At this time, the display light will light up green, indicating that the carbon monoxide sensor calibration test is qualified. When the carbon monoxide methane gas test value of the carbon monoxide sensor remains unchanged, the display light will light up red, indicating that the carbon monoxide sensor calibration test is unqualified and needs to be repaired.
