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.
(max. adjustment)
The max. adjustment (upper product dis-
tance) is made in the same way (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
adjustment 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 dis-
tance will considerably influence the slope of
the characteristic curve. When the adjust-
ment points are too close together, small
errors multiply to considerably larger errors
at the output of the 0 % or the 100 % value.

(adjustment independent of the actual level)
Key adjustment Display indication
The distance indication flashes
and you can choose "feet" and
"m".
Confirm the adjustment with
"
OK".
Adjustment with MINICOM or VEGAMET
With " +" and "–" you adjust the
percentage value for the min.
value or the lower level (exam-
ple 0.0 %).
The adjusted percentage
value is written in the sensor
and the distance corres-
ponding to the percentage
value flashes.
With the " +" or "–" key you can
assign a level distance (ex-
ample 5.85 m) to the previ-
ously adjusted percentage
value. If you do not know the
distance, you have to do a
sounding.
