The calibration is now complete. Put the
sensor back in the process and press YES.
The cell constant is automatically updated after the calibration and the new
value can be read on the display as described in section 4.5.
The calculation is as follows: Cell constant in /cm= (Conductivity of calibration solution in mS/cm) x
(Cell resistance in kOhm)
Comparing this calibrated cell constant with the initial nominal cell constant in service code 03 gives a good
indication of the stability of the sensor. If the calibrated cell constant differs more than 20% from the nominal
cell constant error E3 is displayed.
