Features and Benefits of the UEi Test Instruments DL369


It targets light contractors that don’t require the bells and whistles of higher specced machines — but does the UEi DL369 still have sufficient spark to work in trade environments?

Let’s pull back the curtain and reveal exactly what this budget-priced unit has to offer the ambitious amateur and particular pro.

Auto-Ranging


Instinctively selecting the ideal range for current, voltage, resistance, and capacitance with its intelligent tech — i.e., in tens, thousandths, or ten-thousandths — the auto-ranging feature saves the pressured pro valuable downtime by eliminating the need to adjust dials and settings.

Furthermore, it works as an idiot function, permitting you to use the machine if you have no idea whatsoever of whether your electrics should be knocking out two or two thousand volts — making it usable by amateur enthusiasts who lack specific knowledge of circuitry systems.

Theoretically, it may also appeal to contractors who are ignorant of volt and current ranges — but I’d suggest if this is you, you’re probably in the wrong job.

Memory Function


Despite the UEi Clamp Meter DL369 being a rudimentary machine, it still boasts welcome memory features. A Min/Max option allows you to record both the peaks and lows of frequency or current waves, while a HOLD setting permits you to lock your testing results into the machine for later review.

These can be welcome advantages for the busy trade user who lacks the time, hands, or nearby pencil and paper to record the voltage or current while on the job.

CAT III Rating


While the UEi Multimeter DL369’s stripped-back nature makes it a suitable DIY home or garage use unit — at its heart, it remains a contractor-grade machine. With a CAT III safety rating, it’s suitable for three-phase distribution systems — typical of factories and industrial environments.

That said, for the seriously hardcore electrician, it will be inadequate — as utility supplies, high-energy connectors, and first-point electrical meters will demand a CAT IV certification.

Convenience


Designed with the back-to-basics contractor in mind, the UEi Test Instruments DL369 possesses a plethora of features to promote convenience on site.

The rear of the machine includes two recessed storage compartments to safely stow the test probes when not in use. Furthermore, it boasts a low-battery indicator to warn of draining cells — shielding the unit against failure while mid-project. Additionally, the clamp meter arrives with a padded pouch case — permitting fuss-free transportation and delivering welcome protection against knocks and bumps.

Audible Warning System


If you’re a trade electrician — it’s likely that you’ve had your fair share of shocks in the past. Most of the time, these are nothing more than an annoyance, but in high-current situations, they can cause serious injury and even fatalities.

Hence, it’s reassuring to see that the UEiDL369 incorporates a non-contact voltage tester with audible warnings — alerting you to the presence of live electricity without having to make direct contact with the circuit.

Not only useful for pros, but it’s also a virtual necessity for home and DIY users — preventing avoidable accidents.

Straightforward Design


Concentrating on the necessary functions — and omitting those used by solely electrical specialists — the DL369 UEi has a pleasingly straightforward design.

In addition to the substantial rotary function switch, there are just six buttons — NCV (non-contact voltage), auto-range, MIN and MAX, Hz/Duty, and Select. Delivering everything you need for day-to-day circuitry testing — it’s more than sufficient for the journeyman electrician and amateur enthusiast.

Furthermore, the machine houses a generously sized LCD screen for effortless reading. With dual-display, it delivers clamp readings at the top, and probe measurements underneath.

Included Accessories, Warranties, and Guides


They say — whoever ‘they’ are — that patience is a virtue.

Well, these guys have obviously never unboxed a shiny new clamp meter. The last thing you consider doing is being patient — you want to test anything and everything that doesn’t move.

Understanding the excited contractor and DIYer — the UEi big-wigs decided to include everything you need to immediately crack on with your circuitry projects. Arriving in addition to the clamp meter, you receive:

  • Lengthy testing probes.
  • Soft carry case.
  • 2 x AAA batteries.
  • Instruction manual.

What Do Users Say About the Clamp Meter UEiD L369?


In my opinion, the UEi Clamp DL369 is an affordable, back-to-basics circuit tester ideal for the contractor and enthusiastic DIYer.

Yet, with only limited experience with this machine, it’s challenging for me to provide a completely thorough review. Hence, to ensure the ultimate examination of this clamp meter, I investigate the views of owners of the DL 369.

It appears that my thoughts are correct, with users of this unit delivering generally positive testimonials. Guys utilizing the UEi on a day-to-day basis praised its straightforward operation, welcomed the industry-grade CAT III rating, and applauded the audible non-contact voltage feature.

Ok, not everyone was completely won over. One trade pro proffered the view that while the readings provided were accurate, it was slow to determine and display these measurements. Another disgruntled owner bemoaned the fact that the generously-sized LCD screen lacked a backlight — making use in poorly-lit conditions an issue.

However, all owners of the UE iDL369 agreed that this clamp meter was a reliable, fuss-free, trade-level machine that offered accuracy and versatility.

Alternatives to the UEi Clamp Multimeter DL369


If you’ve reached this far in this UEi DL369 review, and are still not convinced by this clamp meter — don’t give up just yet. I appreciate that this machine, with its stripped-back design, may not suit everyone, and so have included below three impressive alternatives.

If the price point of the sub-$100 UEi Clamp Meter appeals, but you’re concerned that it doesn’t incorporate a temperature testing facility for HVAC and automotive applications — check out this machine.

The CL380 boasts similar functions and specs to the DL369, including non-contact voltage alerts, CAT III safety rating, and low-battery warning — but also features a thermocouple to check heat levels from -40 to 1832 degrees Fahrenheit.

  • Features LCD backlight, not included on the UEi model.
  • TRMS tech as opposed to the standard RMS testing of the DL369.
  • A similar price point to the UEi clamp meter.
While the DL369 is designed for contractors, its CAT III rating may make it unsuitable for trade pros who deal with high-energy loads in their daily work life. If this sounds like you, then consider this clamp meter instead.

The CL600 from Klein Tools boasts a CAT IV safety rating, making it suitable for checking mains utilities and distributor boxes. Furthermore, with a wider jaw opening, it’s more suited to checking underground and reinforced cables than the DL369.

  • A comparable price point to the UEi unit.
