Display of measured value
In this window, the actual measured value is
displayed digitally or as a 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", 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
electronics. A prerequisite is that the
electrode is installed in the vessel and
completely unimmersed.
An offset correction is only necessary if
adjustment 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
measurement. The offset correction must only
be repeated if the oscillator is exchanged.
