NOTE

• As this system uses ambient air for the reference gas, measuring accuracy will be affected

by the installation location.

• A needle (stop) valve should be connected to the calibration gas inlet of the detector.

The valve should be fully closed unless calibration is in progress.

1.1.2 System 2

This system is for monitoring and controlling oxygen concentration in the combustion gases of a

large-size boiler or heating furnace. Clean (dry) air (21 vol% O

) is used as the reference gas and

the span gas for calibration. Zero gas is fed in from a cylinder during calibration. The gas ow is

controlled by the ZA8F ow setting unit (for manual valve operation).
