Calibration procedure

Refer to paragraph 4.2. to change the language.
!
Important:
The sensor must be calibrated when your pH Perfect is first installed and
ideally every two months there after.
> Calibration must be done each time your pool is restarted at the beginning of
the season.
> The procedure should be repeated if an abnormal amount of corrective solution
is consumed (pH minus or pH plus).
> The calibration procedure can only be carried out when filtration is stopped.
> Before calibrating, stop filtration and close the valves so as to isolate the pH
sensor holder from flowing water.
2
> Undo the sensor holder and
remove the sensor from the pipe.
