Rid-Vold Titanium - Aquarium Grounding Probe

Makes sense! I'm a little confused then - on my multi-plug both "slits", when connected to ground, read 120VAC - what does that mean?

Now I’m a bit confused... If your power strip/extension has multiple things plugged in, you may get a reading on the multimeter even if you are testing neutral and ground at the same time since electricity is being used by whatever is plugged in. Best is to test the wall outlet straight without anything plugged into that particular outlet.
