(3) Ensure that all of the Analyzer Valve Switches, upper enclosure, are set to the AUTO
position.
(4) Ensure that the carrier gas bottle valve is open.

bottle to adjust pressure.
Do not use the "Carrier Pressure Adjust" valve (on the Flow Panel of the Analyzer) to adjust
carrier gas line pressure. That valve is factory-set and should not be adjusted.

purged with carrier gas.

settings described in steps (1) through (5) are maintained. No other settings should
be made.
