This continuity tester for earthing is a handy and useful device that lets you know if your products made for grounding are "really" working correctly. You can use the tester each time you wash your sheets or to test sandals or moccasins to see if you are grounding/earthing. To use the continuity tester, simply connect the tester to the ground port of a properly grounded wall outlet, turn the ON switch and place the tester directly on your Earthing product. Press firmly and a green light will confirm that your product and wire are in good working order. If no green light comes on, press harder and re-check your connections. If that doesn’t work, it is time to replace your product you are using for earthing. This tester kit comes with the tester, 2 AAA batteries and a ground cord.
