P*107 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
(
P*101
) selected. It should not be set to less than this figure, but
can be increased, typically to ignore close in obstructions.

P101 = dBR8
Default blanking distance = *0.252 feetq
*The signal emanates from the curved face of the radar, but for the purposes
of measurement it is taken from the drip shield.
P*108 Far Blanking Distance
This is the distance (as a percentage of the
empty level
(
P*105
) 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
(
P*105
) 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.
