8.9.2. Calibrating a conductivity sensor

→

Choose the reference solution used in the menu "Parameters -> Mx:Conductivity -> Buffer".

→ Calibrate the conductivity sensor by automatically determining its specific C constant.

8.9.3. Calibrating a pH sensor

• In order not to interrupt the process, activate the HOLD function in the menu "Calibration -> System ->

Hold". The Hold mode is automatically deactivated when the multiCELL restarts after a power interruption,

if the Hold mode was activated at the moment of the power cut-off.

• Before each calibration, correctly clean the electrode with a suitable product.

→ Choose the buffer solution used, in the menu "Parameters -> Mx:pH/ORP -> Buffer". The multiCELL auto-

matically recognizes the pH of the buffer used.

→ Automatically calibrate the pH sensor:

The calibration may fail:

• a possible "warning" message indicates either an error in the buffer solution or the ageing of the probe.

• a possible "error" message indicates that the probe must be replaced.
