I have a question,ADE7953 when there is no input signal voltage and current signals, but read AWATT / BWATT / AVAR / BVAR registers, some registers appear FFFFFFFF value, why is there such a phenomenon?
Can you please read all the registers from the 'access all registers tab' and send the information. A Screen shot that captures all the information should be fine.
The following is a screen for read all registers ,The register is equal 0XFFFFFF, it is not fixed in a particular register
Sometimes AWATT and AVAR and BWATT and BVAR register is normal . So I would like you to help me confirm this problem? Thank you !!
Are you always reading FFFFFFFF's on power registers. Do you see the lower bits (2~3) changing with time? FFFFFxxx is a very small negative number so it may be noise.
The energy registers read a zero as they have a threshold enabled by default.
Can you provide a small signal to the inputs and check if the power readings are as expected?
