STPM32 active and reactive measurement results are not consistent.

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,

BR
