4.4 I Calibrating the sensors
(pH or pH/ORP models)
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)
Fast mode "Fast" (pH)
Restart
Calibrate the sensor by
removing it
Calibrate without removing
the sensor
Restart calibration
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
3 times to access the pH values.
•
Press
to enter
Calibration
mode. The screen displays
("Standard")
.
•
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
to return to the home
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
3 times to access the pH values.
•
Press
to enter
Calibration
mode. The screen displays
("Standard").
•
Press
. The screen displays
("Fast" calibration mode).
•
Press
. The second displayed value flashes.
•
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 confirm. The current sensor measurement has been replaced.
•
If necessary, adjust the setpoint (see § “4.4.4. Configuring the pH setpoint”) or press
to return to the home
screen.
