Checkweighing
O
When the Checkweighing application is
selected, you can check whether sample
weights correspond to a specified target
weight; i.e., whether the weight on the
weighing instrument is within a given
tolerance range. The tolerance range
is defined by upper and lower limits.
The result is displayed in the main
indicator, in the bar graph and by color-
coded LEDs.
Features:
– The target value can be taken over
as a weighed value from a weighing
instrument, and the tolerance limits
are defined as a perceptual deviation
from the target value. The following
percentages can be selected as the
deviation: 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 taken over
as weighed values from the weighing
instrument.
– Target 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
– Application started automatically
with most recent application data
when Combics switched on
– Automatic taring
– Automatic printing
– Toggle the display between weight
and tolerances limits by pressing
w
.
When tolerances are displayed, weights
exceeding the tolerance limits are
shown with “
LL
" (too low) or “
HH
"
(too high).
– Digital input/output interface
– Info mode for display of tolerance limits
by pressing
w
(> 2 sec)
Checkweighing entails comparing
the current weight value to a defined
target. The target value has a tolerance
range which can be entered either as
an absolute value or percentage (menu
item 4.5).
– Entering the tolerance range as
an absolute value (weighed value)
(menu item 4.5.1):
Start initialization by pressing
O
;
the middle segments of the bar graph
flash to prompt the placement of the
weight on the weighing instrument.
Place the weight on the instrument and
press
O
to store.
The bar graph segment for the lower
limit flashes to prompt the weight for
lower limit. Place the weight on
the weighing instrument and press
O
to store.
The bar graph segment for the upper
limit flashes to prompt the weight for
upper limit. Place the weight on the
weighing instrument and press
O
to
store.
– Entering the tolerance range as
a percentage (menu item 4.5.2):
A value for the percentage is shown in
the numeric display (lower right-hand
corner) together with the “%" sign.
Press
r
to change the percentage
value (0.1%, 0.2%, 0.5%, 1%, 1.5%, 2%,
3%, 5%, 10%).
Start initialization by pressing
O
;
the middle segments of the bar graph
flash to prompt the placement of the
weight on the weighing instrument.
Place the weight on the instrument and
press
O
to store. To can change the
percentage value for the tolerance limits
again before the target value is stored,
press
r
.
Before the new initialization, the
previous initialization values must be
deleted by pressing
c
.
– 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
default)
2) A tare value entered manually over-
writes 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
