Carrying out empty and full calibration

An empty and full calibration provides the greatest possible operational security. This
is strongly recommended for critical applications.
The empty and full calibration measures the capacitance values of the probes when
the tank is full and when it is empty. For example: if the measured capacitance value
of the empty calibration is 50 pF and that of the full calibration is 100 pF, the average
capacitance value of 75 pF is stored as the switch-point.
Empty calibration
Mak sure that the probe is not covered with the product.
