Function description
Offset relating to a reference location
(distance). This value is positive when the
reference location is above the device flange
face and negative if below. For more data,

Offset relating to a reference location
(level). The device reference point for this
parameter is the bottom of the tank (set in
menu item C1.2 Tank Height). This value is
positive when the reference location is
below the tank bottom and negative if above.

This menu item is set by default to "Direct
Measuring" to measure the level of most
tank contents. The device uses the largest
radar signal to monitor level. If it is possible
there will be an interference signal in the
measurement zone that is larger than the
level signal, select "Direct Plus" mode. If
you select "Direct Plus" mode, the device
locks on the level signal and monitors
changes in level. If the device then finds
larger reflections in the silo, it will only
monitor the largest signal in a small search
zone around the first reflection found and
ignore all other reflections. The
interference signal must not be near to the
level signal. Refer also to "Measuring
principle" on page 116.
