 µS.
