Output Calibration

• Using a kill-a-watt or your own current or watt meter, record the AdcValue output for various loads. It should hopefully be somewhat linear. You can then apply this as a scaling factor to directly convert to watts or current as meets your need.

• If you’re going to use a common torroid for all current transformer modules, you could put the scaling to watts or current into the modified modtronix code upon completion of each line sample. Otherwise it may be just left as unscaled AdcValue and scaled as desired when used for display or recording.
