i am using ADE7763 single phase energy meter IC. i try to read the VRMS register(0x17) from that IC it gives 40960 from that register without giving any input to V2N and V2P terminal. afterwards i convert that value in to real rms value it gives 15v output. now i increased my input voltage to 0-15 there is no variation in the output after 15v output increasing gradually
depends upon input. my output have + or - 5v fluctuation
for eg; i set input voltage as 150 it oscillate between 145-155 what is the reason?
i want only Vrms,Irms and period from ADE7763 .how to calibrate the chip
this one is my part of the code
