Preparation
You can set these parameters for other
devices in the Setup menu (see the chapter
entitled “Configuring the Balance”).
You will also find a detailed description
of the available data interface commands
in the file “Data Interface Descriptions for
AZ, GD, GE and TE Models”, which you can
download from the Sartorius website
(www.sartorius.com “Download Center”).
The many and versatile properties of these
balances can be fully utilized for printing
out records of the results when you con-
nect your balance to a Sartorius data print-
er. The recording capability for printouts
makes it easy for you to work
in compliance with ISO/GLP.
