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.

As VEGASON 63 is a distance measuring instrument, the distance
from the sensor to the product surface is measured. To have the real
product level displayed, an allocation of the measured distance to the
percentage height must be made. To carry out this adjustment, the
distance is entered with full and empty vessel. If these values are not
known, an adjustment with the distance values, e.g. 10 % and 90 %
is also possible. Starting point for these distance specifications is
always the lower side of the flange, with all other versions the lower
side of the transducer.
The actual level is then calculated on the basis of these entered
values. At the same time, the operating range of the sensor is limited
from maximum range to the requested range.
The real product level during this adjustment is not important, be-
cause the min./max. adjustment is always carried out without chang-
ing the product level. These settings can be made ahead of time
without the instrument having to be installed.
In the main menu item "Basic adjustment", the individual submenu
items should be selected one after the other and provided with the
correct parameter values.
Start your parameter adjustment with the following menu items of the
basic adjustment:
