Calibration compared to a calibration solu‐
tion
1.
Press and move the cursor using the or key to
[CELLCONST]
and confirm
with
.
2. Enter the temperature coefficient of the calibration solution.
The temperature coefficient of the calibration solution is specified on the
storage tank for the calibration solution. ProMinent's calibration solution has a
temperature coefficient of 2% /K.
Confirm with .
3. Now dip the sensor into the calibration solution and gently move the sensor.
4. Wait until the conductivity and temperature measured value has stabilised.
Press
.
ð
The conductivity value measured is displayed.
5.
Now enter the conductivity value measured using the , or keys, in accord‐
ance with the conductivity value specified on the calibration solution.
ð
If calibration has been completed successfully, the controller stores the deter‐
mined values for the cell constant and the error checks relating to the meas‐
ured value are restarted. The numerical setting range of the cell constant is
not limited.
6.
