Zero Calibration
Zero calibration must be done in clean air. Zero calibration is needed when there is zero shift happens.
Put the detector in clean air for 3-5 minutes, under the detection interface, press the
“MINUS” buttons for three
seconds, the data of all channels will reset to zero automatically.
Note: Zero calibration of oxygen detector, nitrogen detector and carbon dioxide detector (target gases are
component of the air), the data will be defaults to 20.9%VOL (O2), 79.1%VOL (N2), and 400ppm (CO2). Do
not do the zero calibration in not clean air or when there is no zero shift happens.
