How to test your grounding mat

Not sure if your earthing mat is working? We’ll show you how to test it with a multimeter.

[@m300slr]

I went outside with my meter and got 2.2 volts with the ground probe stuffed in the dirt. Then I took my foot out of my shoe and stood on the grass went down to .001. same reading I got in my house. Interestingly i tested this while standing next to my bed and i was 6v and laying in my bed it went up to 12v!! However as soon as i ground myself it goes to zero.. just thought i would add my findings.. thanks for the vid .

[@Omars17]

12v from a bed?!? Yea I gotta get me a ground sheet haha

[@FakeNewsHunter]

Which " ground probe" ? Which metals were involved? Did you multimeter have cupper probes? Do you know that the soil with two different metals put in it or even your body acts as an electrolyte and can form a galvanic element, i.e. a basic battery with various voltages? See the organge- or lemmon battery videos here!

[@LynKramer-u1o]

OHMYGOSH, thanks so much. I had that exact meter you show on the right, and was getting SO frustrated because I couldn’t get it to show my bodies voltage. I watched countless other videos for days until I came across yours. I really appreciate this. :)

[@bethhepting2727]

I bought the exact multimeter you have (Klein Tools), and I cannot get it to show my "natural" voltage. I followed your instructions exactly and it never moves from zero. 😞

[@DetoxMorgellons]

Mine keeps saying zero too

[@TheTonyamgraf]

Same here

[@theforexation]

[@Merializer]

That 2 volt is not your natural voltage (2:21), it's from electric fields from cables in the walls emitting into the room and your body picks that up.

[@dbsean]

Interesting point. Though that's not to say grounding that voltage isn't potentially a good thing vs. being ungrounded and harboring that constant charge within your body, right?

[@Merializer]

Thank you, thank you, thank you! My mat works and now I know it thanks to you:)

[@s.l.7982]

Thank you for cutting to the chase. Many videos give long proloques and it's very frustrating. I just found the multimeter in the garage and needed to know (right away) if the slate in the back yard is grounded because we have artificial grass. I was not sure what setting to use so now I know. Thank you!!! Update: it didn't work. Everything is reading zero - even when I plugged it into the wall.

[@DetoxMorgellons]

That’s my problem. I plug everything in but it still says zero. Is that how you know you bought garbage?

[@4fire1]

How do we test the voltage on a mat with a copper rod buried in the earth method? Not using the ground outlet as I presume I have dirty electricity in my home

[@jimmysmad]

Ive grounded my bed. Meter is showing 00.03 is that ok or does it have to be 00.00?

[@chrisparker7400]

Wait for someone who knows more than myself but that tells you that your outlet is not a good grounding connection. Try a different outlet and see if it’s the same. If your house electric is grounded correctly then it should read 0. I would run a copper pole in to the ground and a copper wire up the side of the house and connect that way to your earth mat instead of using the plug in your house.

[@jimmysmad]

@chrisparker7400 OK cool. Thanks for getting back. I'll do all that, hopefully be on 0

[@jnantomahify]

Do me a favour n pls share with me which multimeter brand are u using bud?

[@dbsean]

Even if it's not perfect (00.00) I suspect 00.03 is still better than whatever reading you're getting without being in contact with the grounding mat?

[@genohamata7380]

Thanks for your video. I was having the same problem with a multimeter and I thought I was doing something wrong. It is good you showed it was not the grounding mat but the multimeter that was the problem

[@skarath]

What is actually taking place is the multimeter samples faster than your 60 hertz household electric supply. The 2 volts you measured is the charge induced on you by that 60 hertz EMF (from just being near a lamp etc). Grounding repels low frequency EMF. So yes, it is a way to check you are grounded. This method will not work if you are not near 60 hertz EMF fields.

[@dbsean]

Great comment! Makes sense. I guess the million-dollar question is... are we better off for grounding those 2 volts our body is harboring vs. not?

[@ericcollins6231]

Dang, I specifically bought a Klein, supposed to be a good brand, nearly identical to yours, just so I wouldn’t run into this problem. And…. I’ve run into this problem! Works on testing the voltage of the outlet. But get absolutely nothing when trying to test myself.

[@mistywilliams7801]

What’s it mean when it volts up instead of down? Tried this with two people and it volts up

[@montiesz]

I’m not sure I understand or agree with the idea behind what this test is actually measuring. The first thing I would do is to check and make sure my safety ground is even earthed by measuring continuity between the hot blade of the outlet and the safety ground. if there is continuity there, I would then check someway to see if there is continuity between the very tip of the metal plug of the mat and somewhere on the mat. It is interesting that the value on the multimeter changes when you touch your hand on the mat, but I’m not sure how that is working

[@michaelflores572]

If I was to stick the black lead into the ground outside and touch the read lead to myself while wearing rubber shoes will I still get the reading of 2 volts?

[@66gmoney]

Good question

[@dbsean]

essentially, yes. I did this test and had nearly identical voltage readings outside as I did inside, though I was still in close proximity to the house on a patch of grass beside my garage. Apparently, the body acts like an antenna and so the voltage its harboring will eventually drop the further you are from electrical devices.

[@kurgan88]

Tested it with the similar mat, but connected to the outside rod in the ground with an 8 meter wire. And it actually works just like in the video. 👍 Read somewhere that it might be harmful to ground yourself through home's outlet since it picks up EMF and whatnot.

[@ayoungtricknamedjim5498]

I bought this same Klein Tools meter based on your recommendation and it doesn't work. It does the same thing that blue one does (just shows 0.0 no matter the circumstance).

You only touch the earth slot on the power supply.

[@joephu]

Almost perfect but you actually need an auto-ranging multimeter so it can read millivolts (mV). You are probably not zero V but a very low mV.

[@wildwest9395]

Right on, was wondering why I didnt drop to zero. My auto ranging MM dropped me from 2.8 to .12.

[@B.E.C.K.]

Multimeter. Available on Amazon, Home Depot, hardware stores, etc

[@jg4719]

The mat was already connected to the same ground. The test makes no sense.

[@Snowsea-gs4wu]

It makes sense because it shows the difference of potential between the (common) ground and the body when not touching the mat, and then shows that potential falling when touching the matt that is connected to the (same) ground. Hope this helps!

[@littalwabbit]

Why does my meter go to zero even grounding mat isnt plugged in?

[@chadhibbitts9791]

Could you just touch the black lead to the grounding mat instead of into the ground outlet?

[@loumarcellino17Q19]

Thank you for this information. I am a big fan of grounding and use grounding mats when I am not able to naturally ground outside. May I ask you please... I have heard many suggest that plugging a grounding cord into a ground port, still allows electrical current to flow through the cord into the mat, and that the multimeter test is not accurately showing the electricity flowing into the cord and mat. Using a grounding rod outside is not something I am able to do, so I have no choice but to use a grounded outlet. One YT video showed high voltage readings in both the cord and mat when using the standard cord. This particular person developed a "Pure grounding cord" which has a filter at the end to shield the entire cord from ac current and EMFs. When using an electrical meter to test both the standard grounding cord and the pure cord, the meter sounded off a high reading of voltage in the cord as well as the mat, while the pure cord had no reading. For those that are electrosensitive, the pure cord is a great option, but for anyone wanting to ground themselves, this pure cord is said to protect from ALL electrical and emf radiation and allow ONLY the pure electrons from the earth to your body. Others suggest the grounding mats (assuming standard cords) are even harmful, but many report relief or elimination of symptoms using the regular cords and outlets. I just get more confused the more I read up on this or watch videos on this. I was wondering what your thoughts are regarding this? Thank you for taking the time to read this.

My voltage shows as 0.2 before I touch the mat. Why is it so much lower than yours?

[@makaela3041]

I think I have the reverse, if I touch the mat, it be like 0.2 or 0.1, when I don't touch mat just holding red prong, it will be 0, and when the red prong was swirl aggressively in air it also picks up 0.1

[@aquamoon4401]

Ok I have the equipment but I don't want to die being an amateur. I need another way to test this mat lol

[@makaela3041]

I tried this and have the UK plug, but I turn multimeter a to 500, since UK plug measures 240v, but my reading is 0...why tho

[@mj9949]

Hand on mat shows 0.2. Does that mean mat not grounding? Is mat usable or throw out?

[@mumbles1justin]

when you test like that your basically shorting the leads through the receptacle only because the ground prong is internally connected to each other. The 2v you see on one meter and not the other is ghost voltage do to high impedance of the Klein meter. The other meter just has a lower impedance frontend blocking the ghost voltage. So I don’t know if this actually testing anything. You could just as easily tested continuity from the mat surface to the tip of the grounding wire from either multimeter and gathered the exact same knowledge you would get running the test in this video.

[@1979utuber]

couldn't you just touch the receptacle ground to the mat in ohm so it beeps so it creates a circuit to show if it's working?

[@mumbles1justin]

@@1979utuber That is a continuity test. That setting though probably wouldn’t work because it requires a higher resistance to trigger the beep and start to read a measurement. The ohms setting would be better. But keep in mind that still wont tell you how good the ground is .

Probably worth test continuity from your ground outlet to your ground stake outside as well. I know older houses ground and neutral are connected together in the breaker box.

[@focusdude88]

Thank you for saving me time. Mine doesn’t work.

[@drewcharley1635]

Hey. Electrician here. Do this same test except I want you to turn off your main breaker at your electrical panel. You’ll find that grounding conductor that is connected to your receptacle is run parallel (along side throughout the wire raceway) actually “picks up” voltage (harmonic voltage) from your ungrounded conductor. Meaning when you touch that voltmeter to yourself and the grounding conductor you read that harmonic voltage. When you touch the Mat it would clear that reading. It’s not “your voltage”. Test it with the main breaker shut off, and you’ll understand

[@sdowen12]

Are you saying that with breakers off the readings would all be zero no matter what? How can you determine the readings are from the "harmonic voltage" around the grounding rod vs from ambient emf's in your environment affecting your body (turning off breaker would likely greatly reduce this)? Could you replicate this test without shutting off your breaker by testing with rubber boots outside and with a grounding rod? I'm also confused if the grounded conductor is picking up harmonic voltage from the nongrounded conductors then is it really grounded? Shouldn't all that electricity be going straight to ground?

[@dbsean]

If what you say is true, how was I able to replicate essentially identical voltage readings / results with the setup in this video when doing the test both inside and outside? Outside, with the multimeter black probe jammed into the ground while holding the red probe in my fingers I was getting nearly identical voltage readings to what I saw inside with the black probe plugged into the ground in the wall outlet. When I removed my sandals and stepped barefoot on the grass, the voltage dropped to zero.

[@Vera-xu3xw]

If it drops to zero, it's still zero.

[@dbsean]

@@Vera-xu3xwbecause by touching the mat or the ground you’re effectively shorting the circuit on the reader by completing the chain… your charge isn’t zero, the device shows zero because it isn’t capable of reading anything because you’ve shorted it. It’s not a proper scientific test.

[@Vera-xu3xw]

@@dbsean I'm pretty sure it's still zero 🤣 You can get the same results doing the test outside, actually using the ground.

Notes : How to test grounding matt Connects into grounding outlet - using ions not electricity. Use multi meter. It can actually be that your multi meter doesn’t work properly. This matt wasn’t working for me before, this I bought another one a never one and it works just thin. Show you how to do this. Take it to voltage side ways voltage AC current with swigililng swinging link ~ Can test your matt - by doing this - plug into ground outlet. Touch - plug into ground outlet - now you can see my voltage is two volts, I have voltage of two volts. So black wire goes to ground, now watch this - as soon as I touch ground it has reduced my voltage to zero, takes hands of fit, now will show you this one, it just doesn’t work, doesn’t show my voltage. Take this and put it prongs not suppose to put it in. Only shows low voltage. Q myself time noticed- I don’t have type of outlet shown in video here, but have UK version, how do I do it UK version?

why does my Klien Tools multimeter say that my body charge is only 0.5-0.9 depending on where I measure (my bedroom is at 0.9 and my kitchen shows 0.5)😱. When I touch my grounding sheet, it does go down to ZERO - so that's great! what am I doing wrong? Or are my batteries running low (which may explain my low energy! lol)

[@BebeBonet]

This is the worst tutorial ever.

[@daifeichu]

The reason the yellow meter shows the voltage is because the inputs of that meter have a high impedance. The input to the blue/green meter has low impedance. At a point in a circuit where there is high impedance you will have high voltage and low current. At a point in a circuit where there is low impedance you will have low voltage and high current. I have a Fluke meter that cost a lot of money, around $800, and it will not be able to do this ground test because the inputs are low impedance.

[@AllSectorsHearThis]

I found that the earthing worked through a fitted sheet for my grounding sheet if my bare skin was touching but not if clothed skin was touching. My pillow case may be redundant.

the mats are not low resistance . but rather a higher resistance and not purely low resistance. most types of mats have a resistor inline eather in the plug or wire . it doesnt need to be low resistance to work , it only needs to bleed off a little charge at a time . and most multimeter beep functions have to be at a fairly low resistance to beep . depending on where u test ur mat or bed sheet if u have grounding sheets u may reed a few 1k ohms and thats fine but ur meter wont beep
