12.4.6 Temperature coefficient
This menu is used for displaying and setting the
temperature coefficient.
Because different measuring fluids have different
temperature coefficients, the appropriate coefficient
must be set. The setting range is 0.0 to 8.0 % / °C.
The factory setting is 2.5 % / °C, which is suitable for
many applications.

Temper. coeff.
1. Press the [Right] button to open the
"Temper. coeff." menu.
Temper. coeff.
0.0 % / °C
2. Press the [Right] button to open the value input
display.
3. Press the [Up] and [Down] buttons to set the
value.
12.4.7 Cell constant C
The mechanical dimensions used for the
measurement of active surfaces of the measuring
cell are defined in the cell constant. The measuring
cell is characterised by the cell constant.
1. Press the [Right] button to open the "Cell const."
menu.
Cell const.
0.050
2. Press the [Right] button to open the value input
display.
3. Press the [Up] and [Down] buttons to set the
value.

Cable compensation (only for conductive
measurement)
The capacity of the cable can lead to an incorrect
value, particularly for small measuring ranges.
This incorrect value can be corrected as follows:
1. Press the [Right] button to select the "Cable
compens." menu.
2. Hold the connected, dry measuring cell in the air.
– If the top line of the display reads a measured
value, i.e. the value 0.00 is not displayed,
cable compensation must be performed.
0.00 μS
Press
3. Simultaneously press the [Left] and [Down]
buttons.
– If the compensation is successful, the value
0.00 is displayed.
12.4.8 Measuring range
In this menu, the required measuring range for the
device can be set (MΩ, μS, mS).
1. Press the [Right] button to open the
"Measur. range" menu.
2. Press the [Right] button (several times) to select
a measuring range.
Measur. range
2.000 μS
Measur. range
20.00 MOhm
When setting the measuring range, ensure
that it is suitable for the cell constant of the
Note
measuring cell. See section
