The Calibrate CO

 Background screen is used to adjust the instrument 

zero, or background. Before making an adjustment, be sure the analyzer 
samples zero air for at least 5 minutes.

 

It is important to note the averaging time when calibrating. The longer the 
averaging time, the more accurate the calibration will be. To be most 
accurate, use the 300-second averaging time. For more information about 
calibration, see Chapter 4, “
