Indication of the configured
conductivity cell.

The value of a standard calibration
solution is indicated in µS or mS.

The cell constant can be altered in the
range ± 10 % with the
keys:
Keeping the key depressed means
scrolling up or down, starting with the last
digit.
With pressing or

go back to measuring operation.
During calibration or setting of the cell constant a temperature compensation with reference
temperature 25°C is automatically performed. The temperature coefficient of a 0.01 molar
potassium chloride solution according to standard EN 27 888 has been set fixed.
With the keys the cell constant can be altered until
1413 µS/cm
or the next possible value is displayed (1 digit of the cell constant corresponds to a little bit more
than 1 µS/cm).
