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 the “Checkweighing” appli-
cation in combination with a program
chosen from Application 1 (e.g., count-
ing, 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 initializing this appli-
cation and loading the values stored in
long term memory for the target value
and the upper and lower tolerance
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

increment
– Accuracy of a weight readout or key-
board 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
