Dimensions
P104 Measurement Units
This parameter sets the units you want to use for programming and display
Option
Description
1 = metres All units of measure are METRES
2 = cm All units of measure are CENTIMETRES
3 = mm All units of measure are MILLIMETRES
4 = feet All units of measure are FEET
5 = inches (Default) All units of measure are INCHES
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 using the dB Mach 3 the empty distance is measured from
the end of the horn to the empty point in P104 Measurement
Units.
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.
