P1-107, P2-107 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 = dBMach3 Transducer
Default Blanking Distance = 0.000 feet
P101 = dB3 Transducer
Default Blanking Distance = 0.410 feet
P101 = dB6 Transducer
Default Blanking Distance = 0.984 feet
P101 = dB10 Transducer
Default Blanking Distance = 0.984 feet
P101 = dB15 Transducer
Default Blanking Distance = 1.640 feet
P101 = dB25 Transducer
Default Blanking Distance = 1.969 feet
P101 = dB40 Transducer
Default Blanking Distance = 3.937 feet
P101 = dBS6 Transducer
Default Blanking Distance = 0.656 feet
P108 Far Blanking Distance
This is the distance (as a percentage of empty level P1-105, P2-105)
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
(P1-105, P2-105) 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.
