Multimeters are one of the most important tools an electrician can have in their toolbox. Mostly used for testing electrical voltage, resistance, and continuity, a multimeter is essential for everything spanning from troubleshooting a light switch, to checking the functionality of an old extension cord, to testing batteries, and more. These compact little units are also an important part of remaining safe on the job site, by answering questions like “is this switch on?” or “is this wire broken, or is it still conducting electricity?” For all these reasons, we recommend choosing a high quality multimeter that’s built to last.
In this review, we’re going to walk you through the Klein MM700 Multimeter so you can learn if this is the right unit for you and your unique needs. Spoiler alert: this multimeter is considered to be one of the best on the market. Here’s why.
Klein MM700 Features
This multimeter is known for being highly accurate due to its use of True Root Mean Square (TRMS). Compared to instruments that use just Root Mean Square (RMS), multimeters with TRMS are much more accurate when reading AC currents. This is an automatic feature of this multimeter. The Klein MM700 also offers a diverse number of capabilities, including testing electrical frequency, diodes, temperature, capacitance, continuity, and duty-cyle.
This multimeter is built to measure up to 1,000 volts in AC/DC current, 40M in omega resistance, and 10A AC/DC current. One useful feature of this unit is its low impedance mode, which gives you the ability to identify stray voltages. In terms of durability, this multimeter also excels. It’s designed to withstand drops of up to six-and-a-half feet high, in case it slips out of your hands while you’re on a ladder. Last but not least, the Klein MM700 comes with a Category IV 600 volt safety rating.
Klein MM700 Performance
This multimeter is a high-quality unit that is known for providing superior performance on job sites. Due to its TRMS capability, the Klein MM700 is known for an extremely high level of accuracy. It also delivers readings quickly and efficiently. Some reviewers have noted that the accuracy of this multimeter starts to diminish when you’re taking readings of higher currents. But that doesn’t mean there’s reason to worry—the truth is this is a common problem that virtually every multimeter has. Overall, this multimeter provides highly accurate measurements, especially compared to competing units, and is more than sufficient for virtually every job type. You can also quickly and easily re-calibrate this unit, which is recommended before starting a new job for the highest levels of accuracy.
The versatility of this multimeter means that it can be used for everything from AC/DC testing, to finding and eliminating ghost voltages, or stray voltages. The interface of this unit is extremely easy to use and intuitive, so electricians don’t have to worry about wasting time trying to learn how to use the various features. The Klein MM700 also comes with a built-in back light that makes it ideal for both extremely sunny, and dark or nighttime conditions. No matter where you are, or what time of day, this multimeter is easy to use and read.
Klein MM700 Quality
Klein Tools understands that when you’re working as an electrician, sometimes tools get dropped, banged up, and generally have to face the wear and tear of being one of many heavy tools in a crowded toolbox. That’s why they put an emphasis on making sure their products can take a beating, and the Klein MM700 is no exception. This multimeter is built to withstand drops of heights up to six-and-a-half feet, so whether it accidentally falls off a ladder or a coffee table, you can rest assured that it will survive the fall and continue functioning as normal. This device is also known for having strong probes, for high quality readings every time.
Klein MM700 Customer Review
If you’re an electrician who frequently works on construction sites, this is a great unit for you. It’s got a nice big, bright, and easy to read screen. It’s super durable and comes with a great little carrying case. One feature that I enjoy is that when you switch into the resistance/diode/continuity test setting, it automatically defaults to continuity first. If you’re used to using meters like this one, you know that you’re going to be using the continuity setting much more often than the resistance setting, so it’s just a small intuitive feature that makes a big difference in terms of user experience. It’s true that it’s tough finding a good way to attach this meter to your tool belt, but it’s really not the big deal that some reviewers make it out to be. I recommend spending $10 additional dollars to buy the magnetic holder for this meter.
