66 Operating Instructions Combics CAIXS2
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
value by one step (display resolution x 10), “100-fold" increases it two steps
(display resolution x 100).
Setting:
Applic./Applic.1/PERCENT/RESOLUT
menu item 3.9.
Decimal places
The number of decimal places displayed can range from none up to 3 places.
Setting:
Applic./Applic.1/PERCENT/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/PERCENT/SAVE WT.
menu item 3.11.
Weighing in Percent with
You can use two weighing platforms simultaneously with the Weighing in Percent
two weighing platforms
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 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.
Weighing in Percent 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.
