The sensor is adjusted via the four keys of the display and adjust-
ment module. The LC display indicates the individual menu items. The
functions of the individual keys are shown in the above illustration.
Approx. 10 minutes after the last pressing of a key, an automatic reset
to measured value indication is triggered. Any values not confirmed
with [OK] will not be saved.
6.4 Setup steps
In HART-Multidrop mode (several sensors on one input) the address
must be set before continuing with the parameter adjustment. You
will find a detailed description in the operating instructions manual
"Display and adjustment module" or in the online help of PACTware
or DTM.

VEGABAR 67 can be used for level as well as for process pressure
measurement. Default setting is level measurement. The mode can be
changed in the adjustment menu.
Depending on the application only the respective subchapter "Level
or process pressure measurement" is of importance. There, you find
the individual adjustment steps.
Level measurement
Set up VEGABAR 67 in the following sequence:
1. Selecting adjustment unit/density unit
2. Carry out a position correction
3. Carry out min. adjustment
4. Carry out max. adjustment
In the menu item "Adjustment unit" you select the physical unit in
which the adjustment should be carried out, e.g. mbar, bar, psi…
The position correction compensates the influence of the mounting
position or static pressure on the measurement. It does not influence
the adjustment values.
