I operate a rural water district and have three-phase motors to monitor and troubleshoot, but it works great at home as well. I bought this meter first for its size. It fits well in my pocket or the palm of my hand and is surprisingly light in weight. It will fit in tight spots where I don't like using a larger sized clamp meter. It gives fast amperage readings and is accurate as compared to readings taken on the same motor at the same time with an electrician's Fluke. Reads AC amps to 600A Max. Does not read DC amps but I have another meter for that and capacitance. AC True RMS and DC volts to 600V. It checks frequency on current or voltage signal, resistances from 40 Ohms to 40.0 Meg Ohms, tests diodes and continuity with a mild chirp. The CM-450 is the only meter I need to carry with me to take readings on pumps and motors on a regular basis. I use it for troubleshooting. I reach for it first because of its slender shape. I fasten the Red probe to the body of the meter with a latex medical tourniquet (the kind they throw away at the doctor's office) and put an alligator clip on the black lead. I use it with one hand to test voltages and stick the other hand in my pocket for safety. I take resistance measurements the same way, when I can. You can hold it in your hand and be able change functions with your thumb. They used to be cheaper but their demand is up and so is the price. If you can find a better meter for the same money buy it. This is the best meter I own for the price. I intend to get another as a backup. I don't want to be without one.

Offers more instant information than fluke amp clamps. Delta and Hz buttons great for 3 phase work. Hold button good for short memory and hard to get to spots. Do not hesitate to buy!

The Greenlee clamp on meter is very good and a great addition to my tool kit. For years I have use a Wiggenton voltage tester from Square D but the insulation on the leads finall cracked. The Greenlee is a big step up and I've already used it to check amperage on several appliances.

I bought this meter after borrowing my friends Fluke. I searched for a good price on Fluke and decided that is one would probably work for checking my irrigation pump setup. I was very impressed with it's operation. This one has True RMS whereas the Fluke that I borrowed didn't. I didn't notice a difference with my setup but for this feature gave me security. This unit is well built and in some aspects, better than the Fluke counterpart. I highly recommend this product from Greenlee.

I bought one from home depot for $150 for a different brand though. and returned it since this one though looks a bit slim but it does the same job. I use it to measure AC current usage for my new installed Mitsubishi ductless split systems to calculate the power comsumption of the units. it works great. very great price ($29.99). Amazon satated it will ship about two weeks later once I ordered. Actually I got very fast, within 4 days.

This is a good value for the general user. It does what was advertised and that is all I needed without spending alot of money. I do wish it had a lower amp scale in the range of 0-40 amps.
I do recommend to others.
