5.3 I Calibrati ng the sensors
5.3.1 Calibrati ng the pH sensor (blue)
The pH sensor can be calibrated to 1 point or 2 points (pH 4 and pH 7). 2-point calibrati on is recommended to improve
measurement accuracy.
The setpoints are displayed on the home screen when the appliance is switched on.
Current sensor measurements
• Switch on the appliance.
• Switch off the pool's pump and close the necessary valves in order to isolate the cell and the sensors.

• Select 1- or 2-point calibrati on (2-point calibrati on is recommended):
• Unscrew and remove the pH sensor from the POD.
• Rinse the ti p 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 soluti on and follow the on-screen instructi ons:
• Rinse the ti p 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 soluti on and follow the on-screen instructi ons:
• Once calibrati on is complete, replace the sensor on the POD.
• If calibrati on is unsuccessful, see "8.1 I Appliance behaviour".
1-point calibrati on: possible if the pH 7 and pH 4 soluti ons provided are no longer available.
In order to do this:
- Use a sample of water with a known pH value.
- Acti vate 1-point calibrati on and input this pH value on the screen:
