Milwaukee Cordless Lithium-Ion Clamp Meter

The Milwaukee Cordless Lithium-Ion Clamp Meter, model 2239-20, is a tool that promises a lot on paper. As someone who often finds themselves in commercial and industrial environments, I was eager to see if it could live up to its claims.

First impressions matter, and Milwaukee has done a commendable job with the design of this clamp meter. The ergonomic pistol grip design is a standout feature, making it comfortable to hold, especially during prolonged use or when working overhead. This design choice is not just about aesthetics; it genuinely reduces hand fatigue, which is invaluable during long workdays.

One of the most notable features is the 1.57-inch jaw opening. This wide opening allows the meter to handle large conductors with ease, making it versatile for a variety of applications. Whether you’re working on HVAC systems, electrical panels, or general maintenance tasks, the wide jaw opening is a significant advantage.

The true-RMS current measurement capability is another highlight. True-RMS meters are essential for accurate readings, especially in environments with non-linear loads or electrical noise. This feature ensures that the readings are reliable and precise, which is crucial for diagnosing and troubleshooting electrical issues.

Equipped with non-contact voltage detection, the meter adds an extra layer of safety. This feature allows you to detect voltage without making contact with live wires, reducing the risk of electrical shocks. The built-in LED floodlight is another thoughtful addition. It provides ample illumination in low-light conditions, such as basements, utility closets, or crawl spaces, ensuring that you can see what you’re working on without needing an additional flashlight.

The meter’s wide current range of up to 1000 amps AC/DC and voltage range of up to 1000 volts AC/DC make it suitable for a broad spectrum of applications. These ranges are more than sufficient for most commercial and industrial tasks, giving you the flexibility to handle various electrical systems with a single tool.

However, despite these impressive features, the meter is not without its flaws. One of the primary concerns I encountered was the accuracy of the readings at lower ranges. While the meter performs admirably at higher currents and voltages, it tends to struggle with precision at lower levels. This can be a significant drawback for tasks that require high accuracy, such as troubleshooting sensitive electronic circuits or ensuring compliance with strict electrical standards.

The placement of the test lead ports at the bottom of the meter is another design choice that could use some improvement. When lifting the meter, the leads can easily get caught on objects and pull out of the ports. This issue could be mitigated by relocating the ports to the front of the meter, allowing for more secure and convenient connections.

Another area where the meter falls short is the lack of a carrying case. Given the investment in a quality tool like this, it’s surprising that Milwaukee did not include a storage solution. A carrying case would not only protect the meter but also help keep the test leads and accessories organized. Additionally, the inclusion of a temperature input that uses a K-type connector would have been a valuable addition. K-type connectors are widely available and easy to replace, making them a practical choice for temperature measurements.

Despite these shortcomings, the meter does have several redeeming qualities. The auto-off function is a practical feature that helps conserve battery life. It’s easy to forget to turn off the meter after use, and this function ensures that the batteries last longer. Speaking of batteries, the meter is powered by two AA batteries, which are readily available and easy to replace. However, you do need to remove a couple of screws to access the battery compartment, which can be a minor inconvenience.

The high-contrast display screen is another strong point. The white-on-black display is easy to read, even at odd angles or in bright sunlight. This is particularly useful when working in challenging environments where visibility can be an issue. The side-mounted dial for one-handed use is also a thoughtful design element, allowing for easy mode selection without needing to use both hands.

In terms of build quality, the meter feels robust and well-constructed. Milwaukee has a reputation for producing durable tools, and this clamp meter is no exception. The rugged overmolding adds an extra layer of protection, making it suitable for use in tough environments.

The inclusion of a temperature probe in the package is a nice touch. It’s always a bonus when manufacturers include essential accessories, saving you the hassle and expense of purchasing them separately. The meter also comes with part numbers for replacement test lead sets and temperature probes, making it easy to find compatible accessories when needed.

Despite its flaws, the Milwaukee Cordless Lithium-Ion Clamp Meter has a lot to offer. It’s packed with features that make it a versatile and valuable tool for professionals in commercial and industrial settings. However, the issues with accuracy at lower ranges and the lack of a carrying case are significant drawbacks that cannot be overlooked.

Would I recommend this tool? It depends on your specific needs. If you require a meter with a wide current and voltage range, robust build quality, and useful features like non-contact voltage detection and an LED floodlight, then this meter is worth considering. However, if precision at lower ranges and convenient storage are critical factors for you, you might want to explore other options.

In conclusion, the Milwaukee Cordless Lithium-Ion Clamp Meter is a solid tool with some room for improvement. It’s a good addition to any professional’s toolkit, but be aware of its limitations and weigh them against your specific requirements before making a purchase.
