GC in diagnostics mode
Status message: Diagnostics mode
The GC is not ready when it is in diagnostics mode. The instrument will be
in diagnostics mode whenever a Diagnostics control table has been accessed
through the
[Options] key.
You must exit the Diagnostics section for the GC to become ready.
Inlet purging
Status message: Front inlet purging or Back inlet purging
This condition applies only if you have a split/splitless inlet. The message
appears if you try to start a run while the inlet purge valve is still in the split
mode.
The inlet will remain not ready and continue purging until you press the Prep
Run key. Pressing Prep Run closes the valve (it also turns off the gas saver
mode and increases pressure for a pressure pulse, if selected).
Host system not ready
Status message: Host system
The GC will be in a Not Ready state if the integrator, ChemStation, or another
controlling device is not ready to begin a run.
External device not ready
Status message: External device
An instrument that is part of the start/stop bus is not ready. For example,
the automatic liquid sampler is not ready to begin injecting.
❐ The GC becomes ready when the other instruments on the bus are ready.
