Set-up

Adjustment with the 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
characteristics 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.
adjustment 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

adjustment/Conditioning/Linearisation" you
can enter later if necessary another linear
dependence 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

Conditioning

Conditioning".

The menu window "

Conditioning" opens.

• Click to "

Scaling

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 vessel
1200 litres (100 %).
