P107 Near Blanking Distance
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 Xducer
(P101) selected. It should not be set to less than this figure, but can be
increased, typical to ignore close in obstructions.
Transducer
Near Blanking Distance
P101 = 1 Xducer is a dB3
Default Blanking Distance = 0.12m
P101 = 2 Xducer is a dB6
Default Blanking Distance = 0.3m
P101 = 3 Xducer is a dB10
Default Blanking Distance = 0.3m
P101 = 4 Xducer is a dB15
Default Blanking Distance = 0.5m
P101 = 5 Xducer is a dB25
Default Blanking Distance = 0.6m
P101 = 6 Xducer is a dB40
Default Blanking Distance = 1.2m
P101 = 7 Xducer is a dBS6
Default Blanking Distance = 0.2m
P108 Far Blanking Distance
This is the distance (as a
percentage
of empty level
P105
) beyond the
empty point that the unit will be able to measure, and by
default
is pre-set to
plus
20%
of the
empty level
.
If the surface being monitored can extend beyond the
Empty
Level
(
P105
)
then the far blanking distance can be increased to a maximum of 100% of
empty level.
This parameter is always entered as a % of empty level.
