Calibrate Oxygen Analyzers as follows:
1) Turn off LP compressor and return LP Feed Air BP Regulator to minimum pressure setting by
turning adjustment knob CCW until it spins freely.
2) Slightly open fill whip valve on HP
Compressor to relieve any
residual pressure, and then, if
desired, insert clean rag in yoke
to act as sound muffler.
3) Adjust fill whip valve so the running HP Compressor maintains 1500-2000 psi (100-140 bar)
outlet
pressure. Air will now be flowing past both Oxygen Analyzers for calibration purposes.
4) Monitor all gauges for proper operating range and check all connections for leaks.
5) Calibrate Oxygen Analyzers while the HP Compressor is pumping air. Refer to the Oxygen
Analyzer manual included with the Nitrox System for details. Note that special calibration
procedures may be required when operating at altitudes above sea level.
