Carrying out full calibration
!
Note!
• 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 (for more
information, see
ä
59).
To carry out a full calibration, proceed as follows:
1.
Make sure that the probe is covered by the medium up to the desired switch point.
2.
Turn the function switch to position 2.
3.
Press the "+" key for at least two seconds.
4.
Release the "+" key when the green LED 5 starts to flash.
The process of saving the full calibration is complete when the green LED 5 lights up continuously.
You can turn the function switch back to position 1 to return to operation.

** Switch status signaling (on/off/flashing) depends on the mounting location selected and the failsafe mode (MIN/MAX) set.
The LED flashes if a calibration has not yet been carried out.
