The menu item "Delete" is used to completely delete an already cre-
ated 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 de-
tected. 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 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".
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 ship-
ment 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 lineari-
zation curve as well as the measured value memory will be deleted.
Setup: Resetting of the parameter settings to the default values of the
respective instrument in the menu item Setup. User-generated false
