VEGA VEGAPULS 62 (≥ 2.0.0 - ≥ 4.0.0) Profibus PA Approval according to LPR radio standard - Manual (Page 47)

A linearization is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. in 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.
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
"D
isplay".
Enter the requested parameters via the appropriate keys, save your
settings and jump to the next menu item with the [ESC] and [->] key.
Caution:
Note the following if the instrument with corresponding approval 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.
When a reset is carried out, all settings (with only a few exceptions) are
reset. The exceptions are: PIN, language, lighting, SIL and HART
mode.
The following reset functions are available:
l Delivery status: Restoring the parameter settings at the time of
shipment from the factory incl. the order-specific settings. A
created false signal suppression, user-programmable linearization
curve, measured value memory as well as event memory will be
deleted.
