7.7 Adjustment
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) and no new
adjustment can be made
or
- if the MET indication and the DIS outputs
relate to height in meters
note the following:
In applications with hydrostatic pressure
transmitters, the adjusted density value must
correspond to the value of the medium.
For the adjustment with medium, two an-
ticipated values for level, pressure etc. cor-
responding to 0 % and 100 % must be
entered.
The menu item "Offset correction“ is activated
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 or strong tight-
ening during mounting.
With the offset correction, the meas. data of
the unpressurised sensor (vessel empty) are
detected as correction values and taken into
account in all subsequent measurements.
