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 linearization 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 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.
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
linearly proportional to the level. This must be taken into consideration
by the user, particularly when setting 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:
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.
