With the Weighing in Percent
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.
Features

100% using the keypad
– Save the current weight value as refer-
ence weight “pRef”
– Enter the reference percentage “pRef”
using the keypad
– Enter reference weight using a bar code

* Calculation is based on the active
net weight value and the percentage
entered.
To determine the weight of a sample
relative to a reference weight, you need
to define the reference weight value.
There are three ways to enter this value
in the application program:
– Calculation:
– Place the reference quantity (defined
by the reference percentage) on the
connected weighing platform and
press the
Start or p= soft key to
initialize the application.
– Place any amount of the sample
material on the connected weighing
platform, enter the reference per-
centage through the keypad, and
press the
pRef soft key to initial-
ize 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,
or saved with 10-fold or 100-fold reso-
lution, or with the maximum internal
resolution of the weighing platform.
– By entering the reference weight for
100% using the keypad and pressing
the
Wxx% soft key to initialize the
application.
– By using a bar code scanner
The initialization data remains valid
until deleted by pressing the c key
or until overwritten by a new value.
It also remains saved after you turn off
the Combics.
