I and my friends are making a project using an Arduino UNO and the energy meter ADE7753 and we found an Arduino library for this chip, but we aren't quite sure if this library is giving us the right values of energy (Or we don't know which constant to use to converte the value given to the real value) and we also are having troubles to calibrate Phase, Watt Gain and Watt Offset (We are using an accurate source to do this calibration). We are using a hall effect sensor for measuring current and a transformer for measuring voltage. Any help is appreciated!
