Mystery device - continuous waveform


#1

Anybody seen a continuous waveform like the pictures below about 7 cycles/minute, amplitude around 300W ? Lasted most of the day… I originally thought it was a powered sub-woofer cycling between off and on (it has an auto on feature and has been turning itself on with a 60Hz hum). But after a little more investigation, traced it to a slo-cooker crockpot thingy.

Very cool. We use our crock-pot fairly frequently, particularly in the winter, but Sense hasn’t detected it yet. Fingers crossed.
