Grounding probes

[SifuMemphis]

Just bought a ground probe on amazon:

Amazon product ASIN B0002DGSWE
I noticed it has this extra cable on it. Is there something specific i need to do with it? Or can I just plug it in, and put the probe into the sump?

the metal ring is for older outlets that do not have a grounded socket.:)

Also, the ring can be used on a cover screw if you don't want to use up an outlet with the plug. Just be sure the utility box is properly grounded for this to work. A multimeter with continuity can test between the screw and one of the outlet's ground ports.
