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.
