The Earthing Tester checks the conductivity of your Earthing product and ground cords to determine that they are conductive and in good working condition. You simply connect the tester to the ground port of a properly grounded wall outlet 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 Earthing Product.
