Purpose
Your balance comes equipped with an interface port for
connection to a computer or other peripheral device. You
can use a computer to change, start and/or monitor the
functions of the balance and the application programs.
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 ATL Models”, which you can download
from the Acculab website at www.acculab.com by selecting
“Download Instruction Manuals” from the “Service” menu.
The many and versatile properties of these balances can be
fully utilized for printing out records of the results when you
connect your balance to a Acculab data printer. The record-
ing capability for printouts makes it easy for you to work in
compliance with ISO/GLP.
