Parameter for Saving Weight Values
The weight on the platform is saved
as a reference value when the platform
has stabilized. “Stability” is defined as
the point at which the fluctuation of
a measured value lies within a defined
tolerance range. The narrower the
tolerance range, the more stable the
platform is at “stability”.
In Setup, under:
Application:
Counting: Save wt.,
you can define whether the value is
saved when “standard stability” is
reached, or only at “increased stability”
(narrower tolerance range). If you
select increased stability, the value saved for average piece
weight will be more accurate and the
results more reproducible, but the
response time of the weighing platform
might be longer.
Accuracy of Average Piece Weight
Calculation
The resolution applied for calculating
the average piece weight is defined in
Setup under:
Application:
Counting: APW calcul.
The resolution for calculating the
average piece weight is increased if
“+1 decimal place”, “+2 decimal places”
or “Internal resolution” is selected.
With the “+1 decimal place” setting,
the net value is determined to one
additional decimal place (i.e., display
accuracy x 10); “+2 decimal places”
increases display accuracy + 100, and
so on up to the maximum resolution
available.
Minimum Load
The minimum load required for initialization of the weighing platform is configured in Setup under:
Application:
Counting: MinL.Init
Once the limit is exceeded by the load,
initialization can begin. If the load on
platform is too light, the following will
occur when you try to save the reference value:
– The error code inf 29 is displayed
– A warning signal is emitted (doublebeep)
– The weighing platform is not initialized
– The preset reference sample quantity is
saved
The minimum load required for automatic taring of the container weight on
the platform (first weight) is configured
in Setup under:
Application:
Counting:
MinL.Autotar
You can choose from the following
10 levels for this setting:
1 digit (no minimum load)
2 digits
5 digits
10 digits
20 digits
50 digits
100 digits
200 digits
500 digits
1000 digits
The “digits” here refer to the scale
intervals in the connected weighing
platform. If the interval of the connected platform is 1 g, for example,
and 1000 digits are required, you must
place at least 1000 g (=1000 intervals
=1000 digits) on the weighing platform
for initialization.
Average Piece Weight Updating
In Setup, under:
Application:
Counting: APW update
you can define whether or not the average piece weight is updated automatically during weighing. The average
piece weight is updated automatically
only when the following 6 criteria are
met:
1. The Automatic setting is selected
for average piece weight updating in
the Setup menu
2. The current piece count exceeds the
original piece count by at least two
3. The current piece count is less than
twice the original piece count (does not
apply for the first updating operation
if the piece count is entered using the
keypad or a bar code scanner)

Counting with Two Platforms of the
Same Type
Use this mode to count different types
of sample material with different
weights. For example, count the
lighter-weight pieces on one platform
and the heavier pieces on another.
You can define which of the two platforms is active when the Combics is
switched on. This is defined in Setup,
under:
Device: Operat.: Main

Counting with Two Weighing
Platforms
You can use two weighing platforms
simultaneously with the Counting
application. When using two platforms,
you can choose from the following
operating modes:
– Counting with two platforms of the
same type
– Counting with one reference platform
and one weighing platform
Pieces on
platform
4. The current piece count is less than
1000
5. The internally calculated piece count
(such as 17.24 pcs) differs by less than
± 0.3 pcs from the nearest whole number (in this example: 17).
6. The weighing platform is stable in
accordance with the parameter defined
for saving weights.
If automatic average piece weight
updating is selected in Setup and the
piece count (pcs) is displayed, the
Auto symbol is displayed below
the bar graph. If the average piece
weight has been updated since you
began weighing, the text line shows the
“optimized” code: (opt.). During
an updating operation, 0pt and the
updated piece count are displayed
briefly in the measured value line.
An acoustic signal indicates the completion of reference updating. The new
average piece weight and reference
sample quantity are saved.
This is the first platform active when
you switch on the Combics, regardless
of the setting for automatic initialization of the Counting application.
Counting with One Reference Platform
and One Weighing Platform
In this mode, the reference platform
is a high resolution weighing platform
with a relatively low maximum capacity.
The other platform is used for counting
large amounts, and has a high capacity
with a relatively low resolution.
This allows you to both determine the
average piece weight with high resolution; i.e., very precisely, and to count
large amounts of parts, without requiring an expensive high-resolution, highcapacity weighing platform.
The system can be configured to switch
automatically to the reference platform
for initialization (the measured value
line shows Ref). Following initialization, you can switch to the counting
platform.
The definition of one weighing platform as a reference platform is configured in Setup, under:
Application:
Counting:
Ref.wt.scale
If automatic average piece weight
updating is enabled, the update is performed on the active platform; in other
words, the system does not automatically switch to the reference platform.

* The calculation is based on the active
net weight value and the factor entered.
In order to calculate the length, surface
or volume of a given sample, the average weight of a reference quantity of
the sample must be known (in the
example below, the reference is 1 meter
of electrical cable). There are three
ways to enter the reference weight in
the program:
– Calculation:
– Place the reference quantity (defined
by the calculation factor) on the
connected weighing platform and
calculate the reference weight by
pressing the Start or n= soft
key.
– Place any amount of the sample
material on the connected weighing
platform, enter the calculation factor
through the keypad, and press the
nRef soft key to calculate the
reference weight.
How the reference weight is calculated
depends on the application setting for
resolution. The value is either rounded
off in accordance with the display
resolution, or saved with 10-fold or
100-fold resolution, or with the maximum internal resolution of the weighing platform.
– Keypad input: Enter the reference
weight (i.e., the weight of one meter
of electrical cable) using the keypad and
press wRef to save it.
– By using a bar code scanner
The initial application values are valid
until deleted by pressing the c key
or until overwritten by a new value.
They also remain saved after you turn
off the Combics.

Parameter for Saving Weight Values
The reference weight is saved when
the platform has stabilized. “Stability”
is defined as the point at which fluctuation of a measured value lies within a
defined tolerance range. The narrower
the tolerance range, the more stable the
platform is at “stability”.
In Setup, under:
Application:
Neut.Meas.: Save wt.,
you can define whether the value is
saved when “standard stability” is
reached, or only at “increased stability”
(narrower tolerance range). If you select
increased stability,
the reference weight saved will be more
accurate and the results more reproducible, but the response time of the
weighing platform might be longer.
Accuracy of Reference Weight
Calculation
The resolution applied for calculating
the reference weight is defined in Setup
under:
Application:
Neut.Meas.: Ref.calc.
The resolution for calculating the reference weight is increased if “+1 decimal
place”, “+2 decimal places” or “Internal
resolution” is selected. With the “+1
decimal place” setting, the net value
is determined to one additional decimal
place (i.e., display accuracy + 10);
“+2 decimal places” increases display
accuracy + 100, and so on up to the
maximum resolution available.
Decimal Places in Displayed Result
In neutral measurement, not only whole
numbers but also decimal numbers (for
example, 1.25 o electrical cabling) can
be displayed. The number of decimal
places displayed in neutral measurement is configured in Setup under:

Averaging (Animal Weighing) V
With the Averaging application, you
can use your weighing platform for
calculating weights as the average of a
number of individual weighing operations. These individual operations are
also known as “subweighing operations.”
This function is used to determine
weights under unstable ambient conditions or for weighing unstable samples
(such as live animals).
Features

Minimum Load
The minimum load required for initialization of the averaging routine is configured in Setup under:
Application: Animal
wgh: MinL.Start
Setting a minimum load for averaging
can be especially useful if you configure
automatic start of measurement.
The minimum load required for automatic taring of the container weight on
the platform (first weight), or for automatic printout of results, is configured
in Setup under:
Application: Animal
wgh: MinL.Autotar
You can choose from the following
10 levels for this setting:
1 digit (no minimum load)
2 digits
5 digits
10 digits
20 digits
50 digits
100 digits
200 digits
500 digits
1000 digits
The “digits” here refer to the scale
intervals in the connected weighing
platform. If the interval of the connected platform is 1 g, for example, and
1000 digits are required, you must
place at least 1000 g (=1000 intervals
=1000 digits) on the weighing platform
to start the averaging routine.
Starting the Measurements
The averaging routine does not begin
until the fluctuation in weight value
remains below a defined threshold
over three consecutive measurements.
The tolerance limit is defined as a percentage of the animal or object weight
(for example, 0.1%; 0.2%, 0.5%, etc., up
to 20%, 50%; 100%), configured in
Setup under:
Application: Animal
wgh: Averaging
If the “Averaging” parameter is set
to 2%, for example, and the animal or
object weighs 10 kg, measurement does
not begin until the fluctuation in
weight value remains below 200 g during three consecutive measurements.

Checkweighing 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.

Checkweighing entails comparing
the current weight value to a defined
target. 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 initial application values are valid
until deleted by pressing the c key
or until overwritten by a new value.
They also remain saved after you turn

1000 digits are required, you must
place at least 1000 g (=1000 intervals
=1000 digits) on the weighing platform
to activate autotaring or autoprint.
Display:
The result of a measurement is shown
either as a weight value or in relation to
the target.
– Weight display
The measured value line always shows
the weight value, even if it lies outside
the tolerance range.
The bar graph is displayed with symbols
indicating lower limit, target and upper
limit. Weights are shown logarithmically up to the lower tolerance limit, and
linearly beyond that point.
The LEDs are activated as follows:
Yellow: weight value > upper tolerance
limit
Green: weight value is within OK range
Red: weight value < lower tolerance
limit
If no LED is lit:
– the application is not completely
initialized, or
– the weight value is outside the
checkweighing range. (The limits
of the checkweighing range are
configured in Setup under:
Application:
Checkwgh.:

To use the Classification application,
you need to enter the delimiters that
separate one class from another.
Save the current weight value
as the upper limit of a weight
class
The lower limit of Class 1 is defined by
the preset minimum load. The other
classes are configured by defining their
upper limits. There are two ways to
enter the delimiters for classes 1
through 3 (or 5):
– By saving the weight value indicated:
Each upper limit value, with the exception of the highest class, is entered
using the keypad or by saving the
weight value of a load on the weighing
platform.
– By entering a percentage:
The upper value of Class 1 is entered
using the keypad or by saving the value
indicated. Upper limits for the other
classes are defined by entering a percentage of deviation from the upper
limit of Class 1, using the keypad.
Example: Enter 100 g as the upper
limit of Class 1. Then enter 15%.
When working with 3 classes, this yields
the following weight classes:
Class 0: up to the minimum load
Class 1: > minimum load - 100 g
Class 2: > 100 g – 115 g
Class 3: > 115 g - maximum load
When working with 5 classes, this yields
the following weight classes:
Class 0: up to the minimum load
Class 1: > minimum load - 100 g
Class 2: > 100 g – 115 g
Class 3: > 115 g – 130 g
Class 4: > 130 g – 145 g
Class 5: > 145 g - maximum load
The initial application values are valid
until deleted by pressing the c key
or until overwritten by a new value.
They also remain saved after you turn

* Calculation is based on the active
net weight value and the percentage
entered.
To determine the weight of a sample
relative to a reference weight, you need
to define the reference weight value.
There are three ways to enter this value
in the application program:
– Calculation:
– Place the reference quantity (defined
by the reference percentage) on the
connected weighing platform and
press the Start or p= soft key to
initialize the application.
– Place any amount of the sample
material on the connected weighing
platform, enter the reference percentage through the keypad, and
press the pRef soft key to initialize the application.
How the reference weight is calculated
depends on the application setting that
defines “Accuracy for saving weights”.
The value is either rounded off in
accordance with the display resolution,
or saved with 10-fold or 100-fold resolution, or with the maximum internal
resolution of the weighing platform.
– By entering the reference weight for
100% using the keypad and pressing
the Wxx% soft key to initialize the
application.
– By using a bar code scanner
The initialization data remains valid
until deleted by pressing the c key
or until overwritten by a new value.
It also remains saved after you turn off

Parameter for Saving Weight Values
The reference weight is saved when
the platform has stabilized. “Stability”
is defined as the point at which fluctuation of a measured value lies within a
defined tolerance range. The narrower
the tolerance range, the more stable the
platform is at “stability”.
In Setup, under:
Application: Wgh in
Pct: Save weight
you can define whether the value
is saved when “standard stability” is
reached, or only at “increased stability”
(narrower tolerance range). If you select
increased stability,
the reference weight saved will be more
accurate and the results more reproducible, but the response time of the
weighing platform might be longer.
Accuracy of Reference Weight
Calculation
The resolution applied for calculating
the reference weight is defined in Setup
under:
Application: Wgh in
Pct: Acc.save wts.
The resolution for calculating the reference weight is increased if “+1 decimal
place”, “+2 decimal places” or “Internal
resolution” is selected. With the “+1
decimal place” setting, the net value
is determined to one additional decimal
place (i.e., display accuracy x 10);
“+2 decimal places” increases display
accuracy x 100, and so on up to the
maximum resolution available.
Display
With the Weighing in Percent application, the result can be displayed as a
remainder or loss. Configured in Setup
under:
Application: Wgh in
Pct: Display
Equations:
Residue = Current weight /
100% weight + 100
Loss =
(current weight – 100%
weight) /
100% weight + 100
Minimum Load
The minimum load required for
initialization of the weighing platform
is configured in Setup under:
Application:
Wgh in Pct:
MinL.Init
Once the limit is exceeded by the load,
initialization can begin. If the load on
platform is too light, the following will
occur when you try to save the reference value:
– The error code inf 29 is displayed
– A warning signal is emitted (doublebeep)
– The weighing platform is not initialized
– The preset reference percentage is saved
The minimum load required for automatic taring of the container weight on
the platform (first weight) is configured
in Setup under:
Application: Wgh in

2 digits
5 digits
10 digits
20 digits
50 digits
100 digits
200 digits
500 digits
1000 digits
The “digits” here refer to the scale
intervals in the connected weighing
platform. If the interval of the connected platform is 1 g, for example,
and 1000 digits are required, you must
place at least 1000 g (=1000 intervals
=1000 digits) on the weighing platform
for initialization.
Weighing in Percent with Two
Weighing Platforms
You can use two weighing platforms
simultaneously with the Weighing in
Percent application. When using two
platforms, you can choose from the
following operating modes:
– Weighing in Percent with two platforms
of the same type
– Weighing in Percent with one reference
platform and one weighing platform
Weighing in Percent with Two
Platforms of the Same Type
Use this mode to measure different
types of sample material with different
weights. For example, measure the
lighter-weight samples on one platform
and the heavier samples on another.
You can define which of the two platforms is active when the Combics is
switched on. This is configured in
Setup, under:
Device: Operat.: Main
scale
This is the first platform active when
you switch on the Combics, regardless
of the setting for automatic initialization of the Weighing in Percent application.
Weighing in Percent with One
Reference Platform and One Weighing
Platform
In this mode, the reference platform
is a high-resolution weighing platform
with a relatively low maximum capacity.
The other platform is used for weighing
heavier samples, and has a high capacity with a relatively low resolution.
This allows you to both determine the
reference weight with high resolution;
i.e., very precisely, and to measure large
samples, without requiring an expensive
high-resolution, high-capacity weighing
platform.
The system can be configured to switch
automatically to the reference platform
for initialization (the measured value
line shows Ref). Following initialization, the platform for larger amounts
is automatically activated.
The definition of one weighing platform as a reference platform is configured in Setup, under:
Application: Wgh in

Once the limit is exceeded by the load,
the value can be saved. If the load on
platform is too light, the following will
occur when you try to save a value:
– The error code inf 29 is displayed
– A warning signal is emitted (doublebeep)
- The weighing platform is not initialized

Net-total Formulation with
Two Weighing Platforms
This mode is used for weighing large
and small components at the same
time.
This makes it possible to toggle from
the small-component platform to the
large-component platform during
measurement. Once you toggle to the
large-component platform, the ( and
) keys are available until a component is value is saved. For example,
you can tare a partially-filled container
taken from the small-component platform on the large component platform.
The value in component memory on
the small-component platform is transferred to the large-component platform
and the weight unit is converted,
if necessary. The Component and
Additive display modes are both available on the large-component platform.
The value read by the active platform
is saved in component memory. The
displayed result is accurately calculated
in the active weight unit.
When you press c to stop a measurement series the tare memories for both
platforms are cleared, unless the largecomponent platform is an SBI instrument, in which case the platform is only
tared.
The “digits” here refer to the scale
intervals in the connected weighing
platform. If the interval of the connected platform is 1 g, for example,
and 1000 digits are required, you must
place at least 1000 g (=1000 intervals
=1000 digits) on the weighing platform
for initialization.

Totalizing s
With the Totalizing application, you
can add weight values to the totalizing
memory. In addition to weight values,
the number of separate values added
to memory is also saved (transaction
counter).
Features
– Weigh in up to 999 items
– Current transaction number displayed in
the text line (indicating the items
already added)
– Weighing in up to a defined target,
with the totalization memory content +
current weight displayed in the text
line.
– Save weight values manually or automatically
– Accurate calculation of total of weight
values from two weighing platforms
– Activate info-mode by pressing D
(> 2 sec)
– Incomplete totalizing routines saved in
battery-backed memory. Configured in
Setup under:

Soft Key Functions
M+ Add net weight value from active
platform to totalizing memory.
The Combics has a totalizing memory
for adding individual net and gross
values. You can save weight values in
totalizing memory manually or automatically. Configured in Setup under:
Application:
Totalizing: Autosave
– Save value manually by pressing M+.
The value taken from the active
platform is added to the value already
saved in totalization memory and
the transaction counter value
is increased by one.
When a value is added manually,
the program does not check whether
the platform has been unloaded since
the last time the M+ soft key was
pressed.
– Value saved automatically when the
weighing platform is stable and the
defined minimum load is exceeded.
If the defined minimum load is not
exceeded, you can save the item
manually by pressing the M+ soft key.
Regardless of these settings, the current
value cannot be saved automatically
unless the platform is unloaded before
the next sample is placed on it.
The weighing platform is considered to
be unloaded when the load is less than
50% of the minimum load.
The number of items added to memory
is displayed in the text line.
Press the c key to clear the totalizing
memory. A printout is automatically
generated.
With 2 weighing platforms connected,
you can add values from both platforms
to the totalizing memory.
The displayed result is accurately
calculated in the active weight unit.
Example: When you add 1.243 kg
(determined on a weighing platform
with three decimal places) to 1.4 kg
(determined on a platform with
1 decimal place), the display shows
2.643 kg.
