MSP430F67641: Inaccurate reactive power

Part Number: MSP430F67641

Hi Team,

The measured active power accuracy is very accurate, and the output will not change greatly.
However, the reactive power of some devices will fluctuate randomly (the occurrence rate is 5%-10% of the total number).
When the value of reactive components is adjusted arbitrarily, or the input is all reactive, the interval between reactive pulse outputs will fluctuate randomly.

Thanks & Regards
