P107 Near Blanking
This parameter is the distance from the face of the transducer that is not
measurable and is pre-set to the minimum value dependant on the
Transducer (P101) selected. It should not be set to less than this figure, but
can be increased, typically to ignore close in obstructions.

*The signal emanates from the curved face of the radar, but for the purposes
of measurement it is taken from the drip shield.
P108 Far Blanking Distance
This is the distance (as a percentage of the empty level P105) beyond the
empty point that the unit will be able to measure, and by default is pre-set
to 20% of the empty level.
If the surface being monitored can be extended beyond the empty level
(P105) then the far blanking distance can be increased to a max. of 100% of
the empty level, provided it does not exceed the max range of the
transducer being used. This parameter is always entered as a % of the
empty level.
