Over/Under Checkweighing H
Purpose
This program is used to check
whether a sample corresponds to
a pre-set target value or is within
a specific tolerance range. In
addition to the display in the
measured value line, the results are
shown on the bar graph and can
also be routed through the interface
port via control lines for further
electronic processing.
You can use this application program
in combination with a program
chosen from Application 1 (e.g.,
counting, weighing in percent) and
one from Application 3 (totalizing,
formulation, statistics).
Available Features
– Optional configuration in
the Setup menu for long-term
storage of target value and
tolerance limits
– Optional scale configuration
in Setup for automatically initializ-
ing this application and loading
the values stored in long term
memory for the target value
and the upper and lower toler-
ance limits when you turn on
the scale
– You can perform checkweighing
– without entering a target value,
but only upper and lower
tolerance limits;
– as differential checkweighing;
– with symmetric or asymmetric
limits which can be entered
as percentages
– Enter target value and limits by
placing a load on the scale or
using the numeric keys
– Control in entering target and
tolerance values, so that the upper
limit ≥ the target ≥ the lower limit
≥ 1 display increment
– Accuracy of a weight readout or
keyboard input as target/tolerance
values corresponds to the display
accuracy
– Optional scale configuration in the
Setup menu for automatic output to
the interface port (print application
parameters) of target value and
tolerance limits when initialization
is completed
– Control range for the scale’s data
output port lines is 30% to 170% of
the target value
– Optional configuration in the
Setup menu for activation of control
lines dependent on weight value
(weight value within control range,
stability reached)
– Toggling the display between
weight readout and control
(checkweighing) display by
pressing the corresponding soft
key. If the weight value exceeds
tolerances, the measured value
line shows the weight while the
control display shows “LL” for “too
low” or “HH” for “too high.”
– Press the Show soft key to
display target value and
tolerance limits in the text line
after initializing the application.
– Weight value in bar graph
displayed in relation to upper
and lower limits and target value.
– “OK” value counter displayed in
the text line (e.g., n = 4).
This counter shows the number
of measured values that lie within
the tolerance range.
– Optional automatic printout of
weight value when it is within the
control range at stability
After an automatic printout, the
scale is blocked. Before you can
generate the next printout,
you must unblock the scale by
unloading it (weight must be under
30% of the target) or by placing
a load on the scale (bringing the
weight up to at least 170%
of the target).
– Press c to delete the
initialization parameters and end
the Checkweighing program
