Adjustmentandcommissioning
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.
