18 Operating Guide
1 Introduction
The Operating Panel
The operating panel consists of the display, status lights, and
keypad. See “Keypad Operation” and the Advanced User
Guide, along with the complete suite of documentation
included on the Agilent GC and GC/MS Hardware User
Information & Utilities DVD that shipped with your
instrument for more detailed information.
The display
The display shows details of what is currently happening in
the Agilent 7890A GC and allows you to make changes to
parameters as necessary.
Use the scroll keys to view additional lines in the display.
A blinking asterisk (*) prompts you to press [Enter] to store
a value or [Clear] to abort the entry. You cannot perform any
other task until this is done.
Refer to “The keypad” and to “Keypad Operation” in this
document, or to the Advanced User Guide for more details
on how to interact with the displayed information.
