However, it is imperative to carry out a calibration of the pH and ORP probes at the beginning of each season
when returning to service, and after each probe replacement.
3.6.17. Calibrating the pH probe
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.
