the entire measurement will then be longer and the sensor will react
to measured value changes with a delay. In general, a period of a few
seconds is sufficient to smooth the measured value display.

settings and jump to the next menu item with the [->] key.
A linearisation is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. in a horizontal cylindri-
cal or spherical tank - and the indication or output of the volume is
required. Corresponding linearisation curves are preprogrammed for
these vessels. They represent the correlation between the level per-
centage and vessel volume. 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".

Caution:
Note the following if the VEGAPULS 63 with corresponding approval
is used as part of an overfill protection system according to WHG
(Water Resources Act):
If a linearisation curve is selected, the measuring signal is no longer
necessarily linear to the filling height. This must be considered by the
user especially when setting the switching point on the limit signal
transmitter.
In this menu item you can enter an unambiguous designation for 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 points.

With this menu item, the Basic adjustment is finished and you can
now jump to the main menu with the [ESC] key.
In the menu item "Display" you can define how the measured value
should be presented on the display.
