cal or spherical tanks - 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 the vessel volume. The linearization applies to the
measured value indication and the current output. By activating the
appropriate curve, the volume percentage of the vessel is correctly
displayed. 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".
The default setting is linear.

Caution:
Note the following, if the respective sensor is used as part of an over-
fill protection system according to WHG:
If a linearization curve is selected, the measuring signal is no longer
linearly proportional to the level. This must be taken into consideration
by the user, particularly when setting the switching point on the limit
signal indicator.
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 des-
ignation. 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:
•
Letters from A … Z
•
Numbers from 0 … 9
•
Special characters +, -, /, -
Factory setting is "Sensor".

The integrated background lighting can be adjusted via the adjust-
ment menu. The function depends on the level of the supply voltage,
see operating instructions of the respective sensor.
In the default setting, the lightning is switched off.
The respective min. and max. measured values are saved in the sen-
sor. The values are displayed in the menu item "Peak values".
