    I would like to use the cootwo as a standalone, not connected to a smart phone. Once you have calibrated this device, what exactly do you do to test a gas in a cylinder? Do you just "calibrate" it again with the air sensor near an outflow of the gas? Or is there some setting to use to go from calibrating ambient air to measuring O2 in a cylinder?

    It isn't obvious. :)
    1. Hold down button for 2 seconds
    2. While screen shows CAL O2 / ?, press the button again
    3. Calibration will begin for 30 seconds, assuming air as reference gas
    4. Hooray! Calibrated!
