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. Default IMP 3 = 2.80m (9.19 feet), IMP 6 =
5.70m (18.70 feet) and IMP 10 = 9.70m (31.82).
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 version
of IMP+ i.s. being used. It should not be set to less than this figure, but can be
increased.
IMP+ i.s Version
Near Blanking Distance
IMP 3 metre
Default Blanking Distance = 0.2m (0.66 feet)
IMP 6 metre
Default Blanking Distance = 0.3m (0.98 feet)
IMP 10 metre
Default Blanking Distance = 0.3m (0.98 feet)
P108 Far Blanking Distance
This is the distance (as a percentage of empty level) beyond the empty
point that the unit will be able to measure, and the 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.
