Thanks, that's what I wanted to hear. I'm going to have to learn to use
mine "better" before I plug it into high voltage...

Only 120v use, but I carry one of these in the toolkit in my truck at all
times ... and in my pocket during electrical inspections in houses I'm
building. Mostly to insure that circuits are live and wired correctly, but
also to verify to an inspector that a circuit is indeed GFCI protected
(you don't always know where the GFCI receptacle upstream is located)

Hmm...I have one of those too. The fine print at the link says "not for use
with Ground Fault Interrupt -GFI outlets".

Sorry, I grabbed the wrong link. This is the one I have:

And a cheaper one that does the same thing:

http://inspectusa.com/receptaclegfci...ors-p-123.html

The GFCI outlet/receptacle itself (it has its own, built-in test circuit).

The other one is used to test that same built-in test circuit in the
GFCI receptacle, but FROM those receptacles which are on the
"downstream" side (those coming off the "load" terminals on the GFCI
receptacle).

So you show an outlet is GFCI protected by checking another outlet
downstream (I've read that a GFCI breaker
is often put on the first outlet off a line)? So, I take it that of the
device an outlet properly grounded, and it's not directly grounded, then it
must have been done upstream with GFCI? GFCI is one of those things I need
to read up on...

You can use a GFCI receptacle in an outlet by itself, or use it as the
first one inline in a circuit (power in connected to the "line"
terminals; power out connected to the "Load" terminals) to protect the
other receptacles "downstream" of it.

Read up on it ....
