Both of these items are good, as well as a VOMETRE.
In addition, I use a plug-in Metre to check voltage, and...
I also made another plug-in voltmeter wired it to a plug such that one terminal is wired to ground, the other to neutral.
When plugged in, it should read zero.
I found a campground power plug-in that Read 120 V.
The plug-in three light gadget confirmed it as miswired.
The owner told me that it had Been like this for 12YEARS, and no one had caught it.
