"Direct" mode
The device uses the largest radar signal to monitor level.

"Direct Plus" mode
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.
CAUTION!
"DIRECT PLUS" MODES
It is important to enter the correct dielectric constant value in menu item C2.2 Epsilon R
Product. If this value is incorrect, the device will not measure level accurately.
