    How do you keep it from turning off automatically
    So far, it works great very accurate as far as I can tell very responsive picks things up right away. I walked up close to somebody who was smoking a cigarette and it started to respond right away. My only concern is I have no way to figure out how to keep it from turning off automatically After a few minutes, it’s just off and it’s not like it keeps reading in the background as far as I can tell that would be OK if it just turns off the display but it’s not it’s turning off completely. Does anyone know how to stop it from doing that?

    Machine kept saying my CO2 was dangerous and had me worried. So I took it outside in the fresh air and was still dangerous high so I had to figure it was not accurate. I returned it and tried another brand and all is good
