Amazon.com: AstroAI Digital Multimeter and Analyzer TRMS 6000 Counts Volt Meter Ohmmeter Auto-Ranging Tester; Accurately Measures Voltage Current Resistance Diodes Continuity Duty-Cycle Capacitance Temperature : Electronics

As someone who has carried and used a dmm as a necessary tool for decades, this is above average for occasional use. If you know how to use one. And in reality, good for the price. No, it's not a Fluke, but for 90% of what you use one for, it works fine and it's extremly inexpensive. Sample size of one, it was decently accurate when checked on the Volts, Ohms and Current scales. I measured various start and run capacitors and the readings were plausible. 1% resistors measured within 1%. I asked the vendor about the crest factor for the TRMS readings and they said it was 1.414. So I would be careful with readings of non sine waveforms, VFDs, servo drives, etc. The thermocouple readings are only in whole degrees, so perhaps indicator quality. I have a few gripes like the auto display and shutdown timeouts, but those are a pain on many dmms. Oh, and excessive beeping. I _know_ when I'm switching functions. The unit is supposed to have Cat II and III safety, but this depends on some fuses which are inobtanium in the US. I'm going to ask the vendor about a source. When checking 4-20mA automation signals it's really easy to touch the wrong terminal and blitz the .4A specialty fuse. The leads are short and PVC, but you can fix that. I don't have a means to check frequency and duty cycle handy. Now, retired, it should meet my needs. That is, I'm not going to return it and buy a Fluke. If I was working, I probably would.So my rating would have to be the famous "Good for the money". Spare fuses is an important issue working around 480 V to keep the Cat ratings.Construction seems adequate to me, you should treat your meters carefully. Oh, and one final thing.The magnet strap hanger is worth it's weight in gold working on equipment. I think Fluke's costs more than this meter.Update: Contacted the company, they said they would send a spare. This was a nice gesture, but in industry, to issue or approve the meter for a maintenance crew, it would be manditory to have spares available. It's a special part and the high current interrupting capability is needed for safety and to maintain the CAT rating. An ordinary fuse, if you could find one that fits the holder properly, might maintain an arc in an inductive circuit, destroying the meter and possibly starting a fire or injuring someone. Not as likely in residential power but, at 480 V and above, such things happen.

So far, I have only used the multimeter a few times for basic tasks, but it has performed well. I would say it's a good choice for hobby and DIY use, which is what I bought it for.Readings match my other meters and component specifications, so the accuracy seems to be good. The continuity beep sounds quickly, which is useful when looking for connections on a circuit board.It has several functions that I would not expect in a meter in this price range. It even has a K-type thermocouple for measuring temperature and an adapter for testing transistors. (I have not used either of those functions, yet.)I also like that both amperage inputs are protected by fuses that are easily accessible and clipped it. They should be easy to change, should I ever have one blow.The only negatives so far are, that the instructions do not say how to change the battery, so I had to find a video on YouTube that showed the procedure, and the overall feel of the meter is plasticy and flimsy, but it's no worse than I would expect at this price point.

Well obviously this is not a high end meter at this low price but with a wide range of functionality, 6000 count display and claimed TRMS its still of interest and very useable. Its big in size with a sort of odd looking blue-ish backlight but a large easy enough to read display. Accuracy and update speed are surprisingly good as is repeatability, as always long range reliability remains to be seen. The magnet hanger is a nice idea but needs a stronger magnet to be really useful. Leads are suprisingly decent after a good cleaning of the tips with fine steel wool and alcohol. Overall accuracy seems very good and the meter has an acceptable not overly loud but audible continuity tester and the meter zero's out well when leads are shorted. Both ranges are fused with both the 9v battery and the two small ceramic appearing fuses accessable after removing the battery cover. None of the screws in the case have metal inserts, but again this is a budget meter so not an issue at this price. My worst complaint is though im glad it has a backlight its got a slightly odd look - like many it only stays on a few seconds and when you turn it on theres a weird slightly washed out effect on the numbers, dont get me wrong the display is easily readable just not as vivid and crisp in appearance as others - someone else may not care about or even notice this, and as budget meter its not really an issue. Im not really unhappy as I knew what to expect going in, the meter works well with a lot of functionality offered - but one should keep in mind you can get the Fluke 101 pocket meter now for under $50 and even though not as much functionality its got the robust and proven Fluke reliability thats been shown in tests on YT - just depends on what youre after in a meter - overall this meter is not a bad buy but check other options in this price range, there are some good values elsewhere as well. One might ask why I didnt buy the Fluke 101, a fair question. One answer is this meter offers a lot more functionality, two I already have a fluke 17B but the main reason was simple curiosity based on reviews. I saw decent reviews and a large display with lots of functionality for a low price and im a bit of a meter collector so I bit - this is the kind of meter you dont mind taking with in a toolbox or tossed in the truck etc., get yourself a cheap carry bag to fit online and youre good to go for very little $$. - if someone "borrows" it not much to lose vs. a Fluke or similar priced meter. Even with the little things I mentioned its a good buy and you could do worse for the money, but again lots to see in this price range so have a look but be careful theres lots of junk out there so read and watch any available YT video reviews on any meters youre considering.
