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 plat-
forms 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 initializa-
tion of the Weighing in Percent appli-
cation.
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 capaci-
ty 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 initializa-
tion, the platform for larger amounts
is automatically activated.
The definition of one weighing plat-
form as a reference platform is config-
ured in Setup, under:
