Putting a Line Voltage Multimeter in a Receptacle Box (VA4K vs Shogun Test)

I got a Volt/Amp/Watt/Wh Meter from Banggood and wanted to put it to some use. So I decided to stick it in the back of a receptacle box, making some kind of metered extension cord.

This video shows the process of doing that, but is also a test of the Blackmagic Video Assist 4K vs. the Atomos Shogun for a review I’m working on. It’s a literal side-by-side comparison of the two. Though there’s no difference in quality (there shouldn’t be — they were both recording in ProRes HQ via SDI), I recorded about an hour of footage and neither one showed dropped frames or sync issues during that time. So far so good.

More to come on that later..

  1. I’m not an electrical engineer (wait, I am sorta). But I think the discrepancy in the current reading has to do with “power factor”. A motor can appear to use less power when you just multiply current and voltage. Because magic. Maybe the kilowatt factors that in.
