You are so right about this claim noncontact voltage tester. I have one in each of my tool bags. I have given them to my nephews when they do electrical work in their own homes. I want to keep them safe. This device is so necessary if you’re doing any electrical work at all.

The video explains very well. The voltage test pen is still necessary. I bought a renhotecic brand test pen not long ago. The test is very convenient, accurate and safe. Family must.

Thanks a bunch! I have to replace or... Troubleshoot a disposal. Before I do anything I wanted to make sure it was getting power. Like your light bulb example! I appreciate you!

Great video and thanks for sharing. Would this pen work to check for a live wire with higher voltage (240) on something like a hot water heater?

Is there a beep feature on your model? I have the NCVT-1.. It beeps pretty loud repeatedly along with the red light flashing but sometimes only one beep but most of the time continuously and it doesn't stop until you pull away.. Which by the way your link seems to be upgraded from your NCVT-2 to the NCVT-3 Also mine does not have any selection for different voltage but it does say on the side sensitivity ranch 50-1000 V also mine only has a power button which can unfortunately be very easily bumped! And I think I remember receiving a notice from Amazon that my model was recalled lol

There are clones out there going for cheap and can make sound and show graphs. I bought one. Definitely a handy tool. Before I was scare of dealing with switches, breakers, and outlets. This sure is a safety measure.

i put the tester up about a meter next to my wall and it started beeping hard. what could be in my walls that extend the range by a couple feet?

Nice explanation & demonstration, thanks!

This was helpful, thank you.

Such a clear and concise helpful video. Thanks!!

Great video. I’m sure I’m correct on this, but for future videos on this product, consider clarifying what the colors indicate.

What do the different colors mean??? There are different lights from different breakers. Doesn't matter if it I turn off the main fuse or not

Thanks so much. I will be checking this one out!

Thanks for the upload !

I have this tool. Can't figure out why it can go from green on the right to blue on the left.

I like the one that also has a plug in on the othet side that tells you if its wired correctly.

This came with my new Dewalt multimeter and I didn’t know what to do with it. I thought it was very cool going around the kitchen touching it to the Keurig wire, the air fryer, etc. But then I touched it to a mixer that was not plugged in and it gave me a positive reading. What’s up with that?

These are nice for tracing wires and checking outlets but if you can check voltage with a meter always do that first.

Very helpful. Thanks

What about for mechanical use ? Relays all that good stuff

Thank you

Very helpful.

What is suggest tester for so much wires in a large box if test single wire has power with insulation with so much wire cross each other

Very helpful

Very good information. Tks

Never at work with out it but I have found the one with the flashligt to be very handy. Soon after you start carrying it around it power cycles and beeps in your pocket. I think the battery spring just needs to be more robust. Sometimes a small washer helps for a while.

Can test car fuses

Great share, brother!

could this be used to detect if there's a wire in the wall? (so you don't drill a hole there?)

how to order

Why is the water proof one cheaper

How do I know when to use 12-1000 or 70-1000?

I came to try understand meaning of different sounds and different flashes since there is no English description. But you don't have it too. Yes and it is 1 year ago. Everything is changing so fast.

Fun bonus, it will also detect if an ionizer found on many air purifiers is actually running.

Will a detector like this register voltage from a dryer outlet?

Thanks for the review. It was very useful. Just to add the one I brought has a vibrate function as well.

This tester does not tell you if you have power in the outlet or a switch. It tells you there's voltage on the line,but you can have perfectly good reading ,indicating good line and the outlet does not power anything. Easy test proves the pen is not a tool to detect power in the wire- rub the tip of the pen against any plastic bag. It will glow red and chirp( if the function is present). Needless to say , the wattage shown is minuscule.If the live wire got shorted under the screw in an outlet and there is an oxide/carbon build-up on the wire,the pen will show you a perfectly good outlet,which cannot power anything.But keeping in mind all the limitations, a useful gadget

Show a demo with the light bulb!!!!!

can i see the circuit of this device? i am making a project and i am going to do the same of this device. Can you open it up and send me your photo? Unfortunately I can't find it google.

Can you use this on a water heater?

Can you use it testing car fuse box

Can this pick up possible voltage that may have leaked into water i.e. swimming pool etc..?

Will this tester work with an electric fence? The ground side is the ground right?

Can this tool be used to check Christmas lights when bulbs are burned out? Very nice video.

4:22 That’s the most useful test of all. In a minute I’m driving over to Harbor Freight to get their 5$ NCVT and see if it’s worth a crap.

First time on your channel. Very confused ... You aren't wearing any flannel!

Do not sleep on these. Just turned the power off to what I thought was the entire room I was working in and like the rookie I am, I got a nasty shock. Don't take any chances with wall power.

Not all install positive side down. Mine installed negative side down.

Can a voltage tester detect a break in a wire?

What does it mean if my fingertips makes it turn red?

kzfaq.info/get/bejne/nZ14iqWXysfbemg.html yours appears to be silent and the red light is not flashing looks like the NCVT-2? I wish you would've put the model number since there are several of these this link explains all the different models of Klein voltage testers.. i'm going to get the NCVT4 with thermometer.. BTW in this video the NCVT -2 does beep.. Is there a way to turn off the beeping?

These are banned in the UK in most industrial settings as they do not work on some cables such as SWA and the only approved method for testing for dead is prove the tester, test all power sources including earth and neutral. Then prove the tester again. This is standard in the UK but non contact testers and volt test screwdrivers are banned for safety reasons

Why don’t I hear any beeping sound?

W

You didn't test the light bulb for us.

*I am buying one for Ghost Hunting to see what happens.*

Take the batteries out when not using, if the batteries leak they will swell and you can't get them out and your tester will be ruined.

More like camera “operator” failure, … lmbo!!!

Mine is not green it's red

This tool shows you how much electrical radiation you are exposed to every day!😮

So green is good and red is bad

We don't need the first 47 seconds

Where's your flannel, so disappointed

Too much talking and not a lot off teaching.

This will accurately detect a live wire?

Here is he tester on Amazon amzn.to/3EkdLTg

🥱
