Calibration of the pH probe
The supplied pH probe is already calibrated. It is therefore not necessary to calibrate the pH probe when the
equipment is put into service for the first time.
I
However, in order to ensure optimal pH regulation, it is imperative to calibrate the pH probe at the start of
each season when putting back into service, and after each replacement of the probe.
1)
Switch off the filtration (and therefore the electronics box).
2)
Open the standard solutions pH 7 and pH 10 (use only single-use standard solutions).
3)
If the probe is already installed :
a) Extract the probe from the probe holder, without disconnecting it.
b)
Remove the nut from the probe holder and replace it with the plug provided.
If the probe is not yet installed :
Connect the probe to the electronics box.
4)
Switch on the electronics box.
5)
Make a long press on the right key until the message flashes.
6)
Press the up or down key x times until the message flashes.
7)
Press the right key to validate : the message flashes.
8)
Insert the probe into the pH 7 standard solution, then wait a few minutes.
9)
Press the right key : the display below appears.
Do not touch the probe during this time, and wait until you get one of the displays below.
10)
2 Possibilities :
The message flashes. In this case, go to step
11
.
The message is displayed : calibration failed. To acknowledge this display, press the left key.
In this case, visually check the condition of the probe, then attempt the calibration again, several times if
necessary. If the calibration still fails, change the probe and recalibrate.
11)
Insert the probe into the pH 10 standard solution, then wait a few minutes.
12)
Press the right key : the display below appears.
Do not touch the probe during this time, and wait until you get one of the displays below.
13)
2 Possibilities :
The message is displayed briefly, then the message flashes. Calibration is complete.
The message is displayed : calibration failed. In this case, visually check the condition of the probe, then
attempt the calibration again, several times if necessary. If the calibration still fails, change the probe and
recalibrate.
To acknowledge these displays, press the left key twice : the default display appears.
I
The pH 7 and pH 10 standard solutions are for single use. To avoid handling errors, discard these solutions
after use.
