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.
