Checkweighing
Application O
With the Checkweighing application,
you can check whether the sample on
the weighing platform matches a target
value or lies within a given tolerance
range�
Checkweighing also makes it easy to fill
sample materials to a specified target
weight�
Characteristics
– Enter the nominal or target weight (set
point) and the tolerance range delimiters
either using the keypad or by saving the
weight value of a load on the platform�
– Enter the tolerance limits as absolute
values (Target, Min and Max) or via the
target value as percentage deviation
with user-dened percent limits or
withrelative limits�
Congured in the menu under:
Appl 2:
check.wg: 4.5.
– The target value can be taken over
as a weighed value from a weighing
platform, and the upper and lower
tolerance limits are dened as a
percentage deviation from the target
value (setting code 4�5�2)� The deviation
percentage can be changed using the
r key: 0�1%, 0�2%, 0�5%, 1%, 1�5%,
2%, 3%, 5% or 10%�
– The target value, lower tolerance limit
(minimum) and upper tolerance limit
(maximum) can be applied as weighed
values from the weighing platform�
– Target value and tolerance limits
checked during input; values must
conform to: upper limit > target >
lowerlimit > 1 digit�
– Checkweighing range: either 30% to
170% of the target, or from 10% to
infinity�
– Results are shown on main display on
the bar graph, as well as sent to control
output ports for further processing�
– Toggle the main display between weight
and tolerances limits by pressing the
w key� If the weight in the readout is
outside the tolerance range, “LL” (too
low) or “HH” (too high) is displayed�
– Activate Info mode with the I key

– Automatic initialization when you
switch on the scale with most recently
saved application data� Congured in
Setup under:
appl
: a.start: 3.8.
– You can assign dierent functions to
the c key for deleting applications�
When you clear applications, you can
delete either the data stored for all
applications or just selected data stored
for the active application� Congured in
Setup under:
Appl
: sel.cf: 3.24.
(Sel� CF function key c in
applications)
– Tare function:
1) If you store a tare (weight value)
by pressing the ) key, you can later
enter a tare value manually� The tare
value you enter is added to the stored
tare value� Setting: menu code 3�25�1
(factory setting)
2) A tare value entered manually
overwrites a stored tare value
(weightvalue)�
If you enter a tare value manually,
atare value (weight value) stored later
overwrites the manually entered value�
Setting: menu code 3�25�2
Congured in Setup under:
Appl: tare. f: 3.25.
– Restore factory default settings�
Configured in Setup under:
Appl: def.app: 9.1.
Checkweighing entails comparing the
current weight value to a defined target
value� You can enter the value for this
target using the keypad, or by saving
the weight value indicated� You can
also define upper and lower tolerance
limits based on this target� You can do
this by:
– Entering absolute values using the
keypad or placing the desired amount
of weight on the platform and saving
the value, or
– by entering each value as a percentage of
thetarget weight
The initialization data remains valid until
deleted by pressing the c key or until
overwritten by a new value� They remain
saved after the scale is switched o�
