Calibration of the pH probe
The pH probe is submitted to the referential curve which moves in the time, depending on the using of the
pool. For an optimal regulation, it is important to proceed to a calibration each starting of the swimming pool
or changing of the probe.
Before proceeding to a calibration, provide you of pH7 and pH10 standard solutions.
Stop filtering.
Access to the control menu : press 3 seconds on
Select the code «
CA
» using the keys and then valid by . Start to filter.
The screen flashes «
7.0
», the first calibration point.
Dip the pH probe in the pH 7 solution and wait around 2 minutes then valid by .
The displayer will show alternatively 7.0 and – flashing during the calibration (1 to 5 minutes).
If the measured value is correct, the device shows «
Oh
» and then displays the value 10.
Rinse the pH probe in the water and drain it without drying it with a rag.
Insert the pH probe in the pH 10 solution and wait around 2 minutes then valid by .
The displayer will show alternatively 10 and

flashing
during the calibration
(1 to 5 minutes).
If the measured value is correct, the device shows «
Oh
» and then fall over towards the actual display of the
pH.
Note: the probe being in the pH 10, the device flashes 10, because it measures a high pH. The high pH alarm will
disappear from the real measure of the swimming pool.
If one of the values is incorrect, the device shows «
Er
». Your pH probe is not usable anymore (lifespan), to
proceed to its replacement, contact your professional.
