Display of measured value
In this window, the actual measured value is
displayed digitally and as bar graph.
The upper bar shows the current measured
value in percent, pF or scaled in the set unit.
The actual values of the measurement loops
can be displayed from the main menu. Click
to "Display" and then to "Display of measured
value".
Setup
Sensor parameter adjustment – Offset
correction
This function is necessary if an adjustment
should be carried out in m. With this function,
the initial capacitance is saved in the elec-
tronics. A prerequisite is that the electrode is
installed in the vessel and completely
unimmersed.
An offset correction is only necessary if ad-
justment without medium is to be carried out.
For electrodes with concentric tube, this
function is already carried out by VEGA,
since the vessel does not influence the meas-
urement. The offset correction must only be
repeated of the oscillator is exchanged.

eter adjustment" to
