With so many types of test equipment available for the electrician, its hard to keep track of what is out there. In this episode of Electrician U, Dustin talks about some of the testing devices that one of our sponsors, Klein Tools, has available.

First up is a simple voltage tester. No frills, but definitely worth thinking about. All it tells you is if there is voltage present. But that is the beauty of it! Less to break, less to malfunction! Small and compact, it easily fits in your pocket or tool pouch and its price is also super affordable. In addition, it does test on a range of voltages not just 120.
Klein’s ET-310 is next on our list of testers. This tool allows you to plug one end into a receptacle and with the other end (wand) you can go to the panel and scan the breakers until it audibly lets you know which one you are plugged into on the other end! Super handy and keeps you from running back and forth between panel and receptacles until you find out which one you are working on!!
Also available from Klein is a thermal imager. Unlike a standard laser type thermometer, this device also has a screen which allows you to SEE an infrared picture of what you are testing, not just get the digital readout of the temperature. This can be very useful in identifying hot spots in a circuit where there is a potential problem point or a loose joint/connection, without having to disassemble each and every device/bolt in the arrangement.
Klein’s Amp Clamp type meter is next up. This tool will typically tend to have Less testing options than a Digital Multi Meter, but More than a standard voltage only tester. In addition, it has a split clamp on one end that you can clamp around a wire to see just how many amps are flowing through the circuit you are testing. They are available in different voltage and amperage ranges to suit the need of the electrician. If you are going to have one type of meter in your arsenal, make sure it is this type! They are totally invaluable!
A borescope is the next test instrument we look at. While not something that you would use every day, it is surely nice to have to allow you to look into an opening and behind something that you normally couldn’t see into. So, say for instance you wanted to see if there was an obstruction inside the wall cavity you just cut a box into, you could simply insert the camera end of the borescope into the hole and look around! Nice!!
A Megger is a tool that the average electrician probably Doesn’t have in their personal tool kit, but one that most of us have used them. These typically look much like a multi meter, but what they do is send a high voltage signal into the conductor they are clamped onto and can sense if that current is leaking out somewhere and escaping indicating a potential problem point within the conductor. A definite must use tool for the electrician.
The last tool we are looking into is a Earth Resistance Tester. This particular meter is a three-point fall of potential type, though there are four-point fall of potential types available. This tool allows you to test the immediate earth surrounding the area you are working in to see how much resistance the earth carries. An invaluable tool for service installations/problematic grounding testing.
We hope this has been helpful in showing you what types of electrical testers are out there that you can easily access and which ones to select. Continue to follow Dustin and Electrician U as we are constantly adding new content to the platform

Need a biddle meter to show

joetapout says:

The klein circuit locater is awesome . I used it at church to find the breaker for septic pump. It worked thru a metal building and about 100 yards

Osman Espinoza says:

God bless, peace and love to be upon everyone in the name of The Messiah Jesus Christ (Yahshua).

Klein should invent a tool that detects a light switch circuit breaker.

SlackersIndustry says:

great vid except i doubt electricians have more tools than mechanics 🤣

Mr cool Lu says:

Very informative thank you very much

Mario Martinez says:

I disagree HVAC/R techs have the most tools guaranteed, i have all the tools you displayed and more

Pellervo Kaskinen says:

I am not a professional electrician. I have earned my living by designing electronic controls. But for my home use I have pretty much the whole set of various meters listed. The two items I am missing are a borescope and a ground resistance meter. Actually I could use some of my bench meters to make the ground resistance measurement. The borescope has been on my wish list for a while, but so far I have not found one that would meet my specifications. Otherwise, most of my meters are from Fluke, HP, TEK and Keithley. And something I would add to preferred instruments list for certain electricians is an Ethernet cable termination tester. On the other hand, my personal collection also contains a WiFi scanner attachment for my iPad Mini. And last, but not least, a 2-channel oscilloscope attachment also for the iPad. However, there is a popular saying that you never have enough of some goodies, and measuring instruments for sure belong into that category!

Bob Billybob says:

A fluke multimeter will do pretty much everything in this video.

George Dvojacki says:

Love your videos, Thank you so much for putting them out there. Except I have to disagree with you I think HVAC technicians have more tools.😁🤣🤣

Hosain Parchment says:

Can u do a review on the Klein 360 laser level?

Beau Woodbury says:

Went on a service call by myself for the very first time last week I wish I would of had a circuit tracer with me. The panels were not labeled and it was a business so I didn’t want to just start shutting stuff off. I was forced to work live to get it done. I just got one and I will never ever not have it with me again

Scott Rothe says:

Hey Dustin
Thanks for all your very informative videos. I had a question concerning changing over from 3 wire to 4 wire on a stove or dryer. Why can't you run a seperate neutral wire to use as the 4th wire instead of having to pull all new 4 conductor cable! Is article 300.20 the reason why you can't, or are there other reasons also? I am interested in what you have to say, code specific, about this topic!! Thank you for your response.

K D says:

i am a home owner who got frustrated that the panel was not labeled correctly. The Tester is great and it cost me less than what an electrician was going to charge to do it for me.

Electricians Do not carry the most tools, HVAC guy's carry way more stuff… I do HVAC, diagnostics, sheet metal, electrical, plumbing, framing & more
Electricians do electricity, HVAC guys do it all..

Kimo Williams says:

We're still waiting on part 2!!! Can't wait for it to come out @electrician u

Mark says:

Really interesting. I see others have already stated that Megger is still a brand for test equipment and sorry if I have missed it in the comments but a "megger" is used as shorthand for an insulation resistance test in the UK, probably because Megger was the prominent brand that made that type of instrument. Out of interest do you not use Multi Function Testers (MFT) in the US? They are the most common type used in the UK for testing new electrical installations and for periodic inspections both domestic, commercial and industrial. The MFT normally encompasses Continuity (Low ohm), Insulation Resistance, Loop impedance, RCD Testing (time and ramp tests) and RE testing for earth rods and electrodes (where not provided by the electrical supply company), voltage and phase rotation. As part of our UK electrical code BS7671 IEE Wiring Regulations we have to carry out a whole bunch of tests as part of commission an installation and regular periodic testing and inspection that utilises most of MFTs functions, what do you have to do in the US in the way of testing and regular inspection? If you have covered this before I am sorry I missed it.

Daniel Weidig says:

What do you think is a good fault finder? A device that gives you length to fault. They are pretty handy in heat up, the only problem I find with them is if you didnt wire the house then you have to make good guess where the fault might be to minimize cutting into drywall to find it. They are expensive and are becoming more difficult to find.

Tommy305 says:

What's the best manufacturer? I see you use all Klein… or are sponsored by them. I use all Kaiweets and I know alot of electricians use Fluke. Honestly I didn't buy Fluke because they had all bright neon colors which looks like Tanca Toy colors.. KAIWEETS and Klein use black and subtle colors and have nice big screens. Kaiweets is sold all over Amazon and is the most popular on there. So anyone NOT sponsored here want to say their opinion on those brands? I get different readings on my clamp meter depending which direction the wire goes in my clamp, not sure if that is normal or not so was wondering how accurate these 3 top brands are.
