Calibration of eADE7912 without a load

Calibration consists of applying a gain factor to the calculated values from the output in order to understand what the conversion constants (A/Code, V/Code, W/Code, etc.) of the system are. The measurement will only be as accurate as the instruments that it is calibrated against. This means that for a proper calibration, there needs to be current flowing through the current sensor and voltage across the potential divider which are both connected to the inputs of the ADE7912.

Otherwise the best you can do is take the typical values from the datasheet and approximate those conversion constant values that I mentioned above. Using the values from the "ADC Transfer Function" section on page 20 of the datasheet (ADE7912/ADE7913 (Rev. C) (analog.com)), the size of your shunt and the divider ratio of the potentital divider you can calculate the conversion constant. Then see the spec table on page 5 for the expected gain error part to part to understand how much accuracy shift there can be from the ADE7912 only, this does not include the variations in the sensor.
