Continuity Product Tester

Continuity Product Tester


Earthing Connection Product Tester Details:


The Earthing Connection 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 it directly on your Earthing product. A green light will confirm that your product and wire are in good working order.


  • Product tester with 20-foot (6.1m) coil cord
  • Splitter

How to use it:

  1. Insert the prong end of the plastic splitter into the grounded outlet or the ground rod cord.
  2. Plug the Earthing cord from your Earthing product (such as sheet or mat) into one of the two splitter receptacle ends.
  3. Insert the prong end of the tester cord into the other splitter receptacle.
  4. Place the product tester flat on your Earthing sheet or mat. The round metal plate must be in contact with surface of the sheet or mat. Press firmly, particularly on the sheet, to obtain a good contact. A green light means that the sheet or mat is in working order. In the unlikely case that no green light comes on, the sheet or mat may be defective or may has lost conductivity.
  5. Disconnect splitter from the ground connection. Disconnect cords from the splitter.
  6. Re-insert Earthing cord from sheet or mat into ground connection.
  7. You don’t have to test your sheet or mat often. Perhaps after cleaning/washing. The more you use the tester, the sooner the batteries in the tester will expire

Helpful Tip:

Sometimes, people have difficulty testing their sheets. Please try the following:
If the light doesn't come on, place one hand on the sheet while holding the tester in the other hand and with one finger on the silver button on back of tester. A green light would show that the body is grounded when touching the sheet. Make sure that both the tester and the sheet are plugged in to the ground, as described above.
The reason for perhaps the light not going on may be that you aren't pressing hard enough on the tester. The surface fabric of the sheet sometimes prevents the button from contacting the conductive silver fibres of the sheet. The surface seems smooth, but if you were to look at it with a microscope you would see "hills and valleys." The pliant surface of the skin, unlike the hard metal button, will bend around fibres and make good contact.  You can also put some moisture on your finger tips to create a better contact.
