Operating instructions

Minimum Load
The minimum load at initialization is
configured in the Application settings
(3.5: minimum load for automatic taring
and automatic printout; 3.6: minimum
load for automatic initialization).
You can choose from the following ten
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 weighing
platform 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.
If the interval of the connected platform
is 5 g, you have to place at least 5000 g
on the platform for initialization to
achieve the number of digits required
in the above example.
You can increase the resolution for
determining the reference weight by
changing the Application settings
for resolution (3.9) to use display
resolution + 1 decimal place, display
resolution + 2 decimal places, or
internal resolution. With the setting
for “Display resolution + 1 (2) decimal
place(s)", the resolution of the net value
is increased by one or two decimal
places; “Internal resolution" uses the
maximum resolution available in the
weighing platform.
Once the limit is exceeded by the load,
initialization can begin. If the load on
platform is too light for initialization,
the following will occur when you try
to initialize the application:
– The error inf 29 is displayed.
– A warning signal (double-beep)
is emitted
– The weighing platform is not initialized
– The preset reference sample quantity
is stored

Reference Sample Updating
In the Application settings under 3.12,
you can define whether the reference
sample is updated automatically.
Reference sample updating is performed
automatically only when the following
6 criteria are met:
1. Menu item 3.12.3 is selected in the
Application setup menu
2. The current piece count must exceed
the original piece count by at least two
3. The current piece count is less than
twice the original piece count (does not
apply to the first update if the piece
count is entered using a bar code
scanner).
4. The current piece count is less
than 100.
5. The internally calculated piece count
(such as 17.24 pcs) differs by less than
± 0.3 pcs from the whole number
(17 pcs in this example).
6. The weighing platform is stable in
accordance with the defined stability
parameter.
If automatic reference sample updating
is selected in the Application settings
and the piece count (pcs) is displayed,
the AUTO symbol is displayed in
addition to the Counting symbol (Z). If
the reference sample has been updated,
OPT is displayed continuously next to
the "AUTO" symbol. During a reference
sample updating operation, both 0pt
and the current reference sample
quantity are shown briefly in the main
display.
At the conclusion of reference sample
updating, a beep is sounded and the
new reference weight and reference
sample quantity are stored. You can
view these values when the weighing
platform is in Info mode.
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
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 the other. After starting a
counting routine on one platform, press
n to toggle to the other platform,
re-initialize the application and begin
a new counting operation.
You can define which of the two
platforms is active when the Combics
is switched on (8.11). This setting is
independent of 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
reference sample quantity with high
resolution; i.e., very precisely, and to
count large amounts of parts, without
requiring an expensive high-resolution,
high-capacity weighing platform.
The system toggles automatically to
the reference platform for initialization
(Ref is displayed). Following initializa-
tion, the system toggles to the counting
platform.
The system does not toggle auto-
matically for automatic reference
sample updating; the update is based
on whichever platform is active.
