No stable 0 load or low load
I connected this to a load shedding Arduino Mega at 120VAC and less than 20 Amp loads. The 0 load signal is supposed to be 2.5 VDC however it varies between 2.4 and 2.6 VDC at 0 load. I plotted the variation and there is no relationship with time. It is completely random. A 3.7 amp load can jump all the way from 1 Amp to 4.5 Amp at random. Stable it is not and it is not even useful to determine if a load is present. Total waste of time and money.
