Clamp meter
God value for the money just one point every time it's turned on its in dc mode and then one press of the function button will change it to ac

Seems ok
Good multimeter, would have been even better with English printed manual. Now I had to visit some website to get it and print it. Convenient with current measurement in the claw. It differs some from the battery chargers current meter, I wonder which one is correct....

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.
