Setup - Adjustment with the PC on VEGALOG
• Confirm your adjustments with
"OK“ and
you are again in the menu window " Adjust-
ment“.
• Click in the menu window " Adjustment“ to
"
Quit“.
You are again in the menu window " Instru-
ment data parameter adjustment“.
Now the sensor electronics has two charac-
teristics points, one for min. and one for max.,
out of which a linear correlation between
product distance and the percentage filling of
a vessel is generated. Naturally the charac-
teristics point must not be at 0 % and 100 %,
however the distance should be as big as
possible (e.g. at 20 % and at 80 %). The
difference between the characteristics points
for the min./max. adjustment should be at
least 50 mm product distance.
This is a theoretical value, because if the
characteristics points are too close together,
the possible measuring error increases. Ideal
would be, to carry out the adjustment as
shown in the example, at 0 % and at 100 %.In
the menu "
Instrument data/Parameter adjust-
ment/Conditioning/Linearisation“ you can
enter later, if necessary, a correlation be-
tween product distance and percent value of
volume other than linear (see later subitem
linearisation).
Conditioning
• Click in the menu window " Instrument data
parameter adjustment“ to " Conditioning“.
The menu window " Conditioning“ opens.
• Click to "
Scaling“.
In the menu " Scaling“ you enter the actual
0 % and 100 % values of the parameter and
their unit. You thereby inform the sensor, e.g.
that at 0 % filling there are still 45 liters and at
100 % filling 1200 liters in the vessel. The
sensor display then shows with empty vessel
(0 %) 45 liters and with full vessel (100 %)
1200 liters.
