ADE7953 Unstable CF Output

I am using ADE7953 for measuring electrical energy. I am using a CT for current measurement. I designed the schematic as described in the application note AN-1118. I calibrated the meter at 220 V 10 A, unity power factor. But the error in CF output increases with increase in load and with time. Any idea why its happening and what could be the solution?


Thanks in advance
