• Once visual alignment is achieved on both the launch and detect and clean, dry purge gas
has been flowing, power may be applied to the analyzer.
• Begin the alignment process by starting at the launch end; maximize the signal (using the
transmission signal and value) by moving the launch around using the alignment bellows.
• Once maximum signal is achieved, move to the detect end and using the method described
in the previous slide, move the LAO/detect assembly around, until maximum signal is
achieved. (Note: CO detectors are more sensitive to miss-alignment than the O2 detector)
