Calibrating the pH probe
→
The original pH probe provided is already calibrated. It is therefore not necessary to calibrate the pH probe when
putting the equipment into service for the first time.
I
However, the pH sensor must be calibrated:
-
at the start of each season when the equipment is re-commissioned,
-
each time the probe is replaced.
1)
Open the pH 7 and pH 10 calibration solutions (use only single-use calibration solutions).
2)
Close the measuring chamber’s 2 supply valves.
3)
If the probe is already installed:
Take the probe out of the measuring chamber, without disconnecting the probe.
If the probe is not already installed:
Connect the probe to the electronics unit.
4)
Go to the ‘
pH Regulation - Calibration
’ menu.
