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 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 overll 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.

With radar sensors with standpipe antenna, the sensor length is

already preset in this menu item. When shortening the standpipe

antenna afterwards, this value must be appropriately corrected.
