Configuring Weighing Platforms
Analog/Digital Converter (ADC)
Purpose Adjust the parameters of the analog/digital converter to the connected load cell or
weighing platform. After ADC configuration, the ADC in connection with the load
sensor is defined as a scale.
Once the ADC configuration has been locked, the indicator can no longer be used
3
to influence weighing results. The scope of functions available in the weighing
instrument is defined by the A/D converter. Weighing functions that can be
activated include reading weight values, taring, adjustment, reading the tare
value and saving/deleting the tare entry.
Setup information – ADC configuration is only possible when the menu access switch is open. Close
the menu access switch after ADC configuration, as otherwise there will not be
any display of the conditions “overload" ( H ) and “underload" ( L ).
– Before ADC configuration, you must first set whether or not the weighing
platform will be used as a standard or verifiable weighing platform under menu
item 9.1.
– When the Service mode is activated, the ADC configuration takes place in the
Setup menu under WP-1 for the first weighing platform and under COm1 /
WP-2 for the second weighing platform.
If you return to the highest level of the Setup menu without saving the
3
configuration parameters beforehand (menu item 11.10) any settings that have
been made will be deleted.
– The settings are made in the corresponding Setup menu under menu item 11.
– Enter the maximum capacities in a suitable weight unit, without any decimal
places (decimal places will be truncated by the rounding function).
– Entries made in the ADC configuration will not be affected by a menu reset
(returning the setup parameters to their factory settings).

Setting Parameters for ADC Configuration
Standard or verifiable configuration In ADC configuration, you must first select whether the weighing platform should
be configured as a standard or verifiable (for use in legal metrology) weighing
platform.
– Standard configuration STANDRD (9.1.3)
– Verifiable configuration VERIF. (9.1.4)
Configuration unit 1.WT.UNIT Menu item 1.7
The weight unit used in the ADC configuration must have previously been selected
here.
Range selection RANGE Menu item 11.3
Depending on the setting under this menu item, the Menu items 11.5, 11.6 and
11.7 will either be displayed or will not be displayed for further configurations.
– Single-range scale (11.3.1)
The entire weighing capacity is divided into decimal numbers dependent on the
smallest scale interval d and the maximum weight. The readability corresponds
to the scale interval d.
– Multiple-range scale (11.3.2)
A multiple-range scale has two or three weighing ranges. When the range limit
for the lower weighing range is exceeded, the scale switches into the next
highest weighing range (lower resolution). The scale only switches back to the
lower weighing range (higher resolution) when the weighing platform has been
completely unloaded after pressing the key (.
– Multi-interval scale (11.3.3)
The function “Multi-interval scale" divides the weighing capacity into a
maximum of three ranges with differing readability. The corresponding change
takes place automatically at the defined range limits. Once the scale has been
tared, the highest possible resolution is available even if the weighing platform
is loaded.
Scale interval d Scale interval d indicates the resolution of the weighing instrument.
The scale interval can only be entered in increments of 1, 2, 5, 10, 20, etc.
When “Verifiable configuration” is used, this menu item is not displayed. When
using verifiable or verified weighing platforms (classes l and m), scale interval d is
the same as verification scale interval e.
Verification scale interval e Verification scale interval e indicates the resolution of the weighing instrument in
legal metrology.
The scale interval can only be entered in increments of 1, 2, 5, 10, 20, etc.
When “Standard configuration" is used, this menu item is not displayed.
Maximum load (max. load) The maximum load is the maximum amount of weight that may be placed on the
weighing platform. When heavier weights are used the weighing instrument
displays overload “H".
The scale intervals of the weighing instrument are calculated using the maximum
load and the scale interval d (e.g. max. capacity = 15.000 kg, smallest scale interval
d = 0.005 kg yields 3000 scale intervals).
In legal metrology the total number of intervals must be no more than 3000 e, and
when using multi-interval scales there must not be more than 3000 e intervals per
range.
In standard operation, as opposed to legal metrology, you can define a “Super
Range” weighing instrument of over 3000 intervals. These parameters, however,
may be influenced by physical restrictions.

Minimum load (min. load) When “Standard configuration” is used, this menu item is not displayed.
The minimum load of the connected weighing platform is entered under this menu
item. The minimum load for scales of class l is 20 e and 10 e for class m.
Attention: The function of the minimum load setting is to warn operators that
below this limit, the summation of tolerances might lead to significant measurement errors. In Germany, for example, initial weights below the minimum load are
not allowed.

– Printing weight value:
– GMP printout
– Automatic printout
– Automatic data output (see Data Interfaces chapter)
Automatic Taring (APPLIC menu item 3.7):
When the menu item is active (3.7.2), the first weight on the scale that exceeds the
preset minimum load is stored in the tare memory at stability.
The scale returns to the initial state when the load on the scale is less than 50% of
the minimum load.
Minimum load for automatic taring and automatic printing
(menu item 3.5):
You can set the following for the minimum load:
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 for the connected weighing platform.
If the interval is 1 g and 1000 digits are required, the minimum load is 1000 g
(1000 intervals).
If the weighing platform interval is 5 g and the same number of digits as above is
required, the minimum load is 5000 g.
36 Operating Instructions Combics CAIXS2
When the load exceeds the minimum load limit, the weighing platform is tared
automatically and/or a report printout is generated automatically; however, this
requires the corresponding menu items to be active for automatic taring (menu
item 3.7.2) and for automatic printing (menu 7.15.2).
Operation
Automatic printing (PROTOC menu item 7.15):
When the menu item (7.15.2) is active, the first weight value that exceeds the
minimum load is printed.
If the menu item is also activated for automatic taring, it is only tared when the
minimum load is exceeded. In this case, an automatic printout would only be
generated when the second weight value exceeds the minimum load.
Main scale: first platform displayed on start-up
You can select the weighing platform to be displayed first when CAIXS2 is turned
on in the Setup menu under “UTILIT" (menu item 8.11.).

SQmin Function
Purpose To display the allowable minimum sample quantity “SQmin" (sample quantity
minimum) in accordance with the United States Pharmacopoeia (USP). According
to USP guidelines, the uncertainty of measurement may not exceed 0.1% of the
sample quantity when substances are weighed with the highest degree of accuracy
for volume determination. This additional function ensures that weighing results lie
within defined tolerance limits corresponding to the requirements of your quality
assurance system.
Prerequisites The scale must be set up by a service technician to be able to use the SQmin
function. The technician will determine the permitted minimum sample quantity
and load this to your scale using the guidelines of your QA system. He or she will
document this setting via a “Weighing module test as per USP" certificate in which
the measurements and min. sample quantity are logged. The SQmin function
ensures that the weighing results correspond to USP guidelines. These SQmin
settings cannot be changed by the user.
Features – Displaying the minimum sample quality: After you press the k key, the value
is displayed in the text line for 4 seconds.
– If the minimum sample quantity has not been reached: The k symbol is
displayed and weight values are marked with a “!" in the printout.

Minimum load for initialization You can set the minimum load here, i.e., the load that must be placed on the
weighing platform in order to carry out the application. If the load on the platform
is too light, the following will occur:
– error code Inf 29 appears
– the weighing platform is not initialized
– the preset reference sample quantity is saved.
Setting: APPLIC./APPLIC.1/COUNT./MIN.INIT menu item 3.6.
The minimum load can be set in 10 steps, from 1 to 1000 digits (see Available
parameters). 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.
52 Operating Instructions Combics CAIXS2
Operation
Resolution The resolution indicates the accuracy used to determine the reference weight.
The default setting is “display resolution." The resolution is increased when
“10-fold" or “100-fold" is selected. “10-fold" increases the resolution of the net
value by one step (display resolution x 10), “100-fold" increases it two steps
(display resolution x 100).
Setting: APPLIC./APPLIC.1/COUNT./RESOLUT menu item 3.9.
Parameter for saving weight values The weight on the platform is saved as a reference value as soon as the platform
has stabilized. “Stability" is defined as the point at which the fluctuation of a
measured value lies within a defined tolerance. The narrower the tolerance,
the more stable the platform is at “stability".
The “increased stability" setting has a lower tolerance so that the average piece
weight saves is more accurate and the results more reproducible; however,
the measurement time can take longer.
Setting: APPLIC./APPLIC.1/COUNT./SAVE WT. menu item 3.11.
Reference sample updating You can define whether or not the reference sample weight is updated
automatically during weighing using this setting. The reference sample weight
isupdated automatically only when the following criteria are met:
1. “Automatic" must be set for reference sample updating in the menu.
2. The current piece count exceeds the original piece count by at least two.
3. The current piece count cannot be more than double the size of the original
piece count. This limitation does not apply to the first update if the piece
weight was entered via a keypad.
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 reference sample updating is selected in the menu and the piece count
(pcs) is displayed, the Auto symbol is displayed below the bar graph. If the reference
sample weight has been updated since you began weighing, the text line shows the
0ptsymbol. During an updating operation, 0pt and the updated piece count are
displayed briefly in the measured value line. The new reference sample weight and
reference sample quantity are saved.
Setting: APPLIC./APPLIC.1/COUNT./REF.UPDT menu item 3.12.
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.
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 one of the two scales as the reference scale.
The reference scale is the first scale active when you switch on the device,
regardless of the setting for automatic initialization of the Counting application.
Counting with One Reference Platform and One Weighing Platform
In this operating 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 sample weight with high
resolution; i.e., very precisely, and to count large amounts of parts, without
requiring an expensive high-resolution, high-capacity weighing platform.

Reference Weight
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 different ways to enter the
reference weight:
Calculating the Reference Weight
- Place the reference quantity (defined by the calculation factor) on the
connected weighing platform and calculate the reference sample weight by
pressing the O key.
or
- Place any amount of the sample material on the connected weighing platform,
enter the calculation factor through the keypad, and press the r key to
calculate the reference sample weight.
56 Operating Instructions Combics CAIXS2
Operation
How the reference weight is calculated depends on the application setting for
resolution. The resolution settings are either display resolution, display resolution
10-fold or display resolution 100-fold.
Entering the Reference Weight
The reference weight (e.g. the weight of one meter of electrical cable) can be

Operation
Minimum load for initialization You can set the minimum load here, i.e., the load that must be placed on the
weighing platform in order to carry out the application. If the load on the platform
is too light, the following will occur:
– error code Inf 29 appears
– the weighing platform is not initialized
– the preset reference sample quantity is saved.
Setting: Applic./Applic.1/neutr.m/Min.init menu item 3.6.
The minimum load can be set in 10 steps, from 1 to 1000 digits (see Available
parameters). 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.
Resolution The resolution indicates the accuracy used to determine the reference weight.
The default setting is “display resolution." The resolution is increased when
“10-fold" or “100-fold" is selected. “10-fold" increases the resolution of the net
value by one step (display resolution x 10), “100-fold" increases it two steps
(display resolution x 100).
Setting: Applic./Applic.1/neutr.m/RESOLUT menu item 3.9.
Decimal places 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 can range from none up to 3 places.
Setting: Applic./Applic.1/neutr.m/DEC.PLCS menu item 3.10.
Parameter for saving weight values The weight on the platform is saved as a reference value as soon as the platform
has stabilized. “Stability" is defined as the point at which the fluctuation of a
measured value lies within a defined tolerance. The narrower the tolerance,
the more stable the platform is at “stability".
The “increased stability" setting has a lower tolerance so that the average piece
weight saves is more accurate and the results more reproducible; however,
the measurement time can take longer.
Setting: Applic./Applic.1/neutr.m/SAVE WT. menu item 3.11.
Measuring with two weighing platforms You can use two weighing platforms simultaneously with the Neutral Measurement
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.
Neutral Measurement 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 one of the two scales as the reference scale.
The reference scale is the first scale active when you switch on the device,
regardless of the setting for automatic initialization of the Neutral Measurement
application.
58 Operating Instructions Combics CAIXS2
Neutral Measurement with One Reference Platform and One Weighing Platform
In this operating 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 piece 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, you can switch to the counting platform.
Example: 25 m of electrical cable is to be measured.
Configuration: The “Neutral Measurement" application is selected, and printout has
been set up (see “Configuration").

Minimum load for initialization You can set the minimum load here, i.e., the load that must be placed on the
weighing platform in order to carry out the application. If the load on the platform
is too light, the following will occur:
– error code Inf 29 appears
– the weighing platform is not initialized
– the preset reference sample quantity is saved.
Operating Instructions Combics CAIXS2 65
Operation
Setting: Applic./Applic.1/PERCENT/Min.init menu item 3.6.
The minimum load can be set in 10 steps, from 1 to 1000 digits (see Available
parameters). 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.
Resolution The resolution indicates the accuracy used to determine the reference weight.
The default setting is “display resolution." The resolution is increased when
“10-fold" or “100-fold" is selected. “10-fold" increases the resolution of the net

Parameter for saving weight values The weight on the platform is saved as a reference value as soon as the platform
has stabilized. “Stability" is defined as the point at which the fluctuation of a
measured value lies within a defined tolerance. The narrower the tolerance, the
more stable the platform is at “stability".
The “increased stability" setting has a lower tolerance so that the average piece
weight saves is more accurate and the results more reproducible; however, the
measurement time can take longer.

– 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 one of the two scales as the reference scale.
The reference scale is the first scale active when you switch on the device,
regardless of the setting for automatic initialization of the Neutral Measurement

Delimiters To use the Classification application, you need to enter the delimiters that separate
one class from another. Limits between the individual weigh classes are required for
the classification. 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:
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.
Operating Instructions Combics CAIXS2 77
Operation
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 values entered remain valid until deleted by pressing the c key or until
overwritten by a new value. They remain saved after the scale is switched off.

Minimum load The minimum amount that a component must weigh before it can be saved in net-
total memory.
Setting: APPLIC/ APPLIC.3/NET.TOT. Menu item 3.6.
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:
– error code Inf 29 appears
– a warning signal is emitted (double-beep)
– the weight value is not saved.
The minimum load required for automatic taring of the container weight on the
platform (first weight) is configured under: Applic. / min.tare menu item 3.5.
The minimum load can be set in 10 steps, from 1 to 1000 digits (see Available
parameters). The “digits" here refer to the scale intervals in the connected weighing
platform. If the interval of the connected platform is 1 g, and 1000 digits are
required, you must place at least 1000 g (= 1000 intervals) on the weighing
platform for autotaring (only with the “Autotare first weight" option selected).
Net-total formulation This mode is used for weighing large and small components at the same time. It is
with two weighing platforms possible to toggle from the small-component platform to the large-component
platform once during a measurement series. Once you toggle to the largecomponent platform, the ( and ) keys are available until a component is
saved. For example, you can tare a partially-filled container taken from the smallcomponent 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 largecomponent 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 large-component platform is an SBI instrument,
in which case the platform is only tared.

Configuring the Data Interface as a COM Port
(datprot)
You can configure the interface as a COM port in either COM1 or UniCOM,
“Data Protocol" (datprot) menu item.
SBI communication This is a simple ASCII interface.
Data output is configured under menu items 6.1 and 6.3:
– Manual output of displayed value with or without stability (menu items 6.1.1
and 6.1.2).
– Automatic output of displayed value with or without stability (menu items
6.1.4 and 6.1.5) at intervals defined by display updates. The number of display
intervals is set in menu item 6.3.
– Output of a configurable printout (menu item 6.1.7). Output is linked to the
“Printouts” menu item (datprot), (see page 96 “Configuring Printouts").
If you do not activate and configure a user-definable data record, the printout
simply contains the current value displayed on the display and control unit
(weight with unit, calculated value, alphanumeric display).
