VEGA VEGAPULS 61 (≥ 2.0.0 - ≥ 4.0.0) 4 … 20 mA_HART four-wire Approval according to LPR radio standard - Manual (Page 45)

The menu item "Extend" is used to extend an already created false
signal suppression. This is useful if a false signal suppression was
carried out with a too high level and not all false signals could be
detected. When selecting "Extend", the distance to the product surface
of the created false signal suppression is displayed. This value can
now be changed and the false signal suppression can be extended to
this range.
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 "Display".
Enter the requested parameters via the appropriate keys, save your
settings and jump to the next menu item with the [ESC] and [->] key.
With a reset, certain parameter adjustments carried out by the user are
reset.
The following reset functions are available:
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 as
well as the measured value memory will be deleted.
Basic settings: Resetting the parameter settings incl. special and
laboratory parameters to the default values of the respective instru-
ment. A created false signal suppression, user programmable
linearization curve as well as the measured value memory will be
deleted.
