changed. The reference sample weight also remains saved after the scale is turned
off.
You can assign different functions to the
c
key to delete applications. When you
clear applications, you can delete either the data stored for all applications or just
selected data stored for the active application.

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.
