The measuring signal can be adjusted with an offset
within a set range between -10 % and +10 %.
Factory setting:
0.0 %

By entering a non-zero value at
TEMP-COR, the tem-
perature compensation function of the instrument
is activated. This allows the specific conductivity to
be automatically calculated and output for a tempe-
rature set under
TEMP-REF, regardless of the actual
temperature of the medium flowing through the CM
flow cell.
Factory settings:
TEMP-REF: 25°C
TEMP-COR: 0.0 %

Use the menus
Factor 1-4 to define up to 4 calibrat-
ion points. Enter the conductivity or the correction
factor for each point to generate the correct cali-
bration function.
Factory settings:
Factor 1: 12 mS/cm, 100%
Factor 2: 111mS/cm, 100%
Factor 3: 211 mS/cm, 100 %
Factor 4: 299 mS/cm, 100%
