Query regarding ADE7758 GAIN Register (0X23)

Hi,

Am working on ADE7758 & my application is simple voltage & frequency reading.

So far, I haven't starter testing on the prototype board, and am not understanding the purpose of the GAIN register (0X23).

In datasheet, we have got AVRMSGAIN, BVRMSGAIN and CVRMSGAIN. Then why do we really need GAIN register?

 

Again I didn't really understand like how to set the ref. voltage between 0.5, 0.25 and 0.125.

 

If anybody could help me with this, then would be a real time saver.
