3.7.10. Calibrating the pH probe

→ The original pH probe is already calibrated. It is therefore not necessary to carry out calibration when putting the
equipment into service for the first time.
I
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.
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 «.Ca.» menu : the message « 7.0 » flashes.
6) Insert the probe into the pH 7 calibration solution, then wait a few minutes.
7) Press on OK : do not touch the probe, and wait until the message « 10 » flashes.
8) Rinse the probe under running water, then leave to drip-dry it without wiping it.
9) Insert the probe into the pH 10 calibration solution, then wait a few minutes.
10) Press on OK : do not touch the probe, and wait until you get one of the displays shown below.
11) 2 possibilities :
• The message « X » appears :
The calibration has failed. Press on OK, then carry out a new calibration, several times if necessary. If
calibration still fails, replace the probe and carry out another calibration.
• The message «
The calibration was successful.
a) Rinse the probe under running water, then leave to drip-dry it without wiping it.
b) Install the probe into the probe holder.
c) Press on OK.
