With the "
+
“ or "
–
“ key you can
assign a level distance (exam-
ple 5.85 m) to the previously
adjusted percentage value. If
you do not know the distance,
you have to do a sounding.
The adjusted product dis-
tance is written in the sensor
and the display stops flash-
ing.
You thereby adjusted the lower product dis-
tance as well as the percentage filling value
corresponding to the lower product distance.
Note:
For level detection outside the operating range,
the operating range must be corrected accord-
ingly in the menu "
Sensor optimisation/Opera-
ting range
“.

(max. adjustment)
Now you make the max. adjustment (upper
product distance) (example: 100 % and
1.270 m product distance). First enter the per-
centage value and then the product distance
corresponding to the percentage value.
Note:
The difference between the adjustment val-
ues of the lower product distance and the
upper product distance should be as big as
possible, preferably at 0 % and 100 %. If the
values are very close together, e.g. lower
product distance indication at 40 % (3.102 m)
and upper product distance adjustment at
45 % (3.331 m), the measurement will be
inaccurate. A characteristic curve is gener-
ated from the two points. Even the smallest
deviations between actual product distance
and entered product distance will consider-
ably influence the slope of the characteristic
curve. If the adjustment points are too close
together, small errors inflate to considerably
larger ones when the 0 % or the 100 % value
is outputted.
