G.4.4. Calibrating the pH probe
Important advance information
The original pH probe is already calibrated. It is therefore not necessary to carry out calibration of the pH probe
when putting the equipment into service for the first time.
However, it is imperative to carry out a calibration of the pH probe at the beginning of each
season when returning to service, and after each probe replacement.
1)
Open the pH 7 and pH 10 calibration solutions (use only single-use calibration solutions).
2)
Turn off the filtration (and therefore the electronics unit).
3) If the probe is already installed :
a)
Remove the probe from the probe holder, without disconnecting it.
b)
Remove the probe holder nut and replace it with the stopper supplied.
If the probe is not already installed :
Connect the probe to the electronics unit.
4)
Turn on the electronics unit.
5)
Go to the «
pH Regulation - Calibration
» menu.
