When the battery voltage is lower than the operating voltage, the Low battery icon is displayed in the upper right corner of the display.
Continuity Test
Connect the contacts at both ends of the test lead, and it will automatically switch to the continuity mode. The buzzer will sound and the indicator light will glow green.
High-Quality Battery
The multimeter is equipped with high-quality batteries to enhance user experience.
Multimeter Protector
This digital multimeter has a protective cover to protect the multimeter from physical damage.
Compact Design
This voltage tester is compact and doesn't take up much space.
Storage Bag
It is equipped with a sturdy storage bag for easy carrying and storing of the multimeter and test leads.
Easy to use
Step 1. Please remove the rubber sleeve behind the multimeter, open the battery back cover, and put 2 AAA batteries into the battery compartment according to their polarity marks. Place the battery cover back on.
Step 2 Turn on the multimeter, insert the test leads according to the prompts, and enter the test after the two ends of the test leads are in contact with each other for calibration.
Step 3. To measure AC/DC voltage, resistance, or continuity. Insert the test leads into the multimeter and connect them to both ends of the measured object. The multimeter measures automatically without user selection.
Note: No need to use test leads if you want to use the NCV function.

I had 2 old multimeters in which the batteries had corroded. I needed a new meter for some electrical work I was doing at home. This device is fantastic. It always selects the right function before you need to use it and the display is excellent. I would highly recommend this multimeter for the “home” electrician that needs a well-made multimeter. I really like it!

Just like the title says, this is a great value for your money. if you need a simple to use, I mean very simple to use inexpensive multimeter, this is the one. It's virtually foolproof to use! Anybody who has never even used a multimeter can start using this one from the get-go. All the functions are automatic, AC/DC voltage, resistance and continuity. I've used it to check voltages around the house and it's performed flawlessly. I haven't yet checked resistance as I'm not a power user to have resistors laying around. It also has a feature to check electric plugs/wires to see if they are live wirelessly, it has a backlit display and a very small LED flashlight. To be honest the flashlight is super dim, but hey! It's better than nothing I suppose. It also has nice build quality and like I said, it's a very good basic foolproof household multimeter.It was very nice also that it came with genuine copper top brand name batteries, a carrying case and a very well-written instruction book that was very detailed and concise in explaining its use. Amazing how fast technology advances as a multimeter like this would have been over $150.00 years ago and so far, I'm very happy with it. And for the price you really can't beat it. And say goodbye to those old-fashioned dial multimeters that were honestly such a pain to use. I highly recommend this Tesmen TM-510.

I recently purchased the TESMEN TM-510 Digital Multimeter, and I have been extremely impressed with its performance and features. The 4000 counts display provides clear and accurate readings, making it easy to measure various electrical parameters with precision. One of the standout features of this multimeter is its smart measurement capabilities. The auto-ranging function allows the multimeter to automatically select the appropriate range for the measurement being taken, saving time and ensuring accurate results. This feature is especially helpful for beginners or those who may not be familiar with manual ranging. I also appreciate the build quality of the TESMEN. It feels sturdy and durable, making it suitable for both professional and DIY use. The ergonomic design and easy-to-read display make it comfortable to use for extended periods. Overall, I highly recommend this multimeter to anyone in need of a reliable and versatile tool for electrical measurements. Its smart features, auto-ranging function, and durable construction make it a valuable addition to any toolbox, especially mine.

Comes in reclosable box and zippered storage case. The zippered case has a pocket to store the leads. I was surprised it came with 2 Duracell AAA batteries instead of the usual generic ones.I tested the NCV function near a plug socket and worked great show an H for high voltage. Also used it with leads on the socket and worked fine. Tested an 1.5V AA battery with it and displayed 1.47 so seemed accurate.The multimeter has a rubbery or silicone removable outer casing to help protect it. It's lightweight and easy to use. You can press a button to backlight the screen or turn on a small LED light on the back.CONS: Has one of those tiny screws to hold on battery compartment cover. Not so convenient to unscrew as you need a screwdriver small enough and I can see the screw dropping and getting lost. Would have preferred LED light on top of device so easier to aim the light and read in the dark. Now realize I would have preferred a non-automatic multimeter where I could select the function, but that's my fault.Overall good multimeter and the automatic function is probably great for basic home user.

I picked up this multimeter for a little project I am doing that needed a bit more precision than my cheap dollar store multimeter (which surprisingly worked well for what it was). I decided I wanted something that didn’t require me turning dials and determining which associated metric was needed to be read so this device was perfect because it offered automatic detection.I decided to test it in a couple ways. I tried the auto sensor to test if current was running through various outlets, switches, and sockets. It picked up current on most of my switches, but this was over the plate so it is understandable if it didn’t detect anything. For power outlets it picked up current on all but one, which it detected a little bit but that outlet also had the protectors in it. And for the sockets it picked it up right away. I also held it to the lights and if I flipped the switch it would detect when it was off or on.I tested the multimeter on various batteries and it picked up the correct value right away.I also used this on a device I made that contained 5k potentiometers . It automatically went in ohm mode and accurately measured the pots, even identifying that while some were in the margin of error were not exactly 5k.Overall this device was perfect. It was easy to operate and read. It even had a backlit screen. It is small and comes with a nice case that holds its cables. It even had a little cover that slips over so that it is kept safe from bumps. Perhaps it provides for insulation just in case. The manual is nice too and comes in various languages.For 10 bucks this is worth it.

I recently purchased the TESMEN TM-510 Digital Multimeter and it has exceeded my expectations. The 4000 count display is clear and easy to read, making measurements a breeze. Its smart measurement feature and auto-ranging capability are standout aspects, allowing for accurate readings without the need for manual range adjustments. The non-contact voltage function is a great safety feature, especially when dealing with AC/DC voltage testing. It also efficiently measures resistance and continuity. The green color of the multimeter gives it a unique and professional look. It's a reliable and user-friendly tool for both professionals and hobbyists. Definitely a great value for its price!
