1. Zero Point Calibration
Open the detector in clean air, if there is readings after counting down.
Press the button "MENU" of the remote controller, the detector displays "F-01", press"+" or"-", change
the function to "F-04", and click "OK". The detector value will be displayed as 0.
In the zero calibration of oxygen detection transmitter, we must use nitrogen of purity over
99.99%.

2. Range Calibration
1. Enter into "F-07"as the same way above . The
"F-07" value is the concentration of the standard gas,
initialized to half of the measure range. This value can
be modified through the"+" and"-" keys to make it
consistent with the standard gas concentration which
need to be calibrated. Press
"OK" to exit.
2. Enter into"F-08"to change 0 into 1,then back to
detection interface.
3. Connect the 200-400mL/min standard gas in
detection interface, when the detector value is stable,
press "OK" for 3 seconds, then the instrument will be
calibrated automatically. The measured concentration
value is consistent with the value set in "F-07".
4. After calibration, left the detector in the air for a
while. Shut off the power when the detector value is
close to zero.
