Calibration
- read the current values of UgainA-C and IgainA-C at http://<IP>/status
- connect all three voltage inputs and current transformers to a single phase
- use a large resistive load (eg. a kettle) as a load, also measure the current and voltage with a regular multimeter
- calculate the new values for the six gain settings by comparing the values reported by the device and multimeter and adjusting the gain settings accordingly
- set the new values by requesting this url using a browser or curl (change igainc and the value to what you've calculated in the last step): http://<IP>/set?addr=igainc&val=20037
