2) Span calibration
a. Select the gas that needs to be calibrated; take CH4 as example
b. Inlet calibration gas and check the real-time concentration. (e.g. if CH4 is 0-25% range, then please inlet 25%
CH4 calibration gas, and balance should be N2);
c. When calibration gas is filled with gas chamber fully, the real-time concentration will become stable (it may
have little fluctuation which is considered as normal)
d. Input the calibration gas value in the blank (marked as 4 in the above picture), and click SPAN button; (e.g. if
CH4 is 25% calibration gas, then input 25)
e. Then span calibration is finished.
3) Reset
If zero or span calibration are wrong, for example, click zero or span button before concentration is not stable,
or use the wrong concentration calibration gas. Press reset button back to factory button.
