    Default Oxygen Saturation

    My O2 saturation is always between 103 and 104 %. I have lots of surface agitation, plus my skimmer so I am always supersaturated. My problem is no matter what I have my settings set to, it always throws the error "Alarm: The measured value has fallen below or exceeded the alarm threshold." So right now, it is 103.8 and throwing the error. My nominal value is set to 100 and my hysteresis is set to 5. I have the alarm set to active and the max deviation is set to +/- 5. Interestingly enough, when I make the alarm inactive, the error still shows. Is this a known issue or am I just stupid?
    Thanks,

    Can you please post a screenshot of your settings?
    If you temporarily disable this sensor port, save changes, then re-enable, does the alarm come back?

    If I disable the sensor, the error goes away. I can save the entry, reboot the app and when I enable the sensor the error returns. See attached screen shots below for settings.

    ADC 2 = 980 that is much to high.

    So recalibrate? Obviously you know this from your experience, but what exactly is the alarm/error based on? As a user, I am looking at water parameters that would be out of wack... i.e. Oxygen level that is too low.... something like that, as opposed to a calibration number this is not right, as I would have no way of knowing this. (Not sure that it makes any difference but the reading is 930, I'm assuming either way it is too high)
