Sartorius CH3E, Operating Instructions Manual

Page: 12 / 96

With Combics 3 you can
– collect weight values from two
weighing platforms
– use application programs to calculate
and display results
– assign codes to identify the samples
weighed
Before you begin, you need to configure
your Combics complete scale for your
requirements. This is achieved by
setting parameters in the operating
menu (for example, to configure a
connected printer). You can then begin
operation, with functions active for
storing and calculating weighing data.
The description of the operating design
is divided into the following sections:
– Data Input
– Display Modes
– Error Codes
– Data Output
– Saving Data
Data Input

keyboard

Whether a function is available at a

have a second function, activated by
pressing and holding the key for longer
than 2 seconds.
