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".

a singular designation should be entered for exact identification of
individual measuring points.
