Adjustment and commissioning

The multiCELL associates the two calibrated values to the range of the selected

analogue input signal (slope and offset).

→ Immerse the probe of the sensor (for insatne a pH sensor) in the first buffer

solution: the multiCELL displays the solution measured value.

→ Enter the value of the buffer solution (indicated on the bottle).

→ Wait until the measured value stabilises.
