Fig. 79: Calibration of the cell constant
1.
Press and use the or key to move the cursor 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.
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 use the , or keys to set the conductivity value
measured, in accordance with the conductivity value speci‐
fied on the calibration solution.
ð
If calibration has been completed successfully, the con‐
troller stores the determined values for the cell constant
and the error checks relating to the measured value are
restarted. The numerical setting range of the cell con‐
stant is not limited.
6.
Press twice to return to the continuous display.
