Hello, I am working on ade7758 AC
I have a question about reading the currents register 0x0a _0x0b and 0x0c, why when the current passing through the zero current sensor does not show zero value on the display and it is changing

Hi,
Operation of the AIRMS, BIRMS, and CIRMS registers is detailed in the datasheet. If I understand the first issue correctly, the offset is not as expected. There is a "Current RMS Offset Compensation" section of the ADE7758 that describes setting the offset.

Hi, isn't the offset a constant value, so why does it change so much?
