The distance indication flashes
and you can choose "feet“ and
"m“.
Confirm the adjustment with
"
OK“.
With " +“ and "–“ you adjust the
percentage value for the min.
value (example 0.0 %).
The entered percentage value
is written in the sensor and the
min. distance value corres-
ponding to that percentage
value flashes.
2. Operating range
Without special adjustment, the operating
range corresponds to the measuring range.
It is generally advantageous to set the oper-
ating range slightly larger (approx. 5 %) than
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
to 1200 liters
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.
