Since a radar sensor is a distance measuring instrument, the distance
from the sensor to the product surface is measured. For indication of
the real level, an allocation of the measured distance to the percent-
age height must be carried out.
To perform the adjustment, enter the distance with full and empty ves-
sel, see the following example:
100%
0%
0,5 m (19.68
")
5 m
(196.9
")

Fig. 30: Parameter adjustment example min./max. adjustment
1 Min. level = max. meas. distance
2 Max. level = min. meas. distance
If these values are not known, an adjustment with the distances of for
example 10 % and 90 % is possible. Starting point for these distance
specifications is always the seal surface of the thread or flange. By
means of these settings, the real level will be calculated.
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.
Proceed as follows:
1. Select the menu item "Setup" with [->] and confirm with [OK].
Now select with [->] the menu item "Min. adjustment" and confirm
with [OK].
2. Edit the percentage value with [OK] and set the cursor to the
requested position with [->].
