Carrying out full calibration

The full calibration measures the capacitance value of the probe when the tank is full.
If the measured capacitance value is, for example, 100 pF (full calibration), a
switching threshold of 2 pF is subtracted from this value. The capacitance value of the
switch-point is thus 98 pF.
The switching threshold depends on the value set for the switch-point adjustment
→  46.
Make sure that the probe is covered by the medium up to the desired switch-point.
