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 the following important information notices),
so should be set before span.
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.
Important Notice
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.
Important Notice
When using the dB Mach 3 the empty distance is measured from the end of the horn to
the empty point in P104 Measurement Units.
