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. 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 instruments with appropriate approval are used
as part of an overfill protection system according to WHG:
If a linearisation curve is selected, the measuring signal is no longer
necessarily linear to the filling height. This must be considered by the
user especially when setting the switching point on the limit signal
transmitter.
After a reset, certain parameter adjustments made by the user are
reset.
The following reset functions are available:
Delivery status:
Restores the parameter settings at the time of ship-
ment from the factory, incl. order-specific settings. Any stored false
signal suppression or user-programmed linearisation curve, as well
as the measured value memory, are deleted.
Basic settings:
Restores the parameter settings, incl. special
parameters, to the default values of the respective instrument. Any
stored false signal suppression or user-programmed linearisation
curve, as well as the measured value memory, are deleted.
Setup:
Restores the parameter settings made in the menu item
Setup to the default values of the respective instrument. False signal
suppression, user-programmed linearisation curve, measured value
memory and event memory remain untouched. The linearisation is set
to linear.
