P106 Span
This parameter should be set to the maximum distance from the Empty
Level (P105) to the maximum material level. It is automatically set to be
equal to the Empty Level (P105) less the Near Blanking distance (P107),
when you set the empty level.
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, typically to ignore close in obstructions.
P101 = dBMach3 Transducer
Default Blanking Distance = 0.00 inches
Default Blanking Distance = 4.921 inches
Default Blanking Distance = 11.811 inches
Default Blanking Distance = 11.811 inches
Default Blanking Distance = 19.685 inches
Default Blanking Distance = 7.874 inches
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
10% 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.
Important Information
When using the dB 3 the maximum distance, that can be measured
inclusive of far end blanking is 118.116 inches.
