What are the best multimeters for electronics technicians? What are some of the best multimeters for electronics hobbyists, especially someone looking for a cheap multimeter that lets you test everything you need to measure?
1. DMiotech Smart
The DMiotech Smart is the best multimeter for electronics hobbyist users. It is affordable. It measures AC and DC voltage, resistance, capacitance, continuity, and frequency. It can test diodes and run the bipolar junction transistor test and live line test. And it measures things in true RMS.
This multimeter has a crystal clear LCD display. Flashlight mode lets you read the display or see what you’re doing in low light conditions. The data hold mode can store a value in memory for quick reference. The built-in stand and wrist wraps allow you to test things hands-free. It only weighs a little over one pound.
This cheap multimeter is compatible with a number of cheap test leads. It has better than average resistance from high voltage and RF interference.
This multimeter runs off of 4 AA batteries and comes with the auto-off feature typically only found in more expensive multimeters. Batteries are not included with the multimeter. If the fuse is burned out, it is easy to replace on your own.
This multimeter isn’t perfect. In a noisy environment, it may run down the battery because it registers background noise as an indication it should stay on. It can’t read resistance in continuity mode, though other multimeters can. It can only measure current for fifteen seconds, after which it needs fifteen minutes to “recover”.
This is an excellent budget multimeter for technicians troubleshooting DIY electronics, though not quite good enough for commercial applications like quality control in an electronics assembly factory.
2. Fluke 287
The Fluke 287 multimeter is available as a stand-alone product and in a manufacturer assembled kit that provides everything from software to probe tips to wireless connections to your computer to save the data as you capture it.
If you buy the multimeter by itself, it costs several hundred dollars. If you buy the entire kit, it costs more than a thousand dollars. However, one of the benefits of the Fluke model is that manuals and CAD models are made available by the manufacturer. This is aside from onboard help screens to guide you through adjusting settings. If you want to know if the multimeter sensors will fit through the access ports of the product you’re designing as part of your testability analysis, this is the multimeter for you.
This is the best multimeter for electronics repair since it logs multimeter measurements as long as you want and can test nearly anything. You can set it to log minimums, maximums, averages, or show graphs of key metrics. The 50,000 dot screen lets you see thousands of recorded vents without having to download data to a computer, though that’s an option, too. You could set it up to automatically track measurements for hours while you go do something else. You can set the range automatically or manually. And the multimeter lets you export data to a computer for further analysis or sending to someone else.
This multi-meter offers a multi-lingual interface, making it perfect for teams with a diverse workforce. It connects and communicates with the Fluke app for data analysis. The connectivity and app let you save data by all your techs in a common location.
Fluke offers accessories from a carrying case and items to let you hang it up while you’re working for hands-free testing to replacement problems. The downside is the cost of Fluke branded accessories.
So what are the cons of this multimeter? It is expensive, as are any accessories. The Fluke app wants to access your media and photos and doesn’t work on all Android devices. While Fluke has good technical support for its hardware, it has poor service for its apps. If you want full functionality from the app, you have to pay an extra subscription for it.
3. Amprobe 30XR-A
This multimeter is available with and without various probes. You pay more for temperature and capacitance probes. This multimeter is available with a NIST certificate, though you pay for that certification. NIST calibration ensures high levels of accuracy and may be contractually required for electronics manufacturers or electricians and repair technicians.
The unit has auto-ranging; this is a major time-saving feature. It has basic data collection and presentation; it shows minimum and maximum values and can hold data for a while. It updates automatically several times a second. It shows a low-resolution analog bar graph.
This unit comes with a holster and hanging strap. It is durable and rugged.
The cables it comes with don’t let you change the probe tips. It is compatible with a number of affordable generic probes. The leads that come with the unit cannot be gator-clipped. It warns you when you’ve put the test leads in incorrectly.
It has an automatic power-off to save the battery, though the backlighting is weak. It has a good 10 amp fuse you’ll almost never have to change.
What are the downsides of the Amprobe 30XR-A multimeter? This unit lacks a serial interface. The continuity check is slow. The quality of the fuses is not always up to expected standards. They go out more often than you’d expect.
This is the best multimeter for home use if you need a basic, broadly usable unit.
4. Fluke T5-1000 1000-Volt Continuity USA Electric Tester
The basic model of this multimeter costs just over a hundred dollars. If you buy it with calibration data, it doubles the cost. This premium version comes with NIST-traceable calibration and certification. Yes, you get a calibrated multimeter from Fluke, especially if it is one of the “package” deals.
The Fluke T5-1000 offers very high resolution whether you’re measuring AC or DC voltage. The name for this model comes from the fact that it can test voltage from zero to a thousand volts. It offers OpenJaw measurements.
It beeps to inform you when the circuit has continuity. It is ideal for basic troubleshooting.
It has detachable probe tips, but the probes that come with it are very narrow and versatile. This multimeter is compatible with Fluke clips. Compatible probes are sold separately. It is compatible with the Fluke infrared thermometers, voltage detector kit, and other sensors.
It has an auto-off mode to extend the battery’s life. It comes with two AA batteries. In some regards, the battery life for this multimeter is better than average because it lacks reliable backlighting.
It is quite durable; it is rated to survive a ten-foot (three-meter) fall.
A holster for this multimeter is sold separately. However, it is compact and convenient to carry without a holster. The multimeter itself is light, weighing in at just over a pound.
What are the downsides of this multimeter? The backlight sometimes flickers. It is expensive compared to other multimeters. The capacitance function sometimes fails altogether.

Questions & Answers
Question: I used my multimeter on the continuity selector switch. Now, it displays for only a few seconds, and then goes off after I put new batteries. What's the solution?
Answer: Continuity means you were testing for current in a circuit. You may have overloaded the multimeter, shorting it out. It may need a fuse replaced, assuming something else isn't burned out.
