The Top Ten Multimeters for Electronics Technicians
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?
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.
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.
