P105 Empty Level
This parameter is to be set to the maximum distance from the face of the
transducer to the empty point, in P104 Measurement Units. Note this value
affects span as well, (see important information below), so should be set
before span.
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.
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.
