ThsindeAuto-Range Digital Multimeter 20000 Counts 4 1/2 DC AC Resistance Capacitance Peak Hold True RMS NCV Diode Tester

I like multimeters and wondered how good a 20000 count $38 meter could be. Well... pretty good!... considering the low price. In a completely unfair test, I compared it to Fluke 289 and Fluke 87V multimeters (which I know to be very accurate). My observations:The Good:. DC Voltage tests (2.5v to 10v) - dead on, very accurate. AC Voltage tests (at household 120V levels) - accurate, within spec. DC current tests - accurate, well within 1%. Continuity tests - quite fast, better than average for a low cost meter. Resistance tests - accurate, well within 1%. Capacitance tests - within spec; the usual 3% - 5% accuracy. NCV - Non Contact Voltage sensor, nice to have, works well.. 20000 count, nice to have. Side effect is that some readings can take a bit longer to settle.. Build Quality - seems better than average for a low-cost Chinese meter. While it does not have the the same heft and quality feel as a Fluke or Brymen, it *does* have an actual removable boot/holster (see photo), a crisp precise selection dial, and decent quality test leads. But like most other inexpensive meters, it does feel somewhat light and plastic-y.. Display is large and readable, sharp and crisp. The secondary readout is nice, but only active during AC voltage tests.The Less Good:. Diode tests - within spec; will light all LEDs but will only read voltage drop for red/yellow LEDs, not green/blue/white LEDs (i.e. anything > 2v drop?). Quite a few meters fail to handle LED testing as they should, so not an uncommon deficiency. Measurement of regular diodes seems to work fine, and produces accurate readings.. Bar Graph - as near as I could tell, the bar graph as implemented on this meter merely reflects the current digital numeric readout. It does not provide the kind of separate quick-reaction display that one sees on more costly meters. Too bad, since this negates most of the usefulness of the bar graph and it becomes merely decorative.. Peak - peak min/max readings seem to be available *only* for AC voltage readings, not the broader min/max capabilities found on pricier meters.. Backlight - works well, but a the backlight LED produces a pronounced uneven lighting on the left side (see photo). Doesn’t bother me much, but some could find this annoying.. Like many Chinese meters, this one beeps every time you turn the selection switch to a new setting: Annoying.. No warnings when the test lead is accidentally left in the10A socket during non-current testing.I took the meter apart and noted that the input protection features are limited, but perhaps a little better-than-average for this price class. The sockets are the usual stamped pot-metal-looking affairs, but the board includes what appear to be decent-sized HRC fuses. The 10M-ohm current limiting resistance is provided by a set of four MELF-type 2.5M resistors. No MOVs to be seen, but but there is a lone PTC. No circuit board cutouts, or other physical shielding, but overall looks perhaps a bit better than the usual cheap-meter average. It claims cat IV 600v rating but I’d hesitate to trust that, and plan to use it only with voltages less inclined to rock my world. See photo...So, not perfect, and not high-end meter quality and features, but still a better-than-average set of capabilities for the price. Should be excellent for general around-the-house tasks, hobbyist use, or as a spare/truck meter.

This is an amazing product for the money. It is easy to use if one reads the instructions (which are very well written and easy to follow). Superior accuracy! Great piece of technology in a nice package.

If you're a professional electronics technician or electrician, this may not be the meter you want except if you're just getting into the business and your employer doesn't supply your test gear. The overwhelming first impression is that this is a Chinese knockoff. It screams it. There are an abundance of features and test leads but the alligator clips that are designed to top the main leads are useless as they do not completely close on their own. It comes with a carrying case, which is not mentioned in the listing, but it is practically useless as it will hold little else than the meter and the main included leads. But it's a nice attempt. I'll be getting a different case.I do like these features: the hard case (yellow jacket in pictures) has places for the test leads which allow for convenient eye-level viewing of the meter, or freeing a hand, when checking breaker boxes and the like. And although the NCV feature is a bit cumbersome it's very nice to have when verifying that dead-man circuits are not live. Although I don't see it being able to distinguish which wire(s) are hot like you can with NCV pens, which for some may make this feature useless. And I really like that this meter is powered by a 9V battery which is much better for those of us who don't use a meter everyday anymore. Intermittent electrical contact of AA or AAA batteries makes most cheap meters a pain to use. Really, any decent meter should be powered by 9V.Unless your experience is that you use multimeters daily and know all the functions, you have to work through them on this meter as the manual is incomplete and poorly translated (annoyingly so). As other reviewers have noted this is no Fluke. They're right. If you use a meter daily in making a living, paying 4 to 10 times as much for a Fluke with comparable features will probably be worth it. But otherwise if you're only an occasional user like me who used to use Flukes daily, this is a reasonable substitute.

Well, for under $50, it rocks! At 1/10th of the Fluke 87V, it only has 0.3% difference in AC readings. Of course, nobody should compare this to a Fluke, but for an all around beater, this is a good multimeter. Now the bad stuff. The attention to details is almost nonexistent. When you open the back screw for putting the battery in, there’s no guide which side is the plus. Fortunately, it won’t die if you put the battery in reverse, which I did at first. The OHM test shows some resistance. I’m not sure if this is because of the leads or internal circuits. It’s always a bad sign to see anything but zero when the leads touch. Measuring house AC showed comparable results to the trusty Fluke 87V within 0.3 percent (was always lower than Fluke). Conclusion is, don’t expect it to perform like a Fluke, but a good all around DMM that you don’t mind your kids to play with. I considered Klein too, but for the price, this wins all the time. Thanks for reading and YMMV.

This product is great the multimeter is almost as precise as some the bench multimeter I’ve used. The added components like the tweezers and thermocouple make this a purchase for the price. Overall, I would recommend this to anyone looking to buy their first multimeter before spending the money on a higher precision multimeter.
