Fill the vessel e.g. to 10 % and enter 10 % in
the menu "
Min. adjust“ with the "+“ and "–“
keys. Then fill the vessel, e.g. to 80 % or
100 % and enter 80 % or 100 % in the menu
"
Max. adjust“ with the "+“ and "–“ keys. If you
do not know the distance, you have to calcu-
late it by incremental filling.
The indication stops flashing
and the adjustment will be
saved.
You have entered the min. value.

(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 indication at 40 % (3,102 m)
and upper product distance adjustment at
45 % (3.331 m), the measurement will be
inaccurate. A characteristics 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. When the adjustment points are too
close together, small errors multiply to con-
siderably larger errors at the output of the
0 % or the 100 % value.
Adjustment with medium
Setup - Adjustment with VEGAMET or MINICOM
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)
Enter the max. adjustment like the min. ad-
justment with „+“, „–“ or „OK“ (example: 1.270
m).
7. Conditioning/Scaling VEGAMET
Under the menu item " Conditioning/Scaling“
you choose the product distance at 0 % and
at 100 % filling. Then you enter the parameter
and the physical unit as well as the decimal
point.
Enter in the menu window " 0 % corresponds“
the figure of the 0 % filling. In the example of
the adjustment with the PC and the adjust-
ment software VVO this would be 45 for 45 lit-
ers.
