Determining/Setting the cell constants
The cell constants are determined in the control standard, 0.01 mol/l KCl.
You can determine the cell constants of the conductivity measuring cells in
the range of 0.450 ... 0.500 cm
You can also set the cell constants manually in the ranges
0.090 ... 0.110 cm
0.250 ... 2.500 cm
or select the fixed cell constants 0.010 cm
After the calibration, the measuring instrument automatically evaluates the
current status of the calibration. The evaluation appears on the display.

Procedure for determining the cell constants:
Connect a conductivity measuring cell to the measuring instrument.
Press the <CAL> key repeatedly until the
Then press the <RUN/ENTER> key.
Press the <CAL> key repeatedly until the
on the calibration status, the instrument displays:
– the current, calibrated cell constant (with sensor symbol on the
display) or
– the fixed cell constant 0.475 1/cm (without sensor symbol on the
display). In this case, the measurement parameters are initialized.
Note
At this point, the procedure can be terminated with <M>.
Immerse the conductivity measuring cell in the control standard solution,
0.01 mol/l KCI.
