Calibrate the sensor
About sensor calibration
The sensor characteristics slowly shift over time and cause the sensor to lose accuracy. The sensor
must be calibrated regularly to maintain accuracy. The calibration frequency varies with the
application and is best determined by experience.
Temperature calibration
It is recommended to calibrate the temperature sensor once a year. Calibrate the temperature sensor
before calibrating the measurement sensor.
1. Put the sensor in a container of water that is at a known temperature. Under agitation, measure
the temperature of the water with an accurate thermometer or independent instrument.
2. Push the menu key and select SENSOR SETUP>CALIBRATE.
3. If the pass code is enabled in the security menu for the controller, enter the pass code.
4. Select 1 PT TEMP CAL and push enter.
5. The raw temperature value is displayed. Push enter.
6. Enter the correct value if different from that displayed and push enter.
7. Push enter to confirm the calibration. The temperature offset is displayed.
Zero calibration
Because of the stability of the electrode, for most applications this calibration is not required but can
be used to define the unique zero point of the sensor.
1. Remove the sensor from the process and rinse in distilled water.
2. Push the menu key and select SENSOR SETUP>CALIBRATE.

Figure 4 Replace the membrane
Electrode rejuvenation
After some months of operation (3 to 12 depending on sample oxygen concentration, plant shutdown
frequency, etc.), a dark coating of silver bromide (AgBr) may cover part of the silver anode. This
coating does not affect the measurement unless more than 90% of the surface is contaminated.
When changing the electrolyte and membrane, visually check the silver anode. If more than 2/3 of
the surface is coated with silver bromide then an electrode rejuvenation is required. To do this, very
softly polish the areas coated with the deposit using a soft abrasive (N° 400 to 600). After polishing,
rinse with demineralized water and wipe dry with a soft cloth. Some of the dark coloring may be left
to improve sensor stabilization time.
After cleaning, replace the sensor in the sample and leave for 30 minutes for the measurement to
stabilize. Once stable, the sensor must be calibrated.

stabilization or no
stabilization during
calibration in air.
The sample temperature is very different
from the ambient temperature, e.g. 6 °C
(43 °F) in water and 35 °C (95 °F) in air will
cause a measurement drift.

equals the external temperature (use
temperature compensation).
