Instrument Troubleshooting

The control unit of the GC performs a number of test routines to monitor and
report on the status of the major chromatographic and control functions.
Instrument malfunctioning, due to a component failure or to abnormal operating
condition is identified by the red lighting of the Not Ready/Error LED located on
the GC Status Panel.
When lit, this LED indicates that the injector and oven power has been cut off for
safety reasons and an error message indicating the possible cause of error appears
