How can I tell if the detector is working properly?

Method 1: Place the sensor near cigarette smoke.

Method 2: Burn paper in a small sealed container. After the flame goes out, quickly place the sensor near the smoldering ash. The detector should display a CO reading.

Why does the detector show 0 ppm even though I smell something?

Carbon monoxide is colorless and odorless. The odor may be from another gas, such as combustible gas. Use an appropriate detector to identify the gas.

Why can’t the detector detect CO in vehicle exhaust?

CO is mainly produced when fuel burns incompletely. Modern vehicles with properly functioning engines and catalytic converters may emit very little CO. In open air, exhaust is also quickly diluted, so the detector may display 0 ppm.
