STPM32 active and reactive measurement results are not consistent.

[Serdar]

Hi All,

STPM32 active and reactive measurement results are not consistent even after calibration. STPM32 evalboard and ST software are used for tests. We have calibrator as a source. Voltage, current, frequency is accurate but active and reactive energy measurements are fluctuating.

Could you please advise what would be the problem?

Do you know a way to get harmonic measurement results?

Thanks,
