ADE7880 使用单相问题

Thread Summary

The user is experiencing issues with the ADE7880 not reading correct voltage and current data. The final answer suggests that the reference voltage source was incorrectly set to 0.5V instead of the standard 1.2V, which was corrected in a hardware revision. After the revision, the user still observes non-zero VRMS values for VB and VC, which should be zero when these pins are left floating. The support engineer recommends checking the AGIAN gain register settings as a potential solution.
