Check for any available firmware updates. Go to the Agilent
web site at
http://www.chem.agilent.com/_layouts/agilent/downloadFir
mware.aspx?whid=50307.
• If the available firmware version is newer than the version
on the GC, download it.
• If not, skip to the next section.
4 Verify that if a new firmware version is available, it is
compatible with the current hardware and software. For
example, verify that any data system is compatible with the
new firmware. If the new firmware is not compatible or
acceptable for any reason, skip to “PIDs” below.
5 If available, install any available firmware updates.
PIDs
You may need to update or change the PIDs for any AUX EPC or
PCM module installed in the GC:
• If the system includes an AUX EPC module for a CFT device
(Dean's switch, purged splitter, or so on) or headspace
application, use the Firmware Update Utility or Instrument
Utilities to update the AUX module PID constants according
to the application instructions. (Required)
• If the system includes a PCM module for controlling the
backpressure to a headspace sampling loop, use the
Firmware Update Utility or Instrument Utilities to update
the PCM module PID constants according to the application
instructions. (Required)
