Weighing in Percent
L
(Combics 2)
With this application, you can use your weighing platform to obtain weight readouts
in percent which are in proportion to a reference weight.
L
is displayed as the
weight unit. Selection and settings in the
Applic. / Applic.1 / PERCENT
menu.
Features – Save the current weight value as reference weight “pRef”
– Enter the reference weight “Wxx%” for 100% using the keypad
– Enter the reference percentage “pRef” using the keypad
– Enter reference sample weight using a barcode scanner
– Display result as loss (difference) or residue
– Display up to 3 decimal places (menu item 3.10)
– Weighing in percent with two weighing platforms
– Activate Info mode via the
I
key
– Toggle between percent display and weight display using the
w
key.
– Automatic taring of container weight (
APPLIC./aut. / aut.tare
menu
item 3.7).
– Automatic initialization when the scale is switched on. The application is
initialized with the most recently saved data (
APPLIC. / aut.Strt
menu
item 3.8)
Exit application, delete parameters
The value of the reference sample weight in the reference memory remains active
until it is deleted via the
c
key or overwritten or until the application is changed.
The reference sample weight also remains saved after the scale is turned off.
You can assign different functions to the
c
key for deleting applications. When
you clear applications, you can delete either the data stored for all applications or
just selected data stored for the active application.
Setting:
Applic./CLER.CF

Tare function:
If you store a tare (weight value) by pressing the

key, you can later enter a tare
value manually. The tare value you enter is added to the stored tare value. Setting:
Applic. / TARE.FNC
menu item 3.25.1 (factory setting)
A tare value entered manually overwrites a stored tare value (weight value). If you
enter a tare value manually, a tare value (weight value) stored later overwrites the
manually entered value.
Setting:
Applic. / TARE.FNC
menu item 3.25.2
Restore factory default settings:
Applic./Reset
menu item 9.1.
To determine the weight of a sample relative to a reference weight, you need to
define the reference percentage value. There are different ways to enter this value in
the application:
Calculating the reference percentage value
-
Place the reference quantity (defined by the reference percentage value) on the
connected weighing platform and press the
O
key to initialize the application.
or
- Place any amount of the sample material on the connected weighing platform,
enter the reference percentage value through the keypad, and press the
r
key to
initialize the application.
How the reference weight is calculated depends on the application setting that
defines “Accuracy for saving weights”. The value is either rounded off in accordance
with the display resolution, saved with 10-fold or 100-fold resolution.
