Continuity Tester to test if a grounding product is indeed grounded. Snap one end of the grounding cord onto the continuity tester and plug the other end into a grounded outlet. Then, place the continuity tester onto your grounding product and press the button. if the light remains green as you move the tester over the surface of the grounding product then that means it is successfully grounded. Please make sure the grounding product being tested is also plugged into a grounded outlet.

Review: A very useful piece of kit - Works as it’s supposed to. I have used it to check which of my grounding devices actually work, which is most of them apart from one. I have also use it to find which floor surfaces in my home are grounded. So I now know that I can stand on the kitchen floor or the slate fireplace hearth and will be grounded. And just for fun, I have taken it out and about with me to confirm that I am grounded when standing in the garden barefoot, or when wearing boots but touching a tree or any other living plant or grounded person. Also any metal object embedded into the ground, such as a lamppost. Confirmed that concrete is also grounded, but not asphalt. A very useful piece of kit.

## Features

- 🌎GROUNDING: Grounding uses the earth's natural energy to improve health and well-being. The earth carries a slightly negative electrical charge. When you come into direct contact with the earth, either by standing barefoot or by using a grounding product, this charge is transferred to your body. In your body, these negatively charged free electrons work as antioxidants which neutralize the harmful free radicals and helps you to realize many health benefits.
- 👣HOW IT WORKS: Snap one end of the grounding cord onto the continuity tester and plug the other end into a grounded outlet. Then, place the continuity tester onto your grounding product and press the button. If the light remains green as you move the tester over the surface of the grounding product then that means it is successfully grounded and there is continuity. Please make sure the grounding product being tested is also plugged into a grounded outlet, or you will not have continuity.
- 👣WHATS INCLUDED: Our grounding continuity tester includes one tester with battery included, as well as a 15 foot grounding cord which will allow you to properly test for continuity, and can serve as a back up or replacement grounding cord for your grounding/earth connected products.
- 🔋BATTERY INCLUDED: One battery is included inside of the continuity tester. The tester is ready to be used once connected to a grounding cord!
- 👣INSTRUCTIONAL VIDEO: Please refer to the video in the product pictures for a guide on how to use this continuity tester.

## Questions & Answers

**Q: Has anyone used this outdoors to see if their concrete or brick paver patio is grounded?  I realize it requires an outside outlet.  Anyone tried?**
A: The tester can be used outside where no outlet is available--using the actual earth/the ground under your feet/soil/dirt.   I do not know why this is not mentioned in the instructions.  Think about it like this....where does your electrical outlet get its "ground" in the first place?  Somewhere along your electrical box is grounded into the earth somewhere.   Dirt works just fine without using the grounded hole in your outlet.  (Remember to test your electrical outlet for proper grounding first.)
Again, no electrical outlet outside-no problem, as long as you can reach some soil/dirt/ground somewhere.
Just stick (or plug) the end that would normally go into the grounded hole of the electrical outlet into the dirt/soil/earth-it will be grounded.  
I found that my sidewalk and driveway are only grounded when wet but the garage floor has a good ground regardless.  Both areas tested using my hand as the test subject to see if I was "grounded" while standing barefoot on each surface.  I also tested my mats using the grounded outlet indoors and again with the ground end in the actual soil outside...both gave the same results.  Grounded.
I also added a piece of copper wire all the way around one of my sandals but not the other.  Then lifted each foot to see the results.  The copper wire worked to ground me, and my kid wearing tennis shoes while we held hands-as long as the shoe with the copper wire was on the ground...or in this case, standing on the grass.

**Q: why is it that when I hold the metal tip of and put the square part on my skin it says I'm grounded, no matter where I am or touching the mat or not?**
A: If you hold the tip and also put the connector on your body you are creating a continuous circuit - therefore you are testing positive for continuity.

**Q: When i stick the grounding cord in the ground / earth, i want to keep it clean.  can i wrap the end in aluminum foil before i stick it in the ground?**
A: Yes. Metal on metal; it's okay.

**Q: What diameter is the connector pin/socket?**
A: Thanks for your question. 4.8mm
