Checkweighing
O
Over/Under Checkweighing
O
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.
Available Features
– Lower tolerance limit (minimum), target
value and upper limit (maximum) stored
in long-term memory
– Optional balance configuration in the
Setup menu for automatically initializing
this application 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
balance
– Enter target value and limits by placing
a load on the balance 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 key-
board input as target/tolerance value
stored corresponds to the display
accuracy
– Optional balance configuration in
the Setup menu for automatic output
to the interface port (print application
parameters) of target value and toler-
ance limits when initialization is
completed
– Control range for the balance’s data
output port lines is 30% to 170% of the
target value
– Control range can be set anywhere
from 10% to infinity. Control lines set
when stability is reached within the
control range; deleted only when you
exit this application
– Optional configuration in the Setup
menu for activation of control lines in-
dependent of weight value (weight
within control range, stability reached)
– Toggling the display between weight
readout and control (checkweighing)
display by pressing
v
. 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.”
– Toggle the text line display between
weight value and control display, nomi-
nal value “
setp
” and tolerance values
“
min
” and “
max
” by pressing the
w
key.
– Weight displayed on bar graph in rela-
tion to upper and lower limits and tar-
get value.
– Optional automatic printout of weight
when it is within the control range at
stability (
auto print +/-
).
After an automatic printout, the bal-
ance is blocked. Before you can gener-
ate the next printout, you must unblock
the balance by unloading it (weight
must be under 30% of the target) or by
placing a load on the balance (bringing
the weight up to at least 170% of the
target).
– Press
c
to delete the initialization
parameters and end the over/under
checkweighing program
