The readings from my O2NE are stable unless I tap / bump the device, they then change by a large amount. Why is this?
The O2NE+ and Safe-Ox+ are both sensitive to mechanical shock, if your device has been dropped prior to installation or has experienced a large mechanical shock, the Oxygen detection cell may become stable. From the sounds of your device symptoms it may have suffered a mechanical shock. Please return your O2NE+ to Analox for investigation and repair.
