Keypad Functionality When the GC Is Controlled by an Agilent Data System
When an Agilent data system controls the GC, the data
system defines the setpoints and runs the samples. If
configured to lock the keypad, the data system can prevent
the changing of setpoints. The Remote LED is lit when a data
system is controlling the GC. Lit LEDs on the status board
show the current progress of a run.
When an Agilent data system controls the GC, the keypad
can be used:
• To view run status by selecting [Status]
• To view the method settings by selecting the GC
component key
• To display the last and next run times, the run time
remaining, and the post- run time remaining by repeatedly
selecting [Time]
• To abort a run by selecting [Stop]
• To find which computer is controlling the GC by pressing
[Options] > Communication, then scrolling. The name of the
computer controlling the GC is listed after the Enable DHCP
setting, along with the number of hosts connected to the
GC.
The Service Mode Key
[Service Mode] Is used to set up Early Maintenance
Feedback and to access inlet leak checks for
selected inlet types. See “Early Maintenance
Feedback (EMF)” on page 120 and the
Troubleshooting manual. This key also
accesses settings intended for service
personnel. Because these advanced settings
can cause problems if misused, avoid the
service settings unless specifically directed to
use them.
