The adjustment with medium corresponds
to the procedure in the reduced menu (see
appropriate chapter).
- if the medium is changed later on (medium
with another density value or DK value)
and no new adjustment can be made
or
- if the MET indication and the DIS outputs
relate to height in meters,
please note the following:
In applications with hydrostatic pressure
transmitters, the adjusted density value must
correspond to the value of the medium. In
applications with capacitive electrodes, the
adjusted DK value must correspond to the
value of the medium (water has a density of
1.0 kg/dm
3 and a DK value of 81.00).
For the adjustment without medium, two
anticipated values for level, gauge, etc.
corresponding to 0% and 100% must be
entered.
The menu item "Offset correction" is opened
when hydrostatic pressure transmitters are
connected. The offset correction should be
carried out after installation of the sensor as
the sensor values can differ slightly due to
different installation positions (vertical or
horizontal installations). With the offset cor-
rection, the meas. data of the unpressurised
sensor (vessel empty) are detected as cor-
rection values and taken into account in all
subsequent measurements.
