Important Information
When changing the Empty Distance (P105) you can also recalculate the
values for the Span so that it equals the empty distance (P105) minus Near
Blanking (P107) and the Relay Setpoints, so that they remain at the same
percentage values of the empty distance as they were before you changed
the empty distance (P105). You will be asked the question “Recalculate
Span?” if you choose yes (enter 1), then the span will be recalculated. Any
other answer will leave the span at its original value. You will then be asked
if you want to “Recalculate Setpoints?”, if you choose yes (enter 1), then all
Relay Setpoints will be recalculated as a percentage of the new empty
distance. Any other answer will leave the setpoints at their original values.
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 sets 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.
Transducer Near Blanking Distance
P101 = dBMach3 Transducer Default Blanking Distance = 0.000m
P101 = dB3 Transducer Default Blanking Distance = 0.125m
P101 = dB6 Transducer Default Blanking Distance = 0.300m
P101 = dB10 Transducer Default Blanking Distance = 0.300m
P101 = dB15 Transducer Default Blanking Distance = 0.500m
P101 = dB25 Transducer Default Blanking Distance = 0.600m
P101 = dB40 Transducer Default Blanking Distance = 1.200m
P101 = dBS6 Transducer Default Blanking Distance = 0.200m
P101 = dB50 Transducer Default Blanking Distance = 2.000m
P101 = dBR16 Radar Default Blanking Distance = *0.077m
P101 = dBR8 Radar Default Blanking Distance = *0.077m
*The signal emanates from the curved face of the Radar, but for the purposes
of measurement it is taken from the drip shield.
