Span calibration
In span calibration mode, the detector will show a
detecting value in current situation, see as below picture.
At this time, cover the gas sensing hole of the detector by
using calibration cap, open the gas valve, adjust the gas flow to be
120mL/min, when the detector detect the gas available for
calibration within 30s, it will start the analysis program for
calibrating automatically, and the display value will slowly go up
to calibration concentration which you already set, a few seconds
after then, the calibration will be completed and screen go to next
