6 Setup with a signal conditioning
instrument
6.1 General information
During setup, the probe must be calibrated with the medium that will
later be measured. To adjust the probe, open the housing cover. You
can select the sensitivity range on the electronics module by means
of the measuring range selection switch.
•
range 1: 0 … 120 pF
•
Range 2: 0 … 600 pF
•
Range 3: 0 … 3000 pF
The adjustment is described in the operating instructions manual of
the respective signal conditioning instrument.

With the measuring range selection switch (1) you can adapt the
sensitivity of the probe to the electrical properties of the measured
medium and the conditions in the vessel. This is necessary to ensure
that the output current range is a big as possible. The resolution of the
probe is thus also correspondingly increased.
Due to this, the probe can for example also detect products with very
low or very high dielectric constant reliably.
•
range 1 (sensitive): 0 … 120 pF
•
range 2 (standard): 0 … 600 pF
•
range 3 (less sensitive): 0 … 3000 pF
