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 100 % in the menu "
Max.
adjust“ with the "+“ and "–“ keys.
4. Conditioning
Under the menu item " Conditioning“ 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 liters.
• Confirm with " OK“.
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.
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 at 40 % (3,102 m) and
upper product distance at 45 % (3.331 m),
the measurement will be inaccurate. A char-
acteristics 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 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.
