VEGA VEGAPULS 61 (≥ 2.0.0 - ≥ 4.0.0) Profibus PA Approval according to LPR radio standard - Manual (Page 47)

Note:
Check the distance to the product surface, because if an incorrect (too
large) value is entered, the existing level will be saved as false signal.
The filling level would then no longer be detectable in this area.
If a false signal suppression is already created in the sensor, then the
following menu window appears when selecting "False signal
suppression":
The menu item "Delete" is used to completely delete an already
created false signal suppression. This is useful if the saved false signal
suppression no longer matches the metrological conditions in the
vessel.
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
"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.
