5.4 Nguji Detektor
To verify the CO detection function, expose the device to a small amount of carbon monoxide. A common method is to bring it close to a lit cigarette or burning paper that produces thick smoke. The CO concentration on the screen should increase, and the alarm should activate if levels exceed the threshold. Do not test with car exhaust or in overly airy places, as low CO concentrations may not trigger the sensor.
