Review: Reliable, pocket sized and priced well. - I am a diesel mechanic and use this often, this is a reliable small, simple design and inexpensive multimeter that is very helpful for diagnosis. The product offers a audible sound for testing resistance, even a flashlight! and also offers non contact voltage detection feature which comes in handy when searching for a wire through a wall or surface. It functions very well and would recommend If you just need a small multimeter with simple features. The only downside I've noticed is that you cannot select your own mode as it is all automatic but still gets the job done right.
Review: Impressive Low Cost Meter For Just About Anyone - No, it is not industrial quality. And yes, it probably is not something a professional would use for day to day applications. But it's a great economical, (and pretty sophisticated ) little meter that can handle the basic tasks of a homeowner with ease. Let's define what I mean by that last sentence before going on, for all you "Pros" out there: checking to see if an outlet has power or not. Making sure that you turned off the right breaker. Checking for continuity of wires, say going to and from your speakers to an audio source. Is your laptop broken or is the power brick bad? Is it the fuse or is something wrong? There are hundreds of uses for something like this, and the features of this particular economical meter take the guesswork out of setup/use. The Non contact voltage detector on this unit works better than any I have previously used. A great safety feature that can be used by anyone. It lets you know as you approach a dangerous voltage without having to use probes. All other functions are completely automatic, so no more worries about the wrong function or the wrong range or having leads plugged into the wrong location. It does the work for you. Accuracy on voltages compares well to my other meters. The only thing I found about it that I didn't like is it's a bit quirky to get the backlit display turned on without messing with the built- in flashlight; both are good features, but controlled by the same button. One more issue which some others addressed; it does not have current measuring capabilities. And that's a good thing for the average homeowner because attempting to measure current is how the occasional users blow up meters. Period. This is a very nice meter for the money, and way, way above the little 5 dollar ones still being sold or given away; all of which are built with 30+ year old technology. If you are into 480 3 phase, a licensed electrician, or you're a lineman for the county, then keep looking.

## Questions & Answers

**Q: Is there a manual mode?  if you touch probes it goes to continuity but i want resistance. also want to test resistance over v at times**
A: Hi, TM-510 is a multimeter for beginners, only automatic mode, no manual measurement mode.
According to the setting, only the resistance greater than 50 ohms will be detected by the resistance test mode, and it will enter the continuity test mode when the resistance less than 50 ohms is detected.

**Q: What are the multimeter's dimensions?**
A: Thank you for your question, The TESMEN TM-510 Multimeter itself measures 4.8inch*2.4inch and the box measures 6.5inch*3.7inch*2.2inch.

**Q: Does this meter have an auto off feature?  If so, does the meter allow the user to bypass this function so I can keep it on continuously?**
A: Thank you for your question. The TESMEN TM-510 Multimeter has the automatic shutdown function. The meter will automatically turn off if there is no operation for 15 minutes. To cancel the function, you can press and hold the  H/NCV button and the power button at the same time while turning on the multimeter, and the auto-off symbol will not appear at the upper left of the LCD.

**Q: Does this guage temperature?**
A: This multimeter is not capable of measuring temperature.

### ⭐⭐⭐⭐⭐ Beginner-Friendly Multimeter That Makes Testing a Breeze!
*by M***A on April 17, 2025*

As someone with no electrical background, I was a bit intimidated at first, but the TM-510 Digital Multimeter has been an absolute game-changer! This device is incredibly user-friendly, even for a complete novice like me. The smart measurement feature automatically detects what I’m testing—voltage, resistance, or continuity—without me needing to fiddle with settings. The display is clear, bright, and easy to read, and the non-contact voltage function is a lifesaver for safely checking wires. It feels sturdy, well-made, and comes with everything I need, including probes and a handy carrying case. I’ve used it for simple home projects like checking outlets and troubleshooting battery-powered devices, and it works flawlessly every time. This multimeter has given me confidence to tackle small electrical tasks, and I highly recommend it to anyone, beginner or not!
