Switchpoint covered -> uncovered
Explanation of switchpoints:
Capacitance
A Capacitance uncovered probe
C Switchpoint covered -> uncovered (Menu item K)
D Hysteresis (Menu item L)
E Switchpoint uncovered -> covered
F Capacitance covered probe
Factory setting is lowest pF value (3 pF).
Resolution is 0.1 pF (<100 pF) or 0.5 pF (>100 pF). If values are >100 pF, a dot behind the number
means 0.5 pF (e.g. 100. means 100.5 pF)

pF
Hysteresis
Hysteresis can be adjusted if unstable capacitance is present with covered probe (e.g. moving liquid
surface with vertical mounting) to avoid nervous switching of signal output.
Minimum value (= factory setting) is 0.5/ 0.2 pF (for Low/ High sensitivity) .
Maximum value is limited by the max. measurable capacitance.
Resolution see "Switchpoint covered -> uncovered".
Diagnostics
M. ON *
OFF
Auto Function Test
The unit allows to permanently auto test the internal electronics. The test runs in the background and
does not influence the functionaly of the measurement.
If a failure is detected, the display states "ERR", the red LED is on and the relais is set to de-
energized. Electronic is defect and must be changed.

Lock code
The Lock code can be set to protect entering in any Menu or doing a Push Button Calibration or a
Manual Function Test.
Any number from 1 to 999 can be set.
With setting "000" the Lock Code is not active (factory setting).
If a Lock code was set and forgotten, call manufacturer to get the release code.

YES
Factory reset
First all parameters will be reset to factory settings (as stated with an "
*
").
Second the unit will automatically start a new calibration.
