I was tired of lugging a bulky multimeter around my jobsite just to check a quick voltage or capacitance reading. That’s why I tested the Fluke 107 AC/DC Current Handheld Digital Multimeter, Gray โ it’s palm-sized at just 0.2 kilograms and still measures AC/DC voltage, current up to 10A, resistance, and capacitance.
This meter is really for electricians and technicians who need to work fast and safely in tight spaces. The backlit display and data hold keep you moving without squinting, though I wish the included test leads were a bit longer for deep panels. Still, the CAT III 600V safety rating gives me real peace of mind on live circuits.

Where it beats the main product: It has a higher CAT IV 600V safety rating and measures temperature, making it the go-to for industrial panels and motor controls.
Where it falls short: It’s significantly larger and heavier at over 0.5 kilograms, so you won’t want to carry it in your pocket all day.
If you need true RMS for VFD work and can handle a bit more size, the Fluke 115 is my pick over the 107. But if you’re doing heavy industrial troubleshooting with high-voltage gear, I’d go straight to the Fluke 87V despite its bulk โ the CAT IV rating and temperature measurement are worth the extra weight. For everyday carry and quick checks on CAT III circuits, the 107 still wins for me.
How It Actually Performs
Palm-Sized Portability & Handling
The first thing I noticed is how light this thing is โ at just 0.2 kilograms, it genuinely disappears into my shirt pocket. I spent a full day walking between panels on a commercial job site and never once felt weighed down. The magnetic lanyard is a smart touch too; I clipped it to a metal junction box and had both hands free for probing. The only catch is the lanyard can slide off smooth plastic panels if you’re not careful.
Accuracy & Measurement Reliability
I tested the Fluke 107 against a known 120V AC source and a 9V DC battery, and the readings were spot-on every time. The data hold button works flawlessly โ I can take a measurement, freeze it, and then move the meter into better light to read the backlit display. For capacitance testing, it picked up a 10ยตF capacitor without any drift. I wish the spec sheet explicitly stated true RMS, but for basic sine wave circuits, it’s dead accurate.
Safety & Build Quality on Live Circuits
With its CAT III 600V safety rating, I felt comfortable using this meter on 277V lighting circuits and 480V motor controls. The TL75 test leads feel durable and have hard points that stay put on terminal screws. I accidentally dropped it from about 3 feet onto concrete, and it survived with only a small scuff on the grey casing. That kind of toughness is what I expect from Fluke, and the 107 delivers.
Battery Life & Daily Usability
The meter runs on two included AAA alkaline batteries, and after two weeks of moderate daily use, the battery indicator still shows full power. The backlit display is bright enough to read in dim mechanical rooms, though I wish it had an auto-off timer to save juice when I forget to turn it off. For quick checks on voltage, resistance, or frequency, this meter is ready to go the moment I pull it out of my pocket.
Who Is This Multimeter Best For?
After weeks of carrying the Fluke 107 AC/DC Current Handheld Digital Multimeter, Gray on real job sites, I have a clear picture of who will love it and who should keep shopping.

Common Issues & Fixes
I’ve put the Fluke 107 through its paces, and while it’s a solid meter, I ran into a few hiccups. Here’s what I found and how to handle them.
Magnetic Lanyard Slipping Off Panels
The problem: The included smart strap magnetic lanyard tends to slide off smooth plastic or painted metal panels, leaving the meter dangling dangerously.
My fix: I attach the lanyard to a ferrous metal surface like a screw head or conduit clamp instead of flat panels. For plastic enclosures, I just loop the lanyard around a nearby wire or hook.
Short Test Leads in Deep Panels
The problem: The TL75 hard point test leads are about 40 inches long, which isn’t enough to reach deep into large electrical panels or behind tightly packed terminals.
My fix: I bought a set of longer, silicone-insulated test leads with right-angle connectors. They give me extra reach and flexibility without compromising the CAT III safety rating.
Backlit Display Draining Batteries
The problem: The backlit display stays on until you manually turn it off, and I’ve accidentally left it on overnight, draining the included AAA batteries faster than expected.
My fix: I make a habit of pressing the data hold button to turn off the backlight before putting the meter away. I also keep a spare set of AAA batteries in my tool bag for emergencies.
Reading Fluctuations on Noisy Circuits
The problem: On circuits with variable frequency drives or switching power supplies, the voltage reading can bounce around because this meter doesn’t have true RMS capability.
My fix: For noisy circuits, I switch to the frequency measurement mode first to get a stable baseline, then use the data hold to freeze a voltage reading after a few seconds of settling.
Warranty & Support
The Fluke 107 comes with a 1-year manufacturer warranty, which covers defects in materials and workmanship. I’ve heard Fluke’s customer support is reliable โ you can call them directly or register the meter online to get replacement leads or troubleshoot issues quickly.

Frequently Asked Questions
Is the Fluke 107 true RMS?
No, the Fluke 107 does not have true RMS measurement. I tested it on a standard sine wave and it was dead accurate, but if you’re working with variable frequency drives or other non-sinusoidal waveforms, you’ll want to look at the Fluke 115 instead. For basic residential and commercial circuits, this meter handles everything I’ve thrown at it just fine.
Can I measure DC current up to 10 amps with this meter?
Yes, absolutely. The Fluke 107 has a dedicated input terminal for AC and DC current measurements up to 10 amps. I used it to check a motor draw on a small pump and got a clean, stable reading. Just remember to move the test lead to the correct input jack before switching to current mode.
What safety rating does this multimeter have?
It carries a CAT III 600V safety rating, which means it’s designed for use on commercial and industrial circuits like distribution panels and motor controls. I’ve used it on 277V lighting circuits and 480V equipment without any concerns. It’s not rated for CAT IV environments like utility meters, so keep that in mind for heavy industrial work.
How long do the batteries last in the Fluke 107?
The meter runs on two AAA alkaline batteries that come included in the box. After about two weeks of moderate daily use โ mostly voltage checks and continuity tests โ the battery indicator still shows full charge. That said, I accidentally left the backlight on overnight once and noticed the battery drain a bit faster, so I always turn it off manually now.
