Review on Advanced Digital Auto Ranging Multimeter (AC/DC) by UNI-T - True RMS, Multitester by Andres Black

Revainrating 5 out of 5

In my opinion the best multimeter for the price.

This is a fantastic instrument in every way; especially for the price. I spent a lot of time and research selecting this pup. I bought a replacement Fluke 289 that I had for many years (a gauge that still costs at least 7x the price of this gauge). Over the years I've used Fluke, I've come to love its accuracy and smoothness, but I hate what I see as the price gouging that comes with the gold standard in multimeters. When my fluke started failing, I decided to dive into the Chinese cloning market because I believed that after 7 years of technological advances, someone could build a decent gauge for under $60! This meter did not disappoint me at all. Physical and electrical build quality is good. Physically it is about 75% larger than the heavily overloaded Fluke (Fluke is designed for everyday use in the field). Electrically (in terms of safety when working with high voltage) I'd say it's also 75% compared to my old fluke (I'm talking about contacts inside the case if you need to open [don't do that unless because, you know what do you' do], delete the disconnect on the motherboard, etc.). If you're doing very high voltage work (above standard line current), the Fluke 289 will withstand a "catastrophic failure" better than this meter, but I've used this meter with line current (110/120V) quite comfortably. Because of the rather tricky high voltage frequency measurement, I even did a little grid violation test (don't do that). It squeaked like a stuck pig (warning signal) but didn't even shut down or lock out. When you understand the power and energy in your humble outlet, you'll understand why it made a powerful impression on me and gave me confidence that I could do almost any low-voltage DC job compared to mains power. I've been using this meter almost every day for several hours a day since I got it about a month ago and I've fallen in love with it. I tested it with 1-2A current analysis at 12V with no problems. Current tests in the low mA range were also carried out without any problems. I like the fact that the meter is safety paranoid and gives quick current alarms in the less than 500mA range as the low current terminals are only protected to 1A, saving many novice users from a blown fuse and even experienced users from inattention. I'm comparing this meter to a $500 meter and I can honestly say, unless you're a field engineer working for a utility that drops your meter, bumps into things and abuses it, there's no reason to worry. no more being ripped off by the big boy on the block. Also, for the price of this gauge, you can afford to blow up one and buy another at the price of the cheapest Fluke available (which is NOT the quality of the 289, which is a "professional" gauge). I hope this review helps one or two people. I was very embarrassed to spit out a big brand's "yellow lemonade" for this relatively unknown brand, but I hope the manufacturer continues with their good work because they have a convincing combination of price and quality. Accuracy is the same as the Fluke, refresh rate is slightly slower, and the wires are plastic instead of silicone. I intentionally used plastic leads instead of Fluke's silicone leads which I was only supposed to use to test the device 'as is' and while they are less convenient than silicone leads I can live with them and I will keep my silicone leads for as long as possible keep it because I don't need it. them in a vertical cabinet full of cables and other entanglement hazards, not in my lab work station where I can conveniently move cables out of the way. I hope that this baby will serve me for a long time. If you experiment and research enough, you will end up subjecting your meter to electrical abuse. Paying more than the cost of a good oscilloscope just for a multimeter is ridiculous these days unless you're in a very specific field. I will update this review sometime in the future after more adventures in Mr. Om's playground. I hope I will be as satisfied as today. PS: I get along well with my equipment. Any abuse my equipment is subjected to is dutiful due to the nature of my job. If you are new to meters, take the time to learn, learn, and experiment safely with low voltages and currents before proceeding. READ OWNER'S MANUAL and follow DUTY CYCLE WARNINGS! If you want to "dive straight into the water," buy a $10 meter and expect it to blow up :-) Electronics are a great thing, but electricity is relentless. And you can't buy a new life!
