3.6.16. Calibrating the probes : 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 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.
If the probe is not already installed :
Connect the probe to the electronics unit.
4) Turn on the electronics unit.

→ Do not touch the probe.
→ a) Rinse the probe under running water, then leave to drip-dry it without wiping it.
b) Install the probe into the probe holder.
→ Carry out the navigation again with the above instructions, several times if necessary.
If calibration still fails, replace the probe and carry out another calibration.
