Calibrating the pH Measurement

Use the

[Stop] button to switch off system production.

Select

‘Calibrate pH’ in the ‘Operation’ menu and press the

green button with the tick in the message that appears.

A solenoid valve isolates the line with the pH sensor from

the power supply.

Unscrew the pH sensor and carefully dab it dry and clean.

Immerse the sensor in the pH_7 quality buffer.

Press

‘CALIBRATE pH7’ .

‘CALIBRATION IS RUNNING’ appears and, after a short

time, the next menu item.

Remove the pH sensor from the quality buffer and carefully

dab it dry and clean.

Immerse the sensor in the pH_4 quality buffer.

Press

‘CALIBRATE pH4’ .

‘CALIBRATION IS RUNNING’ appears and, after a short

time, a window with the results.

‘Calibration is: not good’ appears, press ‘REPEAT

CALIBRATION’ .

10. If

‘Calibration is: Good’ appears, press ‘END

CALIBRATION’ .

11. Screw the pH sensor in again and only then press

‘RETURN

TO MENU’ - see above!

The water valve opens briefly to keep the sensor moist.
