Particular Cases
If:
• the installation cannot be carried out according to Fig. 7 b,
• the dielectric constant ε
granulate,
then it may be necessary to change the factory-set adjustment.
Adjustment to ε
> 1.6 is possible.
r
For this capacitance calibration, the silo must be empty or the level must be
at least 100 mm below the level of the probe.
The adjuster for the calibration requires approx. 30 turns from one end of
the range to the other.
Please carry out the sequence shown in the diagrams Fig. 19 to Fig. 21.
