User programmable means: Switching on a linearization curve
programmed via PC and PACTware
A linearization is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e. g. with a horizontal
cylindrical or spherical tank - and the indication or output of the volume
is required. Corresponding linearization curves are preprogrammed for
these vessels. They represent the correlation between the level
percentage and vessel volume. The linearisation applies to the
measured value indication and the current output. By activating the
appropriate curve, the volume percentage of the vessel is displayed
correctly. If the volume should not be displayed in percent but e.g. in l
or kg, a scaling can be also set in the menu item "Display".
Factory setting is linear.

Caution:
Note the following, if the respective sensor is used as part of an overfill
protection system according to WHG:
If a linearisation curve is selected, the measuring signal is no longer
compulsorily linear proportional to the level. This must be taken into
consideration by the user, particularly when adjusting the switching
point on the level switch.
In the menu item "Sensor-TAG" you edit a 12-digit measurement loop
name. An unambiguous designation can hence be assigned to the
sensor, e.g. the measurement loop name or the tank or product
designation. In digital systems and in the documentation of larger
plants, a singular designation should be entered for exact identification
of individual measuring sites.
The available digits comprise:
l Letters from A … Z
l Numbers from 0 … 9
l Special characters +, -, /, -
Factory setting is "Sensor".
