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 measure it by
sounding.
The entered product distance
is written in the sensor and the
display stops flashing.
You thereby adjusted the lower product dis-
tance as well as the percentage filling value
corresponding to the lower product distance.

(max. adjustment)
Enter the max. adjustment (upper product
distance) in the same manner (example:
100 % and 1.270 m).
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 adjustment at 40 %
(3.102 m) and upper product distance ad-
justment at 45 % (3.331 m), the measurement
will be inaccurate. A characteristics curve is
generated from the two points. Even the
smallest deviations between actual product
distance and entered product distance will
considerably influence the slope of the char-
acteristics curve. If the adjustment points are
too close together, small errors inflate to
considerably larger ones when the 100 % or
the 0 % value is outputted.

The distance indication flashes
and you can choose "feet" and
"m".
Confirm the setting with "
OK".
With "
+" and "–" you set the
percentage value for the min.
value or the lower level (exam-
ple 0.0 %).
The entered percentage value
is written in the sensor and the
distance corresponding to the
percentage value begins
flashing.
