the mat/wire connecting to the mat has a resistor. loads, like resistors and appliances "break" continuity that's why it would be "open" because current applied doesn't flow to the other end of the circuit.
I think you forgot to show the step where you plugged the white chord into the ground slot on the wall before testing. Also, the white wire should still show continuity. You may have to insert one of the prongs into the center of the snap end.
I got a grounding sheets from a different company. I tested the grounding wire for continuity and it had continuity and acted like any wire would. Then I tested volts with a cheap tester and showed nothing. Then I used a much higher quality tester and when I put the ground wire into the ground on the wall it showed a little voltage even though the red wasn't attached. I am wondering if the voltage clamp caused a little bypass? Anyways when I grabbed the red wire the voltage went up a couple volts. When I sat on the bed it went to 0. So it is definitely grounding. Whether it will do anything positive is a different story but here's hoping...lol
The resistance of the cord is higher than the continuity threshold of the multi-meter. It will show OL (open line) and still however, be conductive. This can be explained in more detail online if you do the research.
You should have continuity between end connectors of the white wire. No reason to have a resistor between that line and ground. And you offered no explanation as to why there was no continuity. It is possible to have a functioning mat and a defective white connector. Testing the continuity of the white wire would be on the list of troubleshooting ideas. If it isn’t working: 1. Grounding plug on wall outlet may not be connecting to ground (sometimes they’re not). 2. White connection wire may be defective (do a continuity test). 3. Mat may be defective if 1 and 2 test ok.
can anyone tell me why when i do this in England to test my sheet , i cant even get a reading from testing the current level going through myself with the black pin inserted in the earth slot and then holding the red one .. its either at zero constantly or sometimes it say 0.1 .. ive tried differnt mains plugs all over the house and even gone outside and put the black pin in the ground and touch the red pin , nothing!! brand new multimeter , tried my dads multimeter , new battery's etc .. whats going on ? aside from that ive actually purchased a ground rod and 40 foot cable off amazon , cable straight from the earth into my bedroom and ive got a 4mm copper rod the width of my bed layed at the bottom touching my legs .taped in place with duck tape ... i think thats gotta be the best way of doing it , its comfortable and im always in contact with the copper .. i dont think going into the mains is good if the earth is not good .. my house is 70 years old how do i know the grounding rod has even been replaced in that time
@@Carydbster if you hold your phone thats charging with one hand or touch a tv or monitor you should get a reading of 2/3 volts then you can sit on your sheet and it should go down to zero ... im still skeptical about how effective grounding is but at least i know my sheets working
Continuity is required for the device to work. My guess is that you only touched the outer metal piece on the female side and not the electrical contact.
The resistance of the wire is higher than the multi-meter`s continuity threshold, therefore it will not register continuity and show OL (open line). The cord however conduct as it was designed to. For those of you who may think there is no wire between the two connecting ends...I have already tested that theory...without foolishly cutting into the wire. I am a metal detectorist and I have several sensitive machines that do register a faint low conductive metal when the cords are passed by their coils.
I agree, why doesn't the wire have continuity? You can't say the logic is flawed if you don't explain the science behind why.
Okay thank you for showing us how to test with this tool

What kind of mulitimeter is? I know the brand is Klein, but which one do I buy? thanks
It looks like on the video, that he is using the Klein MM325 Digital Multimeter. It is kind hard to see though.
I think you forgot to show the step where you plugged the white chord into the ground slot on the wall before testing. Also, the white wire should still show continuity. You may have to insert one of the prongs into the center of the snap end.
I agree. The prong needs to be inserted deep into the circle of snap

interesting! thanks for the clear video. why wouldn't the chord show continuity?
I think that there is a small resistor in the cord to prevent accidents from the outlet,
The resistance of the cord is higher than the continuity threshold of the multi-meter. It will show OL (open line) and still however, be conductive. This can be explained in more detail online if you do the research.

If it isn’t working:
1. Grounding plug on wall outlet may not be connecting to ground (sometimes they’re not).

Same here. I do not register on the mm. 🤔

If there is no continuity on the cord, I can't see how this works. I am a licensed electrician, please explain this.
I believe it has a large resistor
The resistance of the cord is higher than the continuity threshold of the multi-meter. It will show OL and yet still be conductive. GOOGLE it.
There is a 10K ohm resistor in line to prevent AC induced voltages.
