3. Starting up and operating
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.

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.

After 30 seconds, the appliance indicates the measurement reliability of the sensor expressed as a percentage.
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
