The decreasing error is a nice reminder, and ACTS as a sort of progress meter during long runs. But, the final result is what is impressive.
不断减少误差是个很好的兆头,这至少在一段长时间里所获得的一种进步,且最后的结果必然是深入人心的。

Once again, the RF power meter cannot detect the error.
功率计再一次的没检测到错误。

The metering error considers the non linear effect of the voltage coil and current coil in watt hour meter under different order of harmonics and different distortion degree of input waveform.
