Features and Benefits of the Fluke 365 Detachable Jaw Clamp Meter


Offering a unique jaw head, the Fluke 365 is undoubtedly a unit that stands out in the crowded clamp meter marketplace. But, is the novelty feature of this tool at the expense of functionality? Time to look behind the Wizard’s curtain, and discover how useful this machine is for the serious DIYer and trade pro.

Detachable Clamp Head


Offered by only a handful of machines in the clamp meter arena, the 365 from Fluke incorporates a removable jaw.

Connected to the main unit body by a flexible wire (35.4 inches), this function permits you to secure the jaws around your target cables — while keeping the base machine in an easily readable position. Furthermore, it allows you to access areas otherwise too confined to position a standard clamp meter.

Equally, if you’re more of a conservative type who isn’t impressed by change or novelties, you can keep the jaws attached to the clamp meter, and operate as a traditional unit.

CAT III Certification


If you’re a trade as opposed to a domestic user, the chances are your work projects take you to industrial environments such as warehouses and factories. This being the case, you need a machine that can tackle the big-boy loads concomitant to these locations.

The Fluke Clamp 365 arrives with CAT III (600 volts) certification, permitting you to utilize the tester with three-phase systems — typically of commercial premises. Bear in mind that if your work is seriously hardcore, and you’re dealing with mains utility wiring — such as distributor boxes and pole-to-pole — you’ll need a more hardcore CAT IV model.

Backlight and Flashlight


Whether you’re a serious amateur or trade pro — clamp meter projects can lead you into some dark and poorly lit locations. Engine bays, attics, basements, inside air-con housings — these areas typically lack sufficient light to easily read your circuit tester.

The 365 Fluke boasts a backlit LCD screen, illuminating the generously-sized display promoting effortless data reading. Furthermore, the unit incorporates a rear-mounted flashlight — flooding your target circuitry or wires with welcome light, negating the need for a secondary work lamp or torch.

TRMS and Auto-Ranging


Utilizing TRMS — True Root Mean Square — technology, the Fluke Clamper 365 offers more precise results than its standard RMS model cousins. Checking wave fluctuations instead of simply peak readings, it offers reassuring precision — crucial for work where exactitude is paramount, such as when dealing with microprocessors or circuit boards.

Furthermore, utilizing an intelligent auto-ranging system, the meter automatically selects the correct metric (tens, hundredths, or thousandths) to display on the LCD screen. Meaning not only can novices wield this machine with no knowledge of current or resistance sizes, but also allows pros to switch effortlessly between testing targets without having to adjust the selector dial.

Compact Build


Measuring 8.85 x 2.55 x 1.8 inches and weighing just 9.7 ounces — the 365 from Fluke is a compact unit promoting effortless transportation and portability. Furthermore, its modest size enables you to hold the main unit while wearing restrictive protective equipment.

Multi-function


The Fluke Multi-Clamp Meter 365 promises a number of circuitry testing capabilities. A simple turn of the substantially-sized selector dial allows you to choose between current, voltage, resistance, and continuity.

But that’s it.

Lacking temperature testing, capacitance, and frequency options, some users may find this machine under-specced — especially operators dealing with HVAC systems, AC motors, and PCBs.

Memory Hold


Depressing the Hold button on the front of the 365 main body stores your most recent reading for later scrutinization. This negates the need for you to memorize data, or waste valuable time searching for a pen and paper to note down the result.

Straightforward Operation


Back-to-basics, you don’t need a degree in electrical engineering to operate the Fluke Clamp 365. The front face of the machine is stripped to the essentials, simply including a six-position selector dial, and three buttons. That’s it.

Additional Accessories


When you purchase the Fluke Detachable Clamp 365, you don’t only receive the base testing unit. Included with the purchase are:

  • Testing leads (with in-built storage).
  • Carry strap.
  • Soft carry pouch.
  • Three-year warranty.
  • Multi-language instruction manual.
  • 2 x AA batteries.

What Do Users Say About the Fluke Clamp Multi Meter 365?


In my opinion, the 365 from Fluke is a basic clamp meter with a novel detachable jaw feature — suitable for serious DIYers and general trade electricians.

I have to admit that, despite its removable clamp head, it’s somewhat uninspiring. However, am I being unduly harsh on this machine? To ensure a completely unbiased review, I sourced the opinions of owners of the 365, to explore how this tool functions in real-world situations.

Testimonials from these guys were generally positive. Users praised its compact yet robust build, welcomed the tight-space accessing detachable jaw, and lauded the illumination-boosting backlight and flashlight.

That said, some owners were less than enthusiastic. A few guys commented that the lack of frequency and capacitance severely restricted its project versatility. Furthermore, a couple of DIYers remarked that they would expect a Min/Max function on a basic clamp meter — not featured on the 365 Fluke.

Overall, users of this circuit tester agreed that it was a durable and accurate machine with a welcome removable head.

Alternatives to the Fluke Clamp Electrical Tester 365


If you’re feeling a little uninspired by the Fluke 365 and feel that it’s not ideal for your personal preferences or the requirements of your electrical projects — don’t give up just yet.

Knowing that this machine will not suit all DIYers and trade contractors, I’ve found three alternatives that may be more suitable for your needs.

If you’re a fan of the Fluke brand, yet feel that the lack of temperature and frequency testing in the 365 model is a downer — I may have the answer.

The Fluke 325 remains a straightforward operational machine like the 365, but has the capabilities of testing heat levels to 752 degrees Fahrenheit, and capacitance from 5.0 Hz to 500.0 Hz. Thus making the unit more versatile and with greater suitability for HVAC situations.

  • Doesn’t feature a detachable head, unlike the 365.
  • Includes MIN/MAX readings, not possible with the Fluke 365.
  • Lacks a backlight and flashlight, features of the 365 model.
Should your trade work involve dealing with high-energy loads — such as pole-to-pole wiring or underground mains utility cables — the CAT III rating of the 365 will be insufficient. That being the case, consider this machine.

The CL800 from the respected Klein Tools stable boasts CAT IV (600-volt) certification, making it suitable for extreme electrical voltage and current. Furthermore, lighter on the wallet than the Fluke model, it may appeal more to users watching their budgets than the 365.

  • Temperature testing — not possible with the Fluke.
  • Non-contact voltage, not a feature of the 365 model.
  • Measure frequency and capacitance — impossible with the 365.
If you welcome the basic functions of the 365, but anticipate no requirement for the price-increasing removable clamp head — take a look at this machine also from the Fluke line-up.

The 323, is a comparable machine to the 365. Like its sibling, it lacks frequency and capacitance features, and similarly includes TRMS, CAT III certification to 600 volts, and a memory hold function. But, without the novelty detachable jaw, it’s significantly lighter on the pocket.

  • No backlight or flashlight, features of the 365 model.
  • Like the 365, it checks for continuity.
  • Includes case, testing probes, and batteries — as does the Fluke 365.

Conclusion


Delivering the novelty of a removable jaw head, the Fluke 365 clamp meter will undoubtedly find a welcome customer base — especially among users who demand a confined-space accessing electrical tester.

Its TRMS tech promises pleasing accuracy, while the auto-ranging features save valuable time and eliminate the hassle of fiddling with dials and buttons mid-project. The backlit LCD screen and rear-mounted flashlight will prove welcome in dimly-lit environments, and the CAT III certification delivers pleasing safety for three-phase system testing.

That said, apart from its detachable jaw, it’s a basic clamp meter — lacking temperature, capacitance, and frequency options. And, coming in at a premium price point, it may be out of reach for many amateurs and light contractors.

However, if you demand a machine that’s perfectly suited to dark and restricted-space environments — the Fluke 365 is worthy of consideration.
