The keypad
All of the parameters required to operate the Agilent 7890A
GC can be entered through the GC’s keypad. Normally,
however, most of these parameters are controlled using an
attached data system, such as the Agilent ChemStation.
When the Agilent ChemStation is controlling your Agilent
7890A GC, it is possible for the ChemStation to disable
editing of the GC’s current method from the keypad.
