VEGASON 51 V … 53 V 79
Set-up - Adjustment with PC on VEGALOG
• Confirm the adjustments with "OK", and you
are again in the menu window " Adjustment".
• Click in the menu window "Adjustment" to
"Quit".
You are now again in the menu window " In-
strument data parameter adjustment".
Hence the sensor electronics has two char-
acteristics points, one at MIN and one at
MAX, out of which a linear proportionality
between level distance and the percentage
filling of a vessel is generated.
The characteristics points however must not
be at 0 % and 100 % however the difference
should be as large as possible (e.g. at 20 %
and at 80 %). The min. distance between the
characteristics points for the min./max. ad-
justment should be 50 mm.
When the characteristics points are too close
together, the possible meas. error increases.
It is hence suitable when you carry out the
adjustment at 0 % and at 100 %.
In the menu " Instrument data/Parameter ad-
justment/Conditioning/Linearisation" you can
enter later if necessary another linear de-
pendence between the level distance and the
percentage filling degree (see later subpoint
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. Hence you inform the sensor, e.g. that at
0 % filling there are still 45,5 litres and at
100 % filling1200 litres in the vessel.
The sensor indication shows in case of empty
vessel 45,5 litres (0 %) and in case of full ves-
sel 1200 litres (100 %).
