Q
What am i doing wrong? it counts down from 120 to 0 then changes modes and sits there. broken? i tried new batteries
Answer Question
A
After the initial countdown it immediately starts measuring CO in parts per million. Mine is very accurate. If yours remains on zero than no CO is detected. If it's doing something weird than maybe it doesn't work. It will not measure CO below 5 ppm eventhough the directs says it will.
