Wait for the reading to stabilize. ②Smoldering paper test: Light a piece of paper or tissue, extinguish it quickly, place the smoking paper or ashes in a sealed container, and use the detector to check for smoke. But do not bring open flames close to the detector, as high temperatures can damage the device's sensors. FAQs： Q: Why can I smell carbon monoxide, but the device isn't detecting anything? A: Carbon monoxide is a colorless, odorless gas, so the smell you're detecting is unlikely to be coming from carbon monoxide. The smell may be caused by a leak of another gas, such as natural gas. We recommend using a combustible gas detector to identify the source. Q: Why carbon monoxide cannot be detected even when there is a source of combustion? A: Not all combustion generates enough carbon monoxide to trigger the detector. CO is produced only during incomplete combustion, and in well-ventilated areas or with complete burning, levels may be too low for detection.
