ADE7953 VRMS

Question asked by angle9 on May 3, 2017

I develop a power meter using ADE7953...
Connect to MCU using SPI interface..

 

I read VRMS register with no voltage applied to the input pin...

I read 0xCF070000

 

Then I applied 230 VAC with no Load and I get 0x73070000

 

Is this the correct value?

 

I attached schematic of voltage channel

 

Thanks
