• Choose in the following window if you want

to make the adjustment in meters (m) or in
feet (ft).

• Enter a distance

In the example the 0 % filling is at a product
distance of 3,400 m and the 100 % filling at a
product distance of 0,500 m.

Note:

Note:
The sensor can only detect levels within the
defined operating range. For level detection
outside the operating range, the operating
range must be corrected appropriately in the
menu "Sensor optimisation/Meas.
environment" on page 55/56.

ment data parameter adjustment".

Hence the sensor electronics has two
characteristics points (MIN and MAX), out of
which a linear proportionality between
product distance and the percentage filling of
a vessel is generated.
However the characteristics points must not
be at 0 % and 100 % but the difference
should be as large as possible (e.g. at 20 %
and at 80 %). The min. product distance of
the characteristics point for min./max.
adjustment should be 50 mm. When the
characteristics points are too close together,
the possible meas. error increases.
It is hence suitable to carry out the
adjustment at 0 % and at 100 %.

In the menu

"Instrument data/Parameter

adjustment/Conditioning/Linearisation" you
can adjust later another linear dependence
between product distance and the
percentage filling degree (see later subpoint
linearisation).
