There's not a lot to say here — obviously, this is the reading you want — but I'd like to stress a point that I've made in other JLC articles. When wiring a receptacle, never use the push-in type connections that come on the backs of some receptacles. These are not reliable; they may work loose over time. Always use the screws; otherwise, a "Correct Wiring" indication one month may result in a dangerous situation the next month.

Loop the stripped end of the wire around the screw and tighten it snugly. Make sure you loop the wire so that it gets tighter, not looser, as you tighten the screw.
