The Calibrate Zero screen is used to automatically adjust the O

background, or perform a “zero calibration”. Before performing a zero
calibration, ensure 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.
