The entered percentage value
is written in the sensor and the
min. distance value corres-
ponding to that percentage

2. Operating range
Without special adjustment, the operating
range corresponds to the measuring range.
Generally, it is useful to choose a slightly
wider range (approx. 5 %) for the operating
range than for the measuring range.
Example:
Min./max. adjustment: 1.270 … 5.850 m;
adjust operating range to approx.
1.000 … 6.000 m.

100 % (1.270 m) correspond

Span (4.58 m)
0 % (5.850 m) corresponds
to 45 liters
Under the menu item "
Adjustment“ you inform
the sensor of the measuring range it should
operate in.
You can carry out the adjustment with or
without medium. Generally, you will carry out
the adjustment without medium, as you can
then adjust without a filling/emptying cycle.
