Rated 5 out of 5 by from Great multimeter! Fluke 117 is a very precise and reliable multimeter. Back-lit large display is easy to read even in dark test areas and the analog bar graph adds accuracy when monitoring measurement changes. VoltAlert - a non-contact voltage detection feature is very helpful. Ergonomic design allows for one handed operation. A must have for every electrician or home owner. Also, great for school labs.

Rated 5 out of 5 by from My Go To meter! I purchased this meter several months ago and it's great. I really like the capabilities of the instrument especially with the size, weight and feel in your hand. I also have a Fluke 87V Electricians Kit for additional capabilities or when a second is meter needed. But the 177 goes with me into a site and is the first reached for everyday use around my shop. I've been using Fluke instruments since first working in a laboratory 1975. I also have an(cient) old Fluke 8012A Lo Ohm capable DMM on the bench in my garage at home. About 40 years old and the battery is long gone but still working on AC for quick bench measurements.

Rated 5 out of 5 by from Durable and accurate meter I purchased this Fluke 177 for my personal use due to working with Fluke meters in my workplace. I am an electrician and I work in electrical maintenance and I know how well made a Fluke meter is. My meter is used for many things ranging from troubleshooting basic electronics, house wiring, lighting, and working on RVs. I am very pleased with it. I always try to be careful with my instruments but it is good to know this Fluke is designed for the work environment. I would recommend without hesitation.

Rated 5 out of 5 by from Excellent product. Now complaints, no downsides Fluke 177 purchased for light industrial work. It is solid, stable on the standup bass, and reads easily. No downside to this intrument as long as you don't need temperature. If that's the case get the 179.
