Good morning frnds ,
i am using ADE7763 in my project of Energy meter.i have succesfully made SPI communication between ADE7763 and MCU. and i also successfully got Completed the IRMs part.
but I have some problem in the Vrms register reading and attenuation part.
I am giving Ac Voltage in the range of 0-250VAC. and according to that i m getting mV on the V2P pin of ADE7763 which is as foollows.
as per my readings and data i m getting too much high readings in the range of 0-50VAC.
and second problem is that on the same lower voltage of 3VAC, i m getting different different readings in the Vrms register that creates very big problem in my project.
so please help to troubleshoot the Vrms Part.
