AstroAI Digital Clamp Meter Multimeter 2000 Counts Amp Voltage Tester Auto-ranging with AC/DC Voltage, AC Current, Resistance, Capacitance, Continuity, Live Wire Test, NCV, Blue

Works fine and appears to be accurate. I’m using it for general purpose DIY stuff so I can’t comment on its accuracy being sufficient for the micro measurements needed for fine electronic components testing, but it did fine measuring the capacitor on my air conditioner (which is not a micro measurement). Continuity, diodes, voltage (both ac and dc) seem to be working fine. I’m used to the old school meters that use a multitude of selector settings so I’m still getting used to the general auto range and function button operation. I consider myself to be a novice, but I already know what those different functions are used for and how easy it is to ruin a meter when used incorrectly, but a 100% complete beginner novice needs to do some reading and develop an understanding of general electrical and electronic functions to get the most out of…well, most any multimeter. If you don’t understand why it’s not a good idea to measure high amp/current flow via direct contact with a handheld multimeter, please do some reading before attempting to do so. I have not tested the non contact voltage function nor the amp/current function via the conductive clamp, but if I have trouble with them, you’ll see it as an edit to this post. I have to say that for the price, this multimeter is extremely well packed with function features. A similar meter from a high end brand would be ten times the price. Again, I just got this one but my experience with entry level price point meters has demonstrated a loss of voltage accuracy over time. (Over time equals 3 or 4. The trick is finding out if it’s years, months, or even days in some cases) There’s no way to calibrate price point meters like what the pros do with the multimeters they mortgaged their house for, so keep that in mind. If you are measuring residential a/c voltage and you’re off by a half or even a whole volt, it’s not really going to make a difference, but if you’re working on a car or inside a computer, a half a volt could be the make or break on your diagnosis. I learned on old school analog meters so I already know multimeters are delicate instruments used to take fine measurements, so do your best to not drop them, don’t toss them in your tool box, do not let them get wet, don’t store them in high humidity or high or low temp environments, change the battery(s) at least annually, and don’t pick them up by the test leads, and they will be more dependable over a longer period of time. If for any reason you let the magic smoke out of your multimeter, it will no longer be good for anything other than a conversation piece. Old school analog meters with all of these functions didn’t even exist and if they did it would be all I could do to lift it and the price would exceed that of the average car. Now I’m not in a faraday cage testing mother boards or printed circuit components, but all things considered, for 40 dollars this multimeter is very impressive and a good buy. I’ve already got 40 dollars worth of value out of it so even if I only get a year of use out of it, I’ll be happy.

it's a great multimeter at a great price and is very accurate in all reading selections. it's cheap enough and accurate enough that you can use it to only read HVAC capacitors, it's cheaper than a replacement probe.

Great amp clamp, works great and seems to have good quality.

Works well enough for a homeowner to do minor electrical repairs. I purchased this simple to test capacitance on my ac compressors capacitor. My old meter did not have this as a function. Plus being 30 years old I needed something more up to date. Seem to be well built but don’t fool yourself. This is not a fluke meter or a Klein but for the price it functions as a good basic multimeter that will handle most homeowners needs. And will be accurate enough for most uses.

UPDATE (After Replacement): After posting my original review, AstroAI reached out and sent me a replacement unit at no cost. The replacement multimeter works exactly as it should and has been excellent so far. It’s clear now that my original unit was defective. The new one does not power cycle when turning the dial, does not shut off unexpectedly, and continuity checks are instant and reliable every time. No missed beeps, no having to cycle modes to wake it up. The rotary switch feels solid, mode changes are consistent, and overall it behaves like a properly designed and assembled meter should. I use continuity and basic electrical checks frequently, and the difference between the defective unit and the replacement is night and day. With a properly working unit, this meter is fast, accurate, and genuinely enjoyable to use. Just as important, AstroAI’s customer support was some of the best in the industry, and their responsiveness and how quickly they handled the situation goes a long way. I’ve left the original video intact in case anyone else is experiencing a similar issue, know that this isn’t standard behavior for this device. Original review below: ------------ There's some sort of design flaw with the dial and the contacts, just cycling through the different modes causes the multimeter to power cycle, sometimes it just completely powers off while changing modes. I use it a lot for continuity checks, and there's been many instances where I touch the leads and they don't register unless I cycle through the modes again. This happens with both the original batteries as well as brand new batteries. The video attached shows the issue, I'm guessing I just have a defective unit because I'd love for it to work as well as it does for everyone else.

This is a perfect tool for every homeowner and diy-er. It is well constructed and works perfectly.

Picked it up because I lost my other meter. I needed something simpler. I don't need every bell and whistle. Just enough to test voltage and make sure power is off. I'll tell ya, I wish I picked it up sooner. The screen is brighter than my old one which is a big deal. I'm getting older and my eye sight is suffering. The bright screen makes it easy to read. The clamp is the best. I was swapping an outlet in my son's room and clipped it to the curtains so I could read it. Lol if it works it works! I consider it pretty accurate and compact. The smaller size doesn't take up much room in my tool bag and the price is right.

Very flexible meter. Easy to use and has all the testing features I will ever need. Reading the user manual is a must because of all the features and functions. Very happy with the display too.
