You can find "Extended adjustment" in the next sub-chapter.
Measurement loop name
In the first menu item you can assign a suitable measurement loop
name. You can enter a name with max. 19 characters.
Medium type
In the next menu item you can see which product type the instrument
is suitable for. If your instrument is only suitable for a certain medium,
this menu item is not visible.
Application
In this menu item, you can select the application. You can choose
between level measurement and interface measurement. You can
also choose between measurement in a vessel or in a bypass or
standpipe.
Medium - dielectric constant
In this menu item, you can define the medium type (product).
Max. adjustment
In this menu item, you can enter the max. adjustment for the level.
Enter the appropriate distance value in m (corresponding to the
percentage value) for the full vessel. The distance refers to the sensor
reference plane (seal surface of the process fitting). Keep in mind that
the max. level must lie below the dead band.
Min. adjustment
In this menu item, you can enter the min. adjustment for the level.
Enter the suitable distance value in m for the empty vessel (e.g.
distance from the flange to the probe end) corresponding to the per-
centage value. The distance refers tot he sensor reference plane (seal
surface of the process fitting).
Linearization
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.
