Customer Reviews
Customer Review: “The VDC/VAC/OHMs is very acurate. The IDC/IAC current as tested by others is also very good. The dispaly is bright and well laid out. The probes are 2nd rate, but work. The lower auto scale only goes down to 5V. You must push the soft key “V” to go to the milivolt scales. Same with VAC. The VAC/IAC True RMS only works for 20Hz to 1KHz accuratly. This is NOT a good audio amplifier analyser. The frequency counter reqires 1 to 2 V to work. The diode voltage appears to be really bad (others tested). Continuity works. The Capaitance measurement is not so great. Get a good LRC meter. Tempertaure, who cares, I have dedicated meters for that. I wanted a data logger. This works. You must first save up 1,000 points on the internal memory. Then use the software to down load and save. Excel doesn’t like the file but it opens. I have Labview and NI VISA loaded on my machine so I don’t know if it will effect you. I pluged in the usb cable and my hadrware manager recoginized it immediantly. Loaded software, set the com port to 6, and it worked first time. Data is not time stamped. If you want to see the faboulous accuracy, try you-tube videos. These people have very expensive equipemnt needed to test a 55,000 count meter. Over all, for me this was an excellent purchase.”
Customer Review: “I love this meter! It’s fairly compact, lessening its footprint on my work bench. So far, at least for my uses in building guitar amplifiers, I’ve not even needed to consult the instruction manual. But, it did catch me out, initially, as I couldn’t get it to power on! I guess I’m a bit too old school, as I expected it to turn on the moment I pressed the power button. That’s been the only reason I’ve consulted the instructions, so far. But, it didn’t help. I really felt like a fool when I had to ask the community how to turn it one! So, for any other old timers out there, like a lot of modern electronic devices, the button must be held down for about 3 seconds to power the thing up. One thing that I really liked, that my old Fluke® (far more expensive) meter couldn’t do, is to illuminate an LED, while displaying its forward voltage. I suppose there could be even better options out there, but I’m very satisfied with this unit, as long as it continues to work. Should that change, I’ll post an update.”

Customer Review: “This is only preliminary; I’ll update if I see anything.I got spoiled at work with really nice (but older) gear. See, I was responsible for checking the calibration of all of our in-house test equipment and they wanted me to have at least one level better, AND it was calibrated regularly. Now that I’m just a hobbyist, it’s hard to justify a $500 used meter. On the other hand, I’m restoring some vintage sound equipment and calibrating it requires more resolution than the typical hand-held 3½ digit meter. And there are times that resolution is more important than absolute accuracy, as long as it’s repeatable… comparing two readings or a change in reading, things like that.”

Customer Reviews
Customer Review: “The OWON XDM1041 Portable Digital Multimeter has quickly become an indispensable tool in my electronics toolkit, offering exceptional performance, reliability, and versatility in a compact and portable package. As someone who values precision and functionality in measurement instruments, I am thoroughly impressed by the capabilities and features of this digital multimeter.”
Customer Review: “This goes for any meter. Don’t trust the last digit. Between probe contact, environmental noise and rounding error, it’s not going to be useful for anything other than comparison. (e.g., matching resistors.) That means that effectively it’s really a 5500 count meter, but that hand-held is probably a 199, 320 or 550 count. In other words, the difference is actually more pronounced than it would appear. The lower resolution is fine for most applications. Do you really need to know that the NiMH cell in your hand has 1.2345V instead of 1.23V? On the other hand, calibrating analog electronics often does require this kind of resolution.”

- Display: A clear, large, backlit LCD or TFT screen is essential for comfortable reading, especially during long work sessions. Dual display capabilities can be a huge time-saver.
- Connectivity and Data Logging: For advanced users, USB, Ethernet, or RS-232 connectivity for PC control and data logging is invaluable. This allows you to record measurements over time, analyze trends, and even integrate with other lab equipment like a digital oscilloscope for comprehensive diagnostics.
- Build Quality and Durability: A good bench top multimeter should feel solid and well-built, capable of withstanding the occasional bump or spill on a busy workbench.
Budget Planning
Your budget plays a significant role in your choice. Entry-level bench multimeters can be quite affordable, offering good basic functionality and improved accuracy over handhelds. Mid-range options introduce higher counts, True RMS, and better data logging features. High-end professional-grade units provide superior accuracy, more extensive features, and often remote control capabilities. Think about how often you’ll use it and the precision level you truly need. Sometimes, a slightly higher investment upfront can save you headaches and provide more reliable results in the long run.
Final Thoughts
Ultimately, the best bench top multimeter for you depends on your specific applications. If you’re a hobbyist working on small projects, a model with 30,000-55,000 counts and True RMS might be perfect. For professionals or those involved in precision engineering and testing, a 5.5-digit meter with extensive data logging and communication options would be more suitable. Always prioritize True RMS for accurate AC measurements and consider the display quality for ease of use. A well-chosen multimeter will be a cornerstone of your electrical toolkit for years to come.
