3. Conditioning
Under the menu item "Conditioning" you can
scale the display, set an integration time and
choose a linearisation curve.
Scaling
Here, you can scale the digital display of the
electrode.
0 % correspond
Here, you enter the value which should be
displayed when 0 % level is reached,
e.g. 20 l.
100 % correspond
Here, you enter the value which should be
displayed when 100 % level is reached, e.g.
1200 l.
If you want the value to be displayed and you
need for the max. value a number with more
than 4 digits, please choose the next higher
unit e.g. 14000 litres = 140 hl.
Decimal point
If necessary, set the position of the decimal
point. Keep in mind that max. 4 digits can be
displayed.
Unit
In the menu "Unit", you choose the physical
unit (%, t, ft
3 , in 3 , gal, in, lb, pF, m, cm, mm, ft,
yd, m 3 , kg, l, hl).
Linearisation curve
In the menu "Lin. curve" you can choose
between three standard linearisation curves.
Preadjusted is a linear dependency between
percentage value of the level and the
percentage value of filling volume.
You can choose between linear, cylindrical
tank, spherical tank and user-programmable
linearisation curve. Programming your own
linearisation curve is only possible with the
PC and the adjustment program VVO. A
user-programmable curve, however, can be
transferred from the PC to the electronics of
the instrument and called up under this menu
item.
Integration time
In the menu item " Integration time", you can
set a delay (in seconds) for the signal output.
4. Outputs
Under the menu " Outputs", you can
determine which parameter should be
outputted by the sensor display and the PA
output.
