I need to calibrate phase for the ADE7953, as I am using a current transformer and want to collect power data. The current transformer is connected to channel A of the ADE7953. For phase calibration, according to page 12 of the AN-1118 document, I need to measure active energy. And to measure active energy, I need to set the accumulation time to 1 sec. To do that, I enabled the line cycle accumulation mode, and set the line cycles (register 0x101) to 120 (since the frequency of my voltage waveform is 60 Hz). Then I try to read the Active Energy A (register 0x31E), and I get a 0, regardless of what I set the voltage supply to. I am not sure what I am doing wrong. I am able to read the Vrms and IrmsA just fine.
Thank you in advance for any help.
