κ Conductivity
C Concentration
T Constant temperature
1 Measuring range
The characteristic curves received from the measuring
points must increase or decrease very monotonically in
the range of the process conditions, i.e. neither
maximum points, nor minimum points, nor ranges
with a constant behavior can occur. The curve profiles
opposite are therefore not permitted.

Value entry
Enter the three characteristic values for each measured sample in the fields K6 to K8
(value triplets of uncompensated conductivity, temperature and concentration).
• Variable process temperature:
Enter at least the four value triplets needed.
• Constant process temperature:
Enter at least the two value triplets needed.
Please note the following:
If the measured values of the process are outside the range of your sample values, this
considerably reduces the level of accuracy and the error message E078 or E079 will be
displayed. Therefore, take the limit values of your process into consideration when
determining the characteristic curves. Wird bei aufsteigender
If you enter an additional value triplet of 0 μS/cm and 0% for every temperature used
when the characteristic curve is increasing, you can work from the start of the measuring
range with sufficient accuracy and without an error message.
Enter the values in order of increasing concentration (see the following example).
