4.6 AUTO BTU START UP AND VALVE TIMING
The Auto BTU Start Up process, which takes
about an hour to complete, automatically
performs the following sequence of tasks:
1. Sets the timing for each valve.
2. Matches all the component peaks.
3. Adjusts the timed events based on peak
integration times.
4. Runs a calibration.
5. Checks the range and order of response
factors.
6. Adjusts the retention time deviations to
avoid peak overlapping.
You can also initiate a valve timing run, which
is the first step of the Auto BTU Start Up
process, independently of that process. See
“Starting a Valve Timing Run” on page 12 for
more information.
4.6.1 Initiating an Auto BTU Start Up Run
To launch the Auto BTU Start Up process, do
the following:
1. If the GC is currently performing an
analysis, select Halt from the Control menu
to put the GC in Idle mode after the current
analysis run.
