CO breath test

Postby adam13 » Tue May 15, 2018 3:25 pm

The breath test does not seem to work. I take a deep breath, hold it and then slowly exhale into the Cootwo, but don't see the expected rise to 2-4 ppm. The CO display stays at 0, while the O2 appropriately drops down to 18% or so.

Ignore my post. I got it to work. I had to enable the Higher Resolution in Display Settings, and then the breath test works
