2. Calibration for internals with a partially filled silo,
so that a calibration can also be carried out if the probe is partially covered and
has been shortened.

The Levelflex is now calibrated.
Checking measurement reliability:
The strength of the signal can be checked after the silo has been filled. Go to field V3H2. If a value >= 3 is shown here then measurement is assured over
a long period of time. With very shortened probes, the value for the blocking distance should be checked in field V3H8 and compared with the measuring
range to ensure that the blocking distance lies outside the measuring range.
