(if an optional "pH Link" or "Dual Link" module has been installed)
5.3.1 Calibrating the pH sensor (blue)
The pH sensor can be calibrated to 1 point or 2 points (pH 4 and pH 7).
2-point calibration is recommended to improve
measurement accuracy.
The setpoints are displayed on the home screen when the appliance is switched on.
Current sensor measurements
Setpoints
•
Switch on the appliance.
•
Switch off the pool's pump and close the necessary valves in order to isolate the cell and the sensors.
• Press
and
browse the menu using the
buttons.
Press
to confirm.
•
Select 1- or 2-point calibration (2-point calibration is recommended):
•
Unscrew and remove the pH sensor from the POD.
•
Rinse the tip of the sensor with tap water.
•
Shake it to remove any residual water. Do not touch the glass bulb at the end of the pH sensor.
•
Place the pH sensor in the pH 7 solution and follow the on-screen instructions:
•
Rinse the tip of the sensor with tap water.
•
Shake it to remove any residual water. Do not touch the glass bulb at the end of the pH sensor.
•
Place the pH sensor in the pH 4 solution and follow the on-screen instructions:
•
Once calibration is complete, replace the sensor on the POD.
•
If calibration is unsuccessful, see
“8.1 I Appliance behaviour”
.
1-point calibration:
possible if the pH 7 and pH 4 solutions provided are no longer available.
In order to do this:
-
Use a sample of water with a known pH value.
-
Activate 1-point calibration and input this pH value on the screen:
