Yes, the sensor I linked and had a photo of in my first post. The voltages I am seeing don't match up with your calculations. Maybe the burden resistor on the board is different then what was listed in the specs. The RMS voltage on my scope matched what I was seeing on my DMM.
Although one odd thing I noticed is some of my test-load devices gave me weird readings. My heatgun drew 8A on low, but the sensor showed less than 1v. When I switched the heat gun to high it draws 11A, then sensor was showing 3v or something. So that's weird right? The waveform on the oscilloscope looked odd too, less "spikes", which I think would lead to a lower RMS voltage.
