VEGASON 54P … 56P

With the "—>" key you change to the 100 %
menu. Enter here the numerical value of your
parameter corresponding to a 100 % filling.
In the example 1200 for 1200 liters.

• Confirm with "

OK".

If necessary, choose a decimal point. How-
ever, note that only max. 4 digits can be
displayed. In the menu "

prop. to", you choose

the physical quantity (mass, volume, dis-
tance…) and in the menu "

Unit" the physical

unit (kg, l, ft

3

, gal, m

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.

5. Conditioning

Under the menu item "

Conditioning", you

assign a product distance at 0 % and at 100
% filling. Then you enter the physical quantity
and the physical unit as well as the decimal
point.

Enter in the menu window "

0 % corresponds"

the numerical value of the 0 % filling. In the
example of the adjustment with the PC and
the adjustment software VVO, this would be
45 for 45 liters.

• Confirm with "

OK".

A linear correlation between the percentage
value of the product distance and percent-
age value of the filling volume is preset. With
the menu "Lin. curve" you can choose be-
tween linear, spherical tank and cylindrical
tank. The generation of a customised
linearisation curve is only possible with the
PC and the adjustment program VVO.

6. Meas. conditions

(see menu schematic)

7. False echo storage

A false echo storage is always useful when
unavoidable false echo sources (e.g. struts)
must be minimised. By creating a false echo
storage, you authorise the sensor electronics
to record the false echoes and save them in
an internal database. The sensor electronics
treats these (false) echoes differently from
the useful echoes and filters them out.
