3.1 Calibration procedure
The sensor must be calibrated when your pH Perfect is first installed and ideally
every two months there after to obtain the best operating conditions.
Calibration must be done each time your pool is restarted at the beginning of the season.
The calibration procedure is carried out when filtration is stopped thanks to its double supply (the
appliance remains powered on). Before calibrating, stop filtration and close the valves so as to isolate
the pH sensor holder from flowing water.
Procedure
1. Fill a bottle with clean water(tap water).
2. Undo the sensor holder and remove the sensor from the pipe.
3. Rinse the sensor in the bottle. Then shake gently to remove excess water.
4. Pour a small amount of pH 7.5 calibration fluid into a small bottle (enough to cover the end of the
sensor tip). Then immerse the sensor into the fluid. Discard the used calibration fluid after use so as
not to contaminate the rest of the bottle.

To finish calibration, press the “CAL” button.
The instrument will return to measuring mode.
Once the calibration is complete install the
sensor in the location provided in the POD
Keep the “CAL/Enter” button
pressed for more than 5
seconds until “Calibration”
appears on the LCD screen (5a).
Press the “CAL/Enter” button
again as indicated on the screen
for calibration on pH7 (5b).
an automatic progression bar
then appears (5c). Keep the
sensor immersed in the buffer
solution for 30 seconds.
