Adjustment is only necessary if the measure-
ment is made in gases deviating from air
(CO
2
, He, etc.). When measuring in gases,
sound the distance of the sensor to the prod-
uct surface and enter this in the menu item
"Measurement in gases“. The sensor can
then take the modified (compared to air)
sonic velocity in gases into account and
output correct levels.
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.
Setup
Under the menu item " Adjustment“ you inform
the sensor about the measuring range.
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.
(adjustment independent of the level)

"m“.
Confirm the adjustment with

OK“.
With " +“ and "–“ you adjust the
percentage value for the min.
value (example 0.0 %).
The adjusted percentage
value is written in the sensor
and the distance for the min.
value corresponding to the
percentage value flashes
