ADE7753 Calibration

I am working on a project of a energy meter with ADE7753 and Arduino UNO.

I am using the Honeywell CSNF161 as a current transductor and a simple voltage divider to obtain the voltage signal.

Actually, i am reading good values of voltage and current from VRMS and IRMS registers, but i noticed that when no current is applied on the current transformer, there's still some offset on my IRMS register.

I need some advice to calibrate my ADE7753... What register should i calibrate first and how i do it.

I'll post my schematic below. Sorry for my english.
