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

CENTIMETRES
3 = mm
All units of measure are
MILLIMETRES
4 = feet (Default)

FEET
5 = inches
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 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.
