Rated 5 out of 5 by from Might as well have the best I have been using this meter for a full year now in a small cabinet shop. I routinely locate blown run and start capacitors with this meter it works flawlessly. I could not ask for more, easy to use and top quality.

Rated 5 out of 5 by from I should have bought one years ago! After decades of analog, then non-auto ranging meters, I bought a Fluke 115 to see if the hype was legitimate. The brand was something I noticed when working in two different careers, both where I had frequent contact with HVAC and mechanical engineers who recommended, without hesitation, the Fluke product. Extensive research informed me something like an 87V would be terribly unnecessary for my use, but something like a 115 was ideal. Aside from the basic homeowner/DIY uses like determining continuity or checking vehicle batteries, I was able to use the 115 for my new career as a music teacher where, to save money, I’m constantly repairing instruments, which include several electronic items ranging from speakers and amplifiers to samplers and drum machines. Ensuring solid connections and proper voltage would not only be much slower with a set-range, or worse, analog meter, but I wouldn’t be able to use functions like the min/max button to check battery life or maintain safe voltage levels. I’m also able to gauge Ohms so speaker capacity isn’t overwhelmed by amplifier output. The backlight is great for working in a dark driveway/parking lot or in tight spaces created by rack mounted electronics. I also appreciate having a fuse, unlike the cheaper meters, which would just fry and you’d have to replace. Having buttons large enough and with ample separation is helpful when you’re working with gloves on or sometimes need to press one without looking; the tactile function is a great benefit. Lastly, the overload prevention feature where the meter indicates you’re on the wrong setting is invaluable towards saving the meter and the fuse. Overall; an outstanding meter!

Rated 5 out of 5 by from Love This Meter!!! I purchased this meter a few months ago and absolutely love it! It has all the features I need plus a heavy duty build. Couldn't have asked for a better meter!!! I would recommend this for anyone who does a variety of electrical testing.

Rated 5 out of 5 by from Everything you would want from a basic multimeter If you need a solid meter to handle all basic functions, the 115 is perfect. I use it for testing and troubleshooting power supplies, A/V equipment, testing batteries and chargers, and basic electronics repair. The battery life is fantastic and I can always trust the readings are accurate. User interface is simple as it gets and autoranging switches quickly to the correct range allowing you to focus on the measurement. Continuity beeper is fast to react which is good when tracking intermittent faults in cables. Backlit display is nice and clear and great when working behind a dark equipment rack. Fluke isn't the cheapest option out there, but once you've used one of these you'll never want to go back to a cheap meter again. My only complaint is the test leads would have been a lot nicer if they used real silicone wire. They're stiff and a bit lumpy from packaging and haven't straightened out fully. I won't take off a star though because this is the case with most meters on the market.

Rated 5 out of 5 by from Great all-around multimeter Fluke continues to be the standard and this unit is no exception. Having the frequency and capacitance in addition to all the other normal features is great. Good for HVAC troubleshooting and most all basic AC and DC work.

Rated 5 out of 5 by from Simple and accurate! This meter has been accurate, durable, and problem free for the two years I've been using it. I'm using this meter to debug problems with electronics, so I didn't want to double my workload by having to constantly fight a sub-standard multimeter. Everyone I work with uses Fluke multimeters, so it was a really a no-brainer.

Rated 5 out of 5 by from Great Starter DMM I have had my 115 for a year and love it. It just feels right in your hands and the performance is pure fluke - quality. It is so much better than the "budget" DMM I had used previously. It is always spot on and very easy to operate, even one handed. I am new in the electronics field and my 115 has assisted me reliably in the learning process. If you are just starting out or want to upgrade to a better device, I highly recommend the Fluke 115.

Rated 5 out of 5 by from Simply the best From the late 80's until the early 2000's I worked in the automotive industry. The last 8 of those years I specialized as a drivebility and electrical technician. The first multi-meter I owned was a Fluke (I don't remember the model at this point) that was very basic. As I advanced in driveability and electrical diagnosis I felt I needed a meter that had more functions so I traded the Fluke in on a meter from one of the tool dealers because of "functions per dollar". That meter started out ok but as time went on I realized that it wasn't such a great purchase, dissatisfied in it to say the least. I currently work as a fleet maintenance supervisor/operator for a company that specializes in product sales and contract services for the golf and turf industry. With that position I needed a reliable meter that was also easy to teach others how to use. I chose the Fluke 115 for that purpose. Simply the best.

Rated 5 out of 5 by from Great meter at a reasonable price I use Fluke multimeters both at work and at home, to trouble shoot equipment and household electrical issues. The 115 is a particular favorite, because it has all the features that one would normally need (AD and DC voltages, resistance/continuity, DC amperage). The meter is well made, the dial intuitive, and the display large and uncluttered.

Rated 5 out of 5 by from Fantastic and Accurate Meter I wish I bought this meter years ago. I have used several no-name brand handheld meters, Radio Shack, etc, and this is hands-down, the best, and worth the extra money. It's super accurate, the batteries last, the look and feel is top-notch, and it's feature-packed. I love the back-lit display! I have a few Fluke bench meters as well, and I'm happy that this handheld holds its own against these workhorses.

Rated 5 out of 5 by from Performs exactly as advertised! I got Fluke 115 multimeter as a birthday present. I am an engineering student and use this multimeter on a regular basis testing of my own projects. In fact, it has better accuracy in measuring than university lab bench multimeter. It is durable and I highly recommend to students and DIYers as a primary testing multimeter.

Rated 5 out of 5 by from Great value! I use this meter in the entertainment industry for both low voltage DC applications and High votage AC applications. It always does its intended job and handles the rigors of multiple users and abuse and keeps on ticking. I would not hesitate to buy another one of these when the need arises.

Rated 5 out of 5 by from Perfect I've owned or used Fluke products for all of my professional career so when I needed a meter for home use, the decision was simple: Fluke. Having access to a variety of high-end handheld tools, the 115 gets almost daily use and has never failed me. Personally for me, diagnostics boils done to one question: can I trust the meter to provide accurate information? Without accurate data, you might as be working without a schematic. I have never had an instance where the 115 (or any Fluke product) has given me false or inaccurate information. If my 115 ever dies, you can bet I'll have another...quickly.

Rated 3 out of 5 by from Build quality not as good as I would expect I bought this a couple of days ago. It appears to work okay, but I am disappointed in the build quality. The banana plug on one of the test leads is so loose that I will have to replace the test leads. And the finish on the front panel is not good - looks like poor quality control on the plastic. I expected more from Fluke.

Rated 5 out of 5 by from Beautiful meter I use this meter when working on high-end luxury cars and occasional hobby electronics work and it does great. The values hardly bounce around and it is very easy to read a measurement. I thought the Blue Point one I got from Snap-On was nice but then I used this thing and I realized what a real treat it is to have a nice meter. It could come with some nicer leads though.

Rated 5 out of 5 by from I am a field service tech. For what I need the 115 I am a field service tech, after researching and purchasing this product with the assistance of a sales representative, I am happy to endorse both factory claims and local advise on the product that I purchased. For what I need the 115 is more than adequate, surpasing build and specs of cheaper alternatives. I would prefer to spend my money on something that offers me total peace of mind. I cannot fault this product

Rated 5 out of 5 by from Saved my life My name is joe I am just writing this in hopes to let you know that I have used this meter for a year now and while I was using my 117 last week at work I was saved when I was testing a cabinet and the meter blew up in my hand and then the cabinet flashed but I was able to get move before the cabinet exploded and I suffered some minor injuries but the meter took the brunt of the load and saved my life I owe it all to fluke I will definitely be getting a new meter only from fluke.

Rated 4 out of 5 by from Best for learning and the long haul!!! With 25yrs experience as an aviation/industrial equipment electronic's tech, this has been hands down the BEST meter for training the new guy's without breaking the bank. I have expensive taste, I own a 8060A, 115 ,87V, i1010,and an i30l Plus just about every backprobe,test lead and a whole pile of home made testers. I am very fortunate that I get to go to work and have fun! The best part of my job is taking the new kids, or young men to the side and showing them that this is a line of work where you win some and you lose some. Just as long as we do it with safety first. The reason I bought my 115 was to teach my pups with the same meter they have. Not to say it in a bad way bad way but I can dumb it down to where we can troubleshoot a circuit over the phone, we both have the same meters so nothing is lost in translation.. The Fluke 115 is the best meter hands down when it comes to price and function. I honestly feel that if  you are not using a Fluke, you are taking your own life in your own hands. I trust Fluke that much.

Rated 5 out of 5 by from A Great Starter Meter. I Love It. This meter is a good starter meter. It has a very big display a bright back light, and is very accurate. I use it to electrically diagnose motorcycles. And it gets the job done. Downside is the fuse. It is a very hard fuse to find and is pretty expensive. Advice buy a fuse buddy save yourself 10-18 dollars every time you have that blown fuse accident.

Rated 5 out of 5 by from Dead Nuts On I bought the Fluke 115 because it's small and my application requires moderate accuracy. My biological father works in an electronic test lab, so he said, "Let's plug that 115 into something accurate and see how she does." Although the resolution is less on the 115, even when tested against equipment at 100x the reported accuracy of the 115, the 115 is dead nuts on. +-2% That's why I use Fluke. Their stuff is intelligently designed so you don't have to mess with it. The dial turns with the same thumb you hold the meter with. And it's got capacitance!! What a bonus! My wife is prettier, but my Fluke is more reliable.

Rated 5 out of 5 by from Best meter I have used for car audio Purchase this meter by recommendation by another installer. Has all the settings i need for doing car audio testing as well as general home electrical. LCD screen is clearly visible and has a nice light blue back light, best feature i like it auto cut off. Most meters shut off after 2 to 5 min which is nice but with the fluke it does the same but when testing is done the auto timer resets which is great when doing remote starts/alarms..also love all the attachments thats available

Rated 5 out of 5 by from Great Meter!!!! This is a great meter! I use this for everything, both at work and at home. I trust the accuracy and reliability. The display is easy to read. Two thumbs up!!!!! Great price for a great instrument!
