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. :)
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 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.
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 .
Thanks for the video first. I wonder if the other unit is a cheaper meter does not go that low on ac current. Also the larger slot normally on the left is also grounded known as neutral. They connect to the same place in your electrical panel.
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.
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.
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?
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 :(
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 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
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.
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
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 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. 😞
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
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.
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.
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)
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.
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
i'm so annoyed right now. Just bought a multimeter cause i had only an analog one from my parents. But also with the new one I can't see low voltage, the high voltage shows perfectly. Guess I will have to find a product that also works with low voltage :/
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.
I bought the Klein mm300 and I get nothing 👿 The first ohm meter I bought was a cheap one, so I thought that was the reason. Frustrating that this one doesn't work either.
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?
Worried here. I did the same test and my voltage was about 16 or 17. I touched my earthing sheet and my voltage jumped to 19-20!!!!! What is happening???? Edit: as my alarm clock was right next to the grounding socket, I move to the socket on the other side of the room. Same thing, slightly lower numbers. Body voltage touching the earthing plug and my fingers was about 13-15. Touching earthing plug and fingers on earthing sheet and it went to 15.5. Does that mean dirty electricity in my flat? Which would mean I need a rod even though I am on the 2nd floor (UK)? That’s going to be interesting to install every day…

So in another video the guy says to use the 200m on the V with no squiggly line side for this kind of test.. And thats the only one that works with my multimeter. If i try to use 200 V~, i get all 0's just like yours. But, if you switch it to the other setting it then works.
Hallo Volker, kann man die Spannung auch ohne Steckdose messen? Hab mein Bett im Wohnwagen mit Aluklebeband beklebt und mit Kupferkabel und Aligatorklip an einem draußen in den Boden gesteckten und verzinkten Zelthering verbunden. Spannbettlaken ist darüber. Keine Ahnung, wie ich checken kann, ob es funktioniert😅
Thank you. I guess mine doesn't work. I just tested it and I can't get a reading at all. I'll have to take it back for a refund and look for another one.
@@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
@@Tom-uk1vf Yes, obviously. So I went out and bought a new one, that supposedly measured low voltages, and it too did not actually measure low voltages. I’ve bought two multimeters, and neither of them do that. So my question is, is there any specification that I should be looking for?
@@EnjoyerofTH-cam I was having the same problem with my cheap multimeter I bought, it says it ranges from 0 - 200/300V put doesn't work. Idk if there is any specification but I recon buying his multimeter is the easy way to go. He's using the MM325 but I can't find it here in europe so I'm buying the MM300. (Klein tools) Hopefully it works.

So in another video the guy says to use the 200m on the V with no squiggly line side for this kind of test.. And thats the only one that works with my multimeter. If i try to use 200 V~, i get all 0's just like yours. But, if you switch it to the other setting it then works.
Would you please share the link to that other video?
Dude you save and I test with another one and same thing
AC ist logic to me! It must be DC so you will see a declining voltage.
Hallo Volker, kann man die Spannung auch ohne Steckdose messen?
Hab mein Bett im Wohnwagen mit Aluklebeband beklebt und mit Kupferkabel und Aligatorklip an einem draußen in den Boden gesteckten und verzinkten Zelthering verbunden. Spannbettlaken ist darüber. Keine Ahnung, wie ich checken kann, ob es funktioniert😅

Ein Ende des Meßkabels zw. Daumen und Zeigefinger und das andere Ende an den geerdeten Draht.
Thank you. I guess mine doesn't work. I just tested it and I can't get a reading at all. I'll have to take it back for a refund and look for another one.
Mine goes up when I touch my hand to the mat...
Because not all multimeters are continuity testers
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
The mat was already connected to the same ground. The test makes no sense.
Second multimeter problem why not showing reading
don't know.
Thats how you die 😂🐒🙉
You showed us a problem with the second multimeter, but not how to avoid it…not very helpful.
The problem is the multimeter doesn't pick up on low voltages, that's not fixable... that's why he said to buy a new one.
@@Tom-uk1vf Yes, obviously. So I went out and bought a new one, that supposedly measured low voltages, and it too did not actually measure low voltages. I’ve bought two multimeters, and neither of them do that. So my question is, is there any specification that I should be looking for?
@@EnjoyerofTH-cam I was having the same problem with my cheap multimeter I bought, it says it ranges from 0 - 200/300V put doesn't work. Idk if there is any specification but I recon buying his multimeter is the easy way to go. He's using the MM325 but I can't find it here in europe so I'm buying the MM300. (Klein tools) Hopefully it works.
@@Tom-uk1vf Thanks for your help!
Did the MM300 work
