Operating the Scale
Preparation
The checkweighing program requires
a target value for comparison
to the current value. This target has
a tolerance range, which is defined
by absolute weight values: upper
and lower limits. These limits can
be entered either by storing weights
on the scale or via key input.
There are four control lines,
called data output port lines, which
are activated as follows: (see also
the diagram at the right):
lighter
equal
heavier
set
The control range spans 30% to
170% of the target value. You can
configure this parameter in the
Setup menu (4 3 +/- ctrl ports on)
to select whether the control
lines are:
always on
activated within the control range
activated at stability
activated at stability within the
control range
This makes it possible,
for example, to connect a simple
indicator for the weighing results
(e.g., three different colors, one each
for the weighing results: too light,
O.K., too heavy).
