Checkweighing - Sartorius FB Operating Instructions Manual

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 scale configuration
in the Setup menu for automati-
cally 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 scale
– 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 value stored
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
– 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 independent
of weight value (weight within
control range, stability reached)
– Toggling the display between
weight readout and control
(checkweighing) display
by pressing v/[FUNCTION].
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, nominal value
"SetP" and tolerance values
"min" and "max" by pressing
the w/[TOGGLE] key.
– Weight displayed on bar graph in
relation to upper and lower limits
and target value.
– Optional automatic printout of
weight when it is within the
control range at stability (auto
print +/-).
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 over/under checkweighing
program
