Calib Mode - Calibration Of A Ph Sensor - Pentair IntelliPool User Manual

CALIB MODE - Calibration of a pH sensor

Due to its nature, a pH probe needs to be regularly re-calibrated (ideally before the season). If this has been forgotten, a "probe check" message
will appear on the screen of the Control Center. Its service life is approximately 2 years.
For this operation, equip yourself with the pH probe, some DOMOK and the supplied pH4 and pH7 calibration bottles.
Since the pH depends on the temperature, this procedure needs to be performed in the shade (25 °C/77 °F).
1 - Put the switch in Calib. mode (on the back of the indoor display)
2 - Follow the procedure
3 - Dip the end of the pH probe into the pH 7 calibration solution bottle for a minimum of 10 min. A 99-sec countdown is launched.
A - PROCEDURE FAILED: > Check that the pH 7.0 solution is in contact with the probe for the duration of the procedure
4 - Dip the end of the pH probe in the pH 4 calibration solution bottle for a minimum of 10 min. A 99-sec countdown is launched.
5 - The operation has been successful. > Put the switch back in ON mode
