Clean air or high pure nitrogen
The RAEGuard 3 detector adopts a 2-point calibration method, i.e. zeroing
calibration and span calibration. The calibration of the detector should follow the
sequence below.
Note: The zero of the oxygen sensor does not need to be calibrated, nor does it
require bump test. Clean air in the environment (20.9% vol oxygen) can be used
to directly do span calibration.
