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.
Default Blanking Distance = 0.410 feet
Default Blanking Distance = 0.984 feet
P101 = 3 Xducer is a dB10
Default Blanking Distance = 0.984 feet
P101 = 4 Xducer is a dB15
Default Blanking Distance = 1.640 feet
P101 = 5 Xducer is a dB25
Default Blanking Distance = 1.969 feet
P101 = 6 Xducer is a dB40
Default Blanking Distance = 3.937 feet
P101 = 7 Xducer is a dBS6
Default Blanking Distance = 0.656 feet
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 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.
