Rated 5 out of 5 by from Design Consistency I purchased my Fluke 177 DMM over ten years ago and it still functions properly. I just purchased this new one for my sister, and it looks and functions exactly the same. Its nice to see that Fluke has avoided the cosmetic re-design fetish that plagues so many other manufacturers -- now I won't need to learn how to use the new DMM before I teach her how to use it.

Rated 5 out of 5 by from Great as always This is my second Fluke and just like my first one it’s great. Only reason I bought this one was because my other Fluke screen is getting hard to read now that’s it’s 15 plus years old other than that it still works great as a backup.

Rated 3 out of 5 by from A good meter I've used this everyday for 1-1/2 years and it definitely gets the job done for commercial electrical / fire alarm installations. I got it calibrated at 12 months to keep it accurate. The only features I wish it would have are 10,000 counts instead of 6,000 counts, Low-Z (stray voltage adaptor is a hassle), especially since more electronics are being incorporated into the industry.Other than my wants it's a very reliable meter to use and have.

Rated 5 out of 5 by from Portable and Functional I purchased 2 Fluke 177's for our shop at work. They are light weight, portable, and accurate. They are rugged enough to stand up to the demands of our heavy industrial facility. It is nice to see a high quality product with a quality warranty still available in a world of disposable tools.

Rated 5 out of 5 by from Can't do with out it This is the first meter I go to when I am diagnosing an electrical problem, Wether it is testing a fuse, measuring current (AC DC) or checking miliamps this meter has it all, And durable! Have dropped it a few times with no damage

Rated 5 out of 5 by from Especially useful is the "hz" function This is a DVM that I use at work (quite a bit). Besides the typical uses for it (DC voltage and Current), I also work on developing blower and the "hz" function is extremely useful for monitoring the tachometer output (square wave function, freq corresponds to blower rpm)

Rated 5 out of 5 by from Engineer's Dream I bought the 177 about 1.5 years ago at the beginning of my sophomore year in an electrical engineering program, let me tell you, this thing has never missed a beat and is always on the money. I would absolutely recommend this to anyone looking for a quality meter. The only thing I would change is to add a temperature setting but that is addressed in the 179, it wasn’t a feature I thought I needed but I would definitely get it now given my previous projects. Overall, great meter, you won’t regret buying, but I would pick up the 179 for some added functionality.

Rated 5 out of 5 by from Does the Job! This multimeter is robust and does the job! Its ease of use and big display make it a breeze to use. We have about 6 of these at our facility. Hasn't died on us yet.
