I am working on a project of energy meter. The task is to measure the active energy and then show the output on an LCD. The datasheet for meter IC can be found at the following link:http://www.analog.com/static/importe...ts/ADE7758.pdf
In addition to this, I am using PIC18F4520 microcontroller with this system.
The problem I am facing is that Vrms and Irms values that are obtained in the output are not accurate. Perhaps this is due to the gain calibration Irms and Vrms Offsets. Kindly help me out.
Thanks in advance.
