Igniting the phx42
1. Tap Ignite.
*During ignition attempts, filter detection is bypassed while the pumps come up to pressure. Failure
to ignite after three consecutive attempts should be reported to LDARtools. Continued attempts
to ignite the unit can result in contamination being pulled into the system.
The phx42 must be ignited for at least 15 minutes prior to calibration, drift,
as well as any monitoring that is going to be performed. If the analyzer is
used before it is warm, you may receive readings outside of the factory-
specified accuracy ranges.
