The [Status] key

10
This manual provides lists of symptoms and corresponding
tasks to perform should you experience errors associated with
GC hardware or chromatographic output, GC Not Ready
messages, and other common issues.
Each section describes a problem and provides a bulleted list of
possible causes for you to troubleshoot. These lists are not
intended for use in the development of new methods. Proceed
with troubleshooting under the assumption that method(s) are
working properly.
This manual also includes common troubleshooting tasks as
well as information needed prior to calling Agilent for service.
While this manual describes troubleshooting for 7890 Series
GCs in general, when describing GC keyboard usage and
firmware features, this manual assumes a 7890B GC using
firmware B.02.01. Features that are specific to one GC model
only (7890A or 7890B) are noted.
Use the following steps as a general approach to
troubleshooting:
1
Observe the symptoms of the problem.
2
Look up the symptoms in this manual using the Table of
Contents or the Search tool. Review the list of possible causes
of the symptom.
3
Check each possible cause or perform a test that narrows the
list of possible causes until the symptom is resolved.
Be sure to also use the [Status] and [Info] keys on the GC keypad
while using this troubleshooting information. These keys will
display additional useful information related to the status of the
GC and its components.
