10.3.1 Determining the cell constant (calibration)
Proceed as follows to determine the cell constant:
1 Connect a conductivity measuring cell to the meter.
2 Select the channel of the measuring cell in the measured value
display.
3 If necessary, select the parameter, conductivity with <MODE>.
4 Start the calibration with <CAL>.
The calibration display appears.
5 Immerse the conductivity measuring cell in the control standard
solution, 0.01 mol/l KCI.
6 Start the measurement with [OK].
The measured value is checked for stability (Stability control).
7 Wait for the end of the measurement with Stability control or
accept the calibration value with [OK].
The cell constant determined is displayed.
8 Accept the new calibration values with [OK].
The calibration record is displayed and output to the interface.
The calibration procedure is finished.
or
To switch to the measured value display without accepting the
new calibration values, press <ESC>.
