4.4 I Calibrang the sensors (pH or pH/ORP models)
4.4.1. Choosing the calibraon mode
• The pH sensor and the ORP sensor can be calibrated in "Standard" mode
• The pH sensor can also be calibrated in "Fast" mode
Standard mode (pH & ORP) Fast mode "Fast" (pH) Restart
Calibrate the sensor by
removing it
Calibrate without removing
the sensor
Restart calibraon
4.4.2. Calibrang the pH sensor in "Standard" mode
In “Standard” mode, the pH sensor is calibrated in 2 point calibraon (pH 4 and pH 7) ; 2 point calibraon is recommended
for more accurate measurement.
• Switch o the pool's pump and close the necessary valves in order to isolate the cell and the sensors.
• From the home screen, press 3 mes to access the pH values.
• Press to enter Calibraon mode. The screen displays ("Standard").
• Press to select this mode. The screen displays .
• Remove the sensor.
• Rinse the 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 p of the pH sensor in the pH 7 soluon.
• Wait 15 seconds.
• Press to connue. The screen displays .
• Rinse the 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 p of the pH sensor in the pH 4 soluon.
• Wait 15 seconds.
• Replace the sensor back in its holder.
• Press . Calibraon is complete.
• If necessary, adjust the setpoint (see § “4.4.4. Conguring the pH setpoint”) or press to return to the home
screen.
4.4.3. Calibrang the pH sensor in "Fast" mode
In “Fast” mode, the pH sensor is calibrated in 1 point calibraon ; 1 point calibraon is possible if the pH 7 and pH 4
soluons provided are not available.
• From the home screen, press 3 mes to access the pH values.
• Press to enter Calibraon mode. The screen displays ("Standard").
• Press . The screen displays ("Fast" calibraon mode).
• Press . The second displayed value ashes.
• Place a pH meter in the pool's water then modify this second value with or so that it matches the value
displayed by the pH meter.
• Press to conrm. The current sensor measurement has been replaced.
• If necessary, adjust the setpoint (see § “4.4.4. Conguring the pH setpoint”) or press to return to the home
screen.
