Review: Good buy. I already got my monies worth out of it. - 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.
Review: Initial defect, but excellent performance after replacement - 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.

## Features

- Versatile Digital Clamp Meter: Accurately measures AC/DC Current, AC/DC Voltage, Capacitance, Frequency, Duty Cycle, Resistance, Diode, Continuity and Live Wire Tests. This clamp meter is a really useful tool for solving industrial and household electrical issues.
- Non-contact Voltage Testing: This Clamp Meter features non-contact voltage testing with sound and light alarms. When the Meter senses a weak AC signal, the green indicator light will come on and the buzzer will emit a slow, audible beep. when the Meter senses a strong AC signal, the red indicator light will come on and the buzzer will emit a brief beep.
- Multifunctional & Easy to read: Support Data Hold, Max/Min, Auto power off after 15 minutes inactivity, low battery indicator and continuity buzzer. The LCD Backlit Screen and Flashlight make it easy to use in a dark working area. ZERO function decreases the data error influenced by the Earth’s magnetic field, and helps you to obtain a more accurate measurement.
- Large Jaw Opening: The jaw opening measures current in a conductor without touching or interrupting the circuit. Its slim and compact size makes it easy to operate in narrow spaces. This clamp meter has passed the environmental pollution test degree 2 and overvoltage category III 600V safety standards.
- Additional Tips: To measure the current you need to clamp the meter around one of the wires and not the whole power cord. Ensure the conductor to betested is in the center of the clamp head. The clamp Jaw is only used to measure current. Do not measure voltage by clamping the conductor being measured.
- Professional Technical Support Team - If you have any questions about the product, feel free to contact us! Our California-based support team will respond within 24 hours.

Having been an automotive tech in a past life, specializing in electrical, I can confidently say this is plenty good for basic automotive electrical troubleshooting needs. And it's sturdy enough for that work. I was quickly able to diagnose a suspected problem with an RV DC-DC converter that had me guessing between a faulty breaker and/or the charger itself. It appears it will do fine for my DIY exploits on 120VAC for the house and appliances. Here's is something the manufacturer can improve upon, IMHO. Documentation. I've never used a clamp meter for working on AC circuits until now, but I assumed that like DC, only one conductor can be tested at a time. That turned out to be true for this device. Or in other words, do not clamp this directly onto, say, the cord of a household appliance and expect to get results. You will not because opposing polarity conductors that close to each other nullify the magnetic fields of each other. I noticed they do not call this out in their manual [they do in the product description here, though]. I believe that may introduce some confusion. Also, I'm assuming "hard wired" current readings intensionally do not work. They do not on mine and the manual isn't clear regarding this. However, I didn't buy it for that. I primarily need inductive current readings, so the other features I see as a bonus. Especially the near field/live circuit testing for AC work as my previous tester went missing. I'm not sure it's "Fluke" accurate, but it's been more than good enough where applicable. I do use a Fluke on my bench on "little stuff", where high accuracy is a need. I don't think this is truly intended for ma/mv use. Or in other words, it may be capable of that resolution, but it would not be my first pick as a daily driver for working on "little stuff". Seems plenty good so far to toss in a tool bag/box for automotive and house needs. It's a nice, rugged little meter at a low price.
