this is evaluated as a useful echo and output as the current level.
The reference plane for the measurement with radar sensors is
theloweredgeoftheangeorthesealingsurfaceofthethread.
The sensors are calibrated to this reference plane at the factory.
This parameter enables an adaptation of this factory setting, e.g. to

This value in " %" is additional safety below the 0 % adjustment

This parameter serves to activate/deaxctivate the HART signal in the
output.
This parameter serves to activate/deactivate the Safety Integrity Level
function.
9.5 Save parameter adjustment data
We recommended writing down the adjustment data, e.g. in this op-
erating instructions manual, and archiving them afterwards. They are
thus available for multiple use or service purposes.
If the instrument is equipped with a display and adjustment module,
the parameter adjustment data can be saved therein. The procedure
is described in menu item " Copy device settings".
