Paul, Al,

I have something like that too. It came with an Amprobe tester kit years ago.

On mine those top leads come off and there are 2 prongs to plug in a receptacle. The Red part on the bottom (remove BEFORE plugging in!!) comes off and it is a 2 prong receptacle. The Appliance plugs into it. One ring is 1x and the other is 10x
