Dear Dlath,
I am calibrating the current channels by following the steps shown in datasheet of ADE7758 page 55. As a result, the channel C is able to get quite an accurate reading compared to the channel A and channel B. However, when no current is inputted into all of the channels, only register value of channel C shows 0 while there are some values shown in the register of Channel A and Channel B. The calibration for xIRMSOS have all been write into the respective registers. Because of this, the results from channel C is quite accurate whereas the results for Channel A and B are a little off. May I know why there are some values shown when current is 0A?
And also, I would like to ask if I can use only 1 channel of voltage as a reference to measure the other 3 current channels? What are the settings that I should make or pay attention to?
Thanks.
Regards,
Kristin Chew
