Carrying out empty calibration

The empty calibration stores the capacitance value of the probe when the tank is
empty. If the measured capacitance value is, for example, 50 pF (empty calibration), a
switching threshold of 2 pF is added to this value. In this case, the capacitance value
of the switch-point would be 52 pF.
The switching threshold depends on the value set for the switch-point adjustment
→  46.
