As an electrician I own a several different non-contact voltage testers and they are handy. To the DIY take notice that he checked the circuit hot before he checked it dead that way he knew his tester was working properly. Very nice review and video!

KZfaq is the best thing on the internet you learn n learn thank KZfaq

For a newbie like me, your video was clearly explained, demonstrated and informative at just at the right pace. My model NCVT-1P was $19.97 at Home Depot. i got lucky in picking the right non contact tester and feel ready to change out my light switch!

Thanks for explaining how "Klein Tools Non Contact Voltage Tester" functions, in a very clear manner.

Hi, thank you so much for the easy to understand video. I am a single mom and have to fix all that I can myself. I purchased one of these voltage testers and really was not sure of its capacity, but you explained everything about using it so well in this video. I now feel comfortable using this tool to check for voltage without having to consult any guy to have to check it for me. Thank you again!

I just got one of these in a set with my multimeter. Wasn’t exactly sure what it was for or how to use it. This video answered all my questions.

this is the way that you should explain a simple but potentially dangerous tool, slowly deliberately and repeatedly and in great detail. when needed.thank you very much.

Best explanation yet.Simple and to the point.

Ah.....you just calmed me down. THANK YOU!!! I'm actually afraid of electricity but I have to change out a gfci outlet that keeps tripping. The instructions in the package were very tiny and not totally clear. There was no mention of putting the tip INSIDE the outlet even though it looks like that's what you would do. Your video cleared everything up and ALSO taught me how to test a cord!!!

I'm New to the wave world. Your instruction is straight forward, clear, especially helpful, encompassing safety. Thank you

I'm not an electrician but I recently bought this to help with replacing a light switch. It's very handy and works great.

I just bought this tester a couple of weeks ago to install an exhaust fan for the bathroom. The electrician left 3 switches, one for the light over the sink, one for the light in the middle of the bathroom, and a third for a future fan installation. That made it easy for me, but I needed to test it to make sure the power was working before and after it was turned off from the breaker and this tester worked liked a charm!

I’m a total dunce around electrical, I can wire a guitar, but I don’t understand the fundamentals. Thank you for the helpful video and showing me how to use this tool to prevent unwanted zaps!

Yay! Thank you, thank you, thank you. I've had one of these kicking around the tool box for a long time and never knew how to use it. Now I do! Great video.

Thank you so much for full details about this product...you explained several things that I did not know...now I can use my Klein Tools voltage tester with confidence!

Very straightforward and simply said. Fantastic video thank you very much. You are a great instructor.

most thorough, clear and helpful tutorial on this tool. Thank you.

for a electrician like me this things are pure gold!!!

Great video. Thank you for taking the time to make it. Very educational for begginner DIYers.

thank you! getting the little woman to unwire the disposal proved difficult with two nearby plugs functioning after the breakers were flipped to off. found a separate box on the back of the house.

Very helpful tutorial with clarity & conciseness! Thank you.

I came across my Klein the other day..needed a quick review and found your site on KZfaq. Thanks. Great video and YES I did subscribe.

Well done. Simple straight forward. Thanks Jim

Excellent, bought one of these but the instructions were not very clear. I feel confident using it now after your video.

Very thorough thank you so much I was using list for my car but it wasn’t working how you was working it and you pointed out that the car has DC current and this is not going to detect DC only AC thank you so much

Boom... this helped me find a bad outlet which I was able to test... never knew how to use the NCVT until now.

Works great. Very sensitive, picks up electrical fields.

Great comprehensive advice. Thank you!

I was ready to return this as the instructions included are vague for actually using it. Great instructions for turning on/off/silent but you have better instructions. I'm keeping it now. Thanks.

Awesome detailed video, thanks for sharing!

Tool very well described by you. Do you have a video re the 300m? Thanks

Bought one doesn't beep finally heard it has a silent mode I will try this thanks.

Can this detect continuity for things like a thermal fuse? I've seen multimeters normally being used for this.

thorough review thanks

Sure enough it work.. thanks

Great concise explanation, thanks!

CRE 2018. Thanks for the explanation i have this tester and it would stay green on wire i know to be !!hot!! i figured it was malfunctioning or bad batteries. now i see why

I have a circline fluorescent light fixture that's not working even though I installed a new bulb. The fixture has been there a long time but up to this point I have never had an issue with it. I don't know if the problem is the switch or maybe the ballast. Would one of these testers be helpful? Thanks.

Thank you very much, it is very helpfull

Awesome video… super helpful

This was a very helpful video thanks new subscriber

Awesome! Thank you for this video!

Very good review. thank you

many thanks for a very helpful video

Very thorough video

thanks for the explanation

Just picked this up after watching your review. (Power went out in one room of my house yet no breaker tripped.) used this to check the outlets. All show green (no juice) except one. One outlet both sides (neutral and hot side) show red. Any idea what that means?

Excellent video.

muy bien explicado , gracias.

Great job!

Thank you so much, very detailed! 👍

Love this tool.

This was a good review, two subjects I’d like your opinion on. First it would have been more to the point to video you testing the tool with a outlet you knew to be live before testing the suspicious outlet. You tested the tool on the switch and had it been bad it would have left the impression that the cuicuit was not energized. Secondly, I disagree with your comment that the Kline NCVT-1 is not for professional use, in my opinion, anything Kline manufactures is suitable for a professional and can be trusted. Other then that in my opinion, this was a good review

Great review for someone who doesn't know anything about working with electricity. Strong work.

Thanks that was the perfect intro.

Very informative. Thank you.

Thanks so much!!

Thanks Danny

Very helpful, thank you!

Nice video man I appreciate it

Clear and simple explanation. Thanks

Mine is too sensitive.., as soon as it's anywhere close to any live wire (say 6" radius) it starts beeping red. I wanted to check the wires inside the dimmer switch in the wall. I took the cover off and then unscrewed the switch and pulled it out of the box... I wanted to know which one was the LOAD and which one was the HOT wire but even though I pulled the wires as far apart as possible, as soon as I approached the area with my tester, the red lights came on! So frustrating... What's the solution? One thing though, should I have detached all the wires from the switch first to get a better result? I did mine while the switch was still attached....

Hi thanks, I got a weird problem. When I test an outlet, (it's an old house, 2 wire, no ground) Both live and neutral turn red. However, when I measure between the L and N with a volt meter, there is 0 voltage. The outlet is dead, no lamp turns on. So I ran a wire from the N at the outlet back to the power box to test for continuity break is the Neutral, and I get a voltage of 117V between the N wire coming from inside the house and the Nueutral connector bar at the panel? What is happening here? Thanks.

nice review. Thanks!

شكراً Thank you
