For the full vessel, enter the distance value in m matching the per-
centage value.
This menu item is only available if you have selected interface meas-
urement under the menu item "Application". If you have selected "Yes"
in the previous menu item (accept adjustment of the level measure-
ment), the current setting will be displayed.
If you have selected "No", you can enter the adjustment for the inter-
face measurement separately.
Enter the respective distance value in m for the empty vessel cor-
responding to the percentage value.
To damp process-dependent measured value fluctuations, set an
integration time of 0 … 999 s in this menu item.
If you have selected interface measurement under the menu item
"Application", you can adjust the damping for the level and the inter-
face separately.
The default setting is a damping of 0 s.
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, when 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.
The linearization applies to the measured value indication and the
current output. By activating the appropriate curve, the volume per-
centage 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".
