4.4 I Calibrating the sensors
4.4.1. Choosing the calibration 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)
Calibrate the sensor by
removing it
4.4.2. Calibrating the pH sensor in "Standard" mode
In "Standard" mode, the pH sensor is calibrated in 2 point calibration (pH 4 and pH 7) ; 2 point calibration is recommended
for more accurate measurement.
• Switch off the pool's pump and close the necessary valves in order to isolate the cell and the sensors.
• From the home screen, press
• Press to enter Calibration mode. The screen displays
• Press to select this mode. The screen displays
• Remove the sensor.
• 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 tip of the pH sensor in the pH 7 solution.
• Wait 15 seconds.
• Press to continue. The screen displays
• 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 tip of the pH sensor in the pH 4 solution.
• Wait 15 seconds.
• Replace the sensor back in its holder.
• Press . Calibration is complete.
• If necessary, adjust the setpoint (see § "4.4.4. Configuring the pH setpoint") or press
screen.
4.4.3. Calibrating the pH sensor in "Fast" mode
In "Fast" mode, the pH sensor is calibrated in 1 point calibration ; 1 point calibration is possible if the pH 7 and pH 4
solutions provided are not available.
• From the home screen, press
• Press to enter Calibration mode. The screen displays
• Press . The screen displays
• Press . The second displayed value flashes.
• Place a pH meter in the pool's water then modify this second value with
displayed by the pH meter.
• Press to confirm. The current sensor measurement has been replaced.
• If necessary, adjust the setpoint (see § "4.4.4. Configuring the pH setpoint") or press
screen.
