How does it get the results? How about with a variable load?



The ST3/XT3 can display instantaneous RMS reading for voltage and current. 

The hardware within can get an averaged RMS over 12 cycles at 60 Hz and we could also run a moving average over a bigger set of RMS readings to reduce the effect of load fluctuations.
