sensor.awi.de offers a wide range of properties. In parts, they can be set per whole item as well as per parameter. Thus, if for example a lower and upper threshold like operation range is available for a whole device, it should be set per item. If the property is valid for a specific parameter exclusively, set the measurement property per parameter.

| Spike_Threshold | 403 | a threshold supplied to the Spike Test as part of the autoQC routine at AWI | a2f788a8-3b56-4067-8755-c1dcdc58471d |
Most of the tests in autoQC are derived from or inspired by Wong et al. (2021) and its implementation in O2A is described in Silva et al. (2020) and Silva et al. (2019). Some details can be found at spaces.awi.de/x/22WjEw as well.

Adding new properties works literally identical for both per parameter and per item.
