Clamp Meter and Electrical Test Kit

I bought this over the competition for several reasons, first... it's compact. Other line splitters have both 1x & 10X loops which make them bulky to carry around & sometimes hard to fit in tight spaces. The second reason is those double units are hard to keep in an AC outlet, they seem to fall out too easily. The third reason I bought the Klein was the name, Klein tools is a name I've trusted for many years. I've used this tool for figuring out current draw of different AC household items so I could figure out how large of a whole house generator I will need.

A great budget price point electric outlet tester. It makes perfect sense that the light output results are printed on the tester itself, my previous unit was not like this, and I ended up losing the card which showed what lights meant what. This sticker is permanent, so it will never get lost or wear off. This can also be used to test out GFCI outlets and pigtail cords. We also use this tester as an easy way to test extension cords in compliance with OSHA assured grounding rules.

A novice borrowed my original and fried the internal components, which forced a new purchase. I was pleasantly surprised that the Klein meter worked better and was easier to use than expected!

Great product gets the job done if you're not familiar with the operations of these specific tools there is a users guide to help explain the general concept of how the pill works Klein is a trusted brand Elite electrical equipment business I do like their products to specific product is excellent a little light duty but other than that for a $10 item you really can't beat it they do make similar ones for even less but I would pay a few dollars more for a trusted like Klein

This is the only way to check the GFI is working properly

Worked just like it should. Seems quite durable.

It's a great tester for gfci outlets and regular outlets

Been using this GFCI tester for a couple months now. It replaced a Gardner Bender that died after a decade in service. It is notably rounder and can be slippery to disengage from sticky outlets. However, it does the job its designed for satisfactorily. Saves lots of time troubleshooting outlets. Does fit in the smaller pocket on my tool pouch even with the ncvt and 4in1 control screwdriver.

Quality Product from Top Brand What I like about this meter is that it's simple, which makes it ultimately elegant. The quality of the tool is exactly what you would expect from Klein Tools, superior. There isn't much that you have to do with this other than turn the dial and clamp the meter on the line. The meter auto-senses the range for you, so you don't even have to worry about dialing in a ohm or amp range. Just start measuring. This does come with a case and a set of test leads as well.

This is a "must have" tool if you have a clamp meter. This is the kind of tool, that once you own a clamp meter, you wonder how you ever did without it. It makes the measurement of both current and frequency far simpler and less intrusive than splitting wires, and repairing them. I found that measurements I wanted, but was loathe to take due to the cosmetic issue of cutting the insulation and/or wires and the hassle of splitting the lines, I now frequently do because it is so easy and non-intrusive. Although the literature with the tool does not mention it, this will measure both current and frequency. Frequency can be detected on a live circuit even if the device is not drawing current as well. The 10x reading has to always be remembered when selecting the range. The 120V water cooler plugged into the device shown in the picture went OL on the 4A setting of my Klein meter, but displayed nicely on the 40A and 400A settings. Be careful on precision assumptions. The same water cooler read 1.307A on the 40A range using the line splitter and 1.26A on the 400A setting a second later. The difference is less than a 1/10th of an amp. Putting the splitter in the case of my clamp meter was possible but tight. It would be nice if the case had a little more room to make it a bit easier, but it did fit and I always put the line splitter in the case as it is often used. It's very light, and although I've had this only 3 months, it's come in very handy on many occasions. It also seems quite durable. All in all, I highly recommend this tool for anyone with a clamp meter. I can't imagine not having it.
