5.4.1. Calibrating the ORP probe

I
To ensure an optimal ORP check, it is imperative that the ORP probe is calibrated :
- when first commissioning the equipment.
- at the start of each season when it is commissioned.
- each time the probe is replaced.
1) Turn off the filtration (and therefore the electronics unit).
2) 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.
3) Insert the probe into the ORP 470 mV calibration solution.
4) Wait a few moments, without touching the probe.
5) Turn on the electronics unit.
6) Press and hold down the right-hand key, until the menu
7) Press the top or bottom key x times until menu
8) Confirm by pressing the right-hand key : the message
9) Press on the right-hand key.
10) Wait until one of the messages below is displayed.
11) If the message
a) Press 3 times on the left-hand key : the default display reappears.
b) Rinse the probe under running water.
c) Drain the probe without wiping it.
d) Install the probe into the probe connector.
If the message
a) Press 3 times on the left-hand key : the default display reappears.
b) Visually check the condition of the probe.
c) Try the calibration again, several times if necessary. If the calibration still fails, change the probe and
recalibrate.

5.4.2. ORP measurement adjustment

The adjustment of the ORP measurement requires a measuring device (not supplied) to obtain an actual ORP value.
Prerequisite : the ORP measurement must be between 200 and 900 mV.
Possible settings : from - to + 100 mV compared to the ORP measurement, in steps of 10 mV.
Default setting : ORP measurement.
1) Press and hold down the right-hand key, until the menu
2) Press the top or bottom key x times until menu
3) Confirm by pressing the right-hand key.
4) Select a value with the top/bottom keys.
5) Confirm by pressing the right-hand key.
6) If the message
Press 2 times on the left-hand key : the default display reappears.
The message
a) Press 2 times on the left-hand key : the default display reappears.
b) Visually check the condition of the ORP probe.
c) Try the adjustment again, several times if necessary. If the adjustment still fails, replace the ORP probe and
carry out a calibration of the ORP probe.
