When the im1253b module is actually measuring, why is the measured voltage and current multiplied by the power not equal?

Answer: the calculation formula of standard active power is: voltage x current x power factor (uxixcos Φ), Never lower the 

power factor. Our electric energy measurement mainly measures the active power, and the voltage x current is the 

apparent power.
