Well explained, thank you! This is the only video I found where I could recreate the test myself quickly and easily just from following what you did. Great job!
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. :)
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 .
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!
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.
Well, fortunately this guy taught us how to know our device is crap. I just bought my testing device today, and while playing with it, it flickered and died. SIGH. Back to the hardware store.
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
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.
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.
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.
I made my own, I drove a ground rod into the ground outside, ran a wire through the foundation vent up through the floor in my bedroom, put an alligator clip on the end of the wire and attached it to a sheet of copper fabric which is under my bed sheet. I have verified that it is conductive, but my cheap multimeter can't perform this test. Tonight will my first night sleeping grounded.
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. But I use it in the office chair next to my bed. If I'm wearing clothes, I tuck the earthing pillowcase under my shirt against my skin. I am sleeping better.
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?
So in the living room the test says 0.4 and in the bedroom 0.0. my husband is 0.1 in the bedroom. This is without the grounding sheet. Does this mean the test is not ok, or that we are really grounded and don't need the sheet😅?
@@gcampbell6167 TH-cam/Google makes it hard/impossible for me to write good responses with useful info these days. It's best to educate yourself through my stuff.
Thank you for the great video. I wish I had seen it before I ordered the blue one in the right and it’s not working. I will definitely send it back to Amazon, but how do I find the right meter to see if my grounding mat is working or not? The one you are using is too expensive for me for just one use :(
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
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. 😞
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?
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.
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.
I have the same problem, did you find in the meanwhile why the device on the right does not work ? The one on the left is really too expensive to just test a grounding mat. Thanks.
Thank you for educating that not all multimeters are the same I guess some are only meant for high voltage While others are more sensitive to lower voltage
Thank you - I tested with 2 meters and I read 0.854 on each : Is that 0.8 v ? Mine doesn't have a 200ac setting but an Auto : I'm using both a Southwire 22070T & a cheap EXTECH. Funny thing was I was worried my Laptop was causing me issues, and found out the casing is also grounded.
I just bought a voltage meter and I can’t tell if it doesn’t work or if my house is just not properly grounded. I have seen some old houses like mine that have three prong receptacles but the ground is not actually connected. I can’t find a single ground in my House that registers any voltage connected to me. But then again it might be the voltage meter… It’s brand new but it may be like that other voltage meter you featured. I guess I can go outside and stick it in the dirt and see if that works. If it doesn’t show then I know it’s the meter and possibly not my house.
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 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 .
@@mumbles1justin I got the beep to work on my homemade mat the one I got from amazon was a scam. You can also test continuity from the mat to the ground on another nearby outlet. 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.
The only way you’d “die” is if you shoved the METAL probe into the wrong hole in your outlet. If you live in the US (or any other area that has the same outlets) and you have a 3-hole outlet like what was shown in the video, the two slits are where you DONT stick the metal probes. The single hole at the bottom is where you stick the probe. Theres no electricity coming from there. However, if you’re too scared still, then you can just do exactly what was done in this video except go outside and stick the black probe into the earth instead of the grounding port in your outlet. It should work the same way.
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).
Can you tell me the model of that multimeter? I was going to get a Klein MM420, which has a few more buttons, that was recommended by someone else. Just double-checking.
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.
Technically, if your mat is plugged into the ground port on the receptacle with the included white wire, you should really be able to check continuity from the mat to the other ground port with the meter and it should ring out, correct?
I thought the same continuity would be a better test, I would also test continuity from your ground pin in your outlet to the ground stake outside using test leads
How do you test without a grounding outlet? My house is not grounded, I’ve had to run my lines outside but the only way I had to test was with 2 of the connectors for the products… I’d like to test without using the connectors because I’d have to disconnect one of my products
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
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?
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-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.
but if you do this with barefoot on grass it should show negative so does this say the matt really doesn't work nearly as well as being barefoot outside (on a conductive surface of course)?
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
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?
There’s this search engine called google that might help answer your question. In fact, it might help you find other answers and useful information. Not to be a smart ass but do people really not use search engines?
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)
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
I have measured the connection from ground in the outlet to the the end of the cable connecting to the mat, so basically just the cable the the cable testing function, you know the beep, same way I test all my audio or electrical cables. There is no beep, so no connection !?!?. In both the cable for the matt and the one from the bedsheet. How can there be any effect if the cables are not conductive ???
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
My wife and I did this test and we get 0 volts, tried multiple power outlets and the soil outside. I know my multimeter works as I’ve used it many times for testing outlets and batteries. I guess it’s rare to have voltage in your body?
Assuming you have it on AC, I've also experience this and am not sure why I'm getting higher volt readings when I plug the black probe and the grounded mat into the same wall outlet. I found if I plug the black multimeter probe into a completely different wall outlet's ground than the outlet the mat's plugged into, grab the red probe and step on the mat - then the volts go down, well below what they are without contacting the mat. Have you tried this?
@@TerraPMats problem is my mat is 100% grounded, but Whenever I touch it, I feel not great. I attract all emf signals including wifi radiations. I think it's not good for my health. I think I wasted my money buying it
I would say that you should be measuring resistance not voltage. The DMM with 0.0 on the 200VAC range could be within spec since probably doesn't auto-range and the resolution of your 3.5 digit display at the 200 range is 1%, or 2 volts. Set your green/gray DMM to 200V DC and check a AA or AAA battery. Do you get a proper reading, if not set it to 20V and check again.
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.

I just got a brand new Klein Tools, same one you have, and it's showing 00.0 not registering anything when I measured the voltage in me. 😩
Technically, if your mat is plugged into the ground port on the receptacle with the included white wire, you should really be able to check continuity from the mat to the other ground port with the meter and it should ring out, correct?
I thought the same continuity would be a better test, I would also test continuity from your ground pin in your outlet to the ground stake outside using test leads
Continuity won’t show as the cable will have a 100kohm resistor so you’ll get a false reading, instead test with the 200kohm setting on your meter.
How do you test without a grounding outlet? My house is not grounded, I’ve had to run my lines outside but the only way I had to test was with 2 of the connectors for the products… I’d like to test without using the connectors because I’d have to disconnect one of my products
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
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?
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.
If it drops to zero, it's still zero.
@@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.
@@dbsean I'm pretty sure it's still zero 🤣
You can get the same results doing the test outside, actually using the ground.
My voltage shows at 63, can it be correct? Compared to yours it's a huge difference!
but if you do this with barefoot on grass it should show negative so does this say the matt really doesn't work nearly as well as being barefoot outside (on a conductive surface of course)?
Thank you for this simple, elegant explanation 🎉
What does it mean if the numbers go up when I touch my grounding pillowcase?
Hi. Do you know if a grounding sheet attracts EMF ? I can't find any information about this question.
What brand are both
Thank you!!
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
Well done! Thank you.
Could you just touch the black lead to the grounding mat instead of into the ground outlet?
which Klein mulitmeter is this? thanks
Hand on mat shows 0.2. Does that mean mat not grounding? Is mat usable or throw out?
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?
Thank you for saving me time. Mine doesn’t work.
So ideal to get 0 voltage ya, so when working on esd mat, with wrist band how do I test so that my reading is 0
Awesome thank you!
Did I buy a lame multimeter? It seems you get numbers when touching the red, but when I turn mine on it doesn’t say anything
One question: Why on voltage for 200?
is this exactly the same process for uk? im not even getting a reading testing the current through my body , brand new multimeter .. thanks
UK earth is the top prong.
Great I have 2 that don't work how can you tell be fore you buy?
Using a klein tools mm 300 and all I get is a flashing negative sigh and 0.00….any advice?
Which mat is that?
Where do we get one of those multi meter testers?
eBay.
@@goldenjordan Thanks.
There’s this search engine called google that might help answer your question. In fact, it might help you find other answers and useful information. Not to be a smart ass but do people really not use search engines?
Thank u for this !!
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)
Why does my meter go to zero even grounding mat isnt plugged in?
thanks!
So this multimeter here has no 200, but 600m, 6000m , 60v, 600v...tips?
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
how to do this test when ground goes outside thru your window? i dont gorund thru plugs. thanks! :)
The exact same way. The ground plug in the wall outlet is simply connecting into the ground.
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
Thanks!
Thx buddy 👍
I have measured the connection from ground in the outlet to the the end of the cable connecting to the mat, so basically just the cable the the cable testing function, you know the beep, same way I test all my audio or electrical cables. There is no beep, so no connection !?!?. In both the cable for the matt and the one from the bedsheet. How can there be any effect if the cables are not conductive ???
The cable may contain a resistor. Typically 1M Ohm. To reduce current. I=V/R
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
what if we are using a grounding rod?
Why would you set the dial on 200 volts just to measure 2 volts. Shouldn't dial be on 20 volt setting only to measure 2 volt??
My voltage shows as 0.2 before I touch the mat. Why is it so much lower than yours?
My wife and I did this test and we get 0 volts, tried multiple power outlets and the soil outside. I know my multimeter works as I’ve used it many times for testing outlets and batteries. I guess it’s rare to have voltage in your body?
I used the exact multimeter on the left. And my voltage INCREASED when i made contaxt with my grounding mat. How is this possible?
You may have it on Direct current and not alternating..
Assuming you have it on AC, I've also experience this and am not sure why I'm getting higher volt readings when I plug the black probe and the grounded mat into the same wall outlet. I found if I plug the black multimeter probe into a completely different wall outlet's ground than the outlet the mat's plugged into, grab the red probe and step on the mat - then the volts go down, well below what they are without contacting the mat. Have you tried this?
I have a Klein tools mm300 and it doesn’t show my voltage no matter what I do
good, but then what's the point of the mat. if when you're off of it you're back to 2 volts?
Why is there NO continuity (resistance in ohms) between the two ends of the white cord?
Did u change ohms to varies ohms knob? If too low or too high the knob setting it might not register?
But I put the black one into all holes and nothing happened 100 times maybe. You say be careful, careful of what?
be careful not to electrocute yourself.
@@TerraPMats I guess it's just a theory
@@TerraPMats problem is my mat is 100% grounded, but Whenever I touch it, I feel not great. I attract all emf signals including wifi radiations. I think it's not good for my health. I think I wasted my money buying it
I would say that you should be measuring resistance not voltage. The DMM with 0.0 on the 200VAC range could be within spec since probably doesn't auto-range and the resolution of your 3.5 digit display at the 200 range is 1%, or 2 volts. Set your green/gray DMM to 200V DC and check a AA or AAA battery. Do you get a proper reading, if not set it to 20V and check again.
Imagine how many people skipped instructions on using earth only and died
Why not to make is easy by wiring yourself with a copper wire from socket ground to your ankle? Would that ground you whole body?
Thanks M8.
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.
