cootwo O2 calibration expires immediately after turning off

Postby mutex0 » Wed Feb 20, 2019 5:55 am

Hello,

My cootwo's battery recently drained fully. I charged it overnight. When I turned it back on, it displays the standard "O2 Cal Expired" message. The battery charge indicator shows indicates a full battery. I calibrated it using ambient air directly through the unit. The calibration appears to work without issue. The unit turns off after about a minute or two. When I turn it back on, the "O2 Cal Expired" message appears again. The battery indicator still indicates a full battery. However, I have to recalibrate the unit every time it turns off.

Should I replace the battery?

Hi,
make sure that in the My Nitroxbuddy app the "Oxygen Sensor Validation Period" is properly set.
