Hey Guys,

 

I have been working on ADE7758 for an energy meter project, when I first powered up the device, the values read from CRVMS register are as follows

 

VCP is 0.110V, value read from value read from CVRMS register is 340768 (decimal) // Vin is 60V

VCP is 0.203V, value read from value read from CVRMS register is 415245 (decimal) // Vin is 120V

 

I am wondering how to relate the value read to the actual voltage at VCP pin?
