Temperature zone not ready
Temperature zone not ready
The GC has a number of heated zones in addition to the oven. These are inlets,
detectors and auxiliary, or "aux," zones. The GC is ready to start a run when
all the zones are within 1° C of the setpoint and have maintained the setpoint
temperature for 30 seconds. A zone that is turned off is considered ready.
If a temperature zone is unable to reach the setpoint, the GC will remain not
ready indefinitely. The instrument will not shut down unless a temperature
is out of the range for the zone.
