Operating the Combics 2
Minimum Load
The minimum load at initialization is
configured in the Application settings
(3.5: minimum load for automatic taring
and automatic printing; 3.6: minimum
load for initialzation). 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 percentage is
stored
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 with two platforms of the
same type
– Weighing with one reference platform
and one weighing platform
Weighing in Percent with Two Platforms
Use this mode to weigh different types
of sample material with different
weights. For example, weigh the lighter-
weight samples on one platform and
the heavier samples on the other.
After starting a weighing routine on
one platform, press n to toggle to
the other platform, re-initialize the
application and begin a new weighing
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 initializiation
of the Counting 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
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 weigh large amounts of parts,
without requiring an expensive high-
resolution, high-capacity weighing
platform.
The system toggles automatically to
the reference platform for initializiation
(REF is displayed). Following initializa-
tion, the system toggles to the higher-
capacity platform.
