Milwaukee Clamp Meter Kit (NIST)

As an electrician and tool enthusiast, I often find myself evaluating various tools to ensure they meet the rigorous demands of the field. Recently, I had the opportunity to test the Milwaukee Clamp Meter Kit (model 2235-20NST), and I must say, it left quite an impression. Milwaukee has been a reputable name in the tool industry, primarily known for its power tools, and this clamp meter is an extension of their commitment to quality and functionality.

Design and Build Quality

The first thing that struck me about the Milwaukee Clamp Meter is its robust build. The tool feels solid in hand, with a rugged over-molding that not only enhances durability but also offers a comfortable grip. This is particularly important for fieldwork, where tools are often subjected to rough conditions. The overall length of 7 inches makes it compact enough to fit comfortably in my tool belt, and despite its sturdy construction, it’s surprisingly lightweight.

The large 1.0” jaw opening is a thoughtful design choice, allowing for easy measurement of wires in panels or bundles. I found the thin jaw profile especially useful when working in cramped spaces, a common scenario in both residential and commercial environments.

Functionality and Performance

The Milwaukee Clamp Meter boasts a range of features that are essential for any electrician. It measures up to 400 amps AC, which is more than sufficient for most residential and commercial applications. The True-RMS functionality ensures accurate readings, even when dealing with non-linear loads, which is a significant advantage over standard meters.

One feature that I found particularly useful is the built-in LED work light. Working in poorly lit areas is a common challenge, and this small addition makes a big difference. The black-on-white display with backlight is another thoughtful feature, ensuring the readings are easily visible even in low light conditions.

In terms of safety, the tool is rated CAT III 600V, providing a reliable level of protection for various electrical environments. This is crucial for peace of mind when dealing with potentially hazardous situations.

Practical Use and Limitations

During my tests, I used the clamp meter for a variety of tasks, from measuring the current draw of a furnace blower motor to diagnosing electrical issues in a malfunctioning chain hoist. The meter performed reliably, providing accurate readings each time.

However, there are a few limitations that I feel are worth mentioning. Firstly, the meter does not come with a case or any form of cord management. This oversight means that the leads are prone to getting misplaced, especially when switching between different functions. Including a case or a cord wrap would significantly enhance the user experience.

Another minor drawback is the absence of a magnet or a strap for hands-free operation. This isn't a deal-breaker, but it would certainly make the tool more convenient to use in situations where both hands are needed.

Battery Life and Power Management

One critical issue I encountered was with the tool’s power management. The meter’s off dial doesn't completely turn off the device, which can lead to unexpected battery drain. This is a significant inconvenience, especially when you find yourself with a dead battery in the middle of a job. I had to resort to removing the batteries when not in use to ensure they didn’t drain. This is an area where Milwaukee could certainly improve.

Accuracy and Reliability

When it comes to accuracy, the Milwaukee Clamp Meter generally performs well. However, I did notice some inconsistencies when measuring resistance. The meter reads resistance in whole numbers rather than decimals, which might not provide the level of detail required for some applications. Additionally, it struggled with low ohm readings, which could be a limitation for certain tasks, such as diagnosing issues with motor windings or other low-resistance components.

Overall Value

Despite its few shortcomings, the Milwaukee Clamp Meter offers excellent value for its price point. The combination of robust build quality, essential features, and reliable performance makes it a solid choice for both professional electricians and serious DIY enthusiasts. The five-year warranty is also a testament to Milwaukee’s confidence in the durability of their product, adding an extra layer of assurance for users.

Recommendations

Would I recommend the Milwaukee Clamp Meter? Yes, but with some reservations. For general use in residential and commercial settings, it is a reliable and efficient tool that will meet most of your needs. Its sturdy build, ease of use, and essential features make it a strong contender in its category.

However, if you require extremely precise resistance measurements or rely heavily on low ohm readings, you might want to consider other options. Additionally, if battery life and power management are critical concerns for you, be aware of the potential for unexpected battery drain with this model.

In conclusion, the Milwaukee Clamp Meter Kit (2235-20NST) is a commendable tool that offers a lot of value for its price. With some minor improvements, it could easily become a top choice for electricians across various fields. For now, it remains a reliable and robust option that I would confidently recommend for most electrical tasks.
