5.0 Operation of Analyzer Trio
5.1 Turning on Analyzers:
1) Attach a 1.0 to 5.0 L/min flow of ambient air using the battery powered air pump or
sample flow from a compressor pumping only ambient air, or calibration gas with a 21%
O
2
mixture to the Analyzer Trio. This is necessary for the Pro O
2
Analyzer to calibrate
accurately at startup.
If no other method is available, use a short length of neoprene hose attached to the air
input to suck air backward across the sensors. This will draw fresh ambient air into the
enclosure. DO NOT blow into the tube as expelled breath contains lower oxygen content
and will cause improper calibration.
2) Turn on each analyzer by holding down the On/Off button until the display shows the
startup cycle.
3) Monitor for the low battery warning on battery powered units. Turn off the analyzers, plug
in the battery charger, and turn the analyzers back on if the battery warning appears.
4) Once fully cycled, the screens should display digits.
