Multimeter Tester 10000 Counts TRMS Auto-Ranging Color LCD Screen Digital Volt Meter, Fast Accurately Measures Voltage Current Amp Resistance Continuity Duty-Cycle Capacitance Temperature

I have done a few tests so far. Temperature test: works awesome. Voltage test on AC: works awesome. Amp test: works awesome. Also I love the clear instructions for use for each function, however, I highly don’t recommend just anyone to do some of these tests. This is because if you don’t fully understand the safety concerns outlined in the instruction manual it can be extremely dangerous. The unit is well made and the back light makes it easy to read. The value of the tool is also very reasonable for an apprenticeship when you don’t have a lot of income coming in.

Let me start off by saying that for the price you pay, you're getting a very feature rich multimeter that is as accurate as my company issued Fluke 115 when tested side by side. I work as an Electronics Microsolderer and there are a lot of diagnostics being done in my field that can only be achieved efficiently and properly with a good multimeter. I have a work issued Fluke multimeter that is obviously very good at what it does as Fluke is highly regarded as a premium multimeter brand, so much to my surprise when I tested the AstroAI Smart meter up against the Fluke, I found that the AstroAI meter was just as accurate which is a big plus. However, there were some cons that I'd like to see AstroAI address in a future revision that would make this meter an even better and more well rounded choice so I'll list the pros and cons of the meter in its current state. Pros ________________ - Highly accurate - Cost effective - Easy to read & beautiful display - Large suite of testing functionality - Lightweight & slim (Smartphone sized) - Beginner friendly - Comes with hardshell carrying case Cons ________________ - No kickstand - Test leads insert into the base / bottom - Analog bar serves no real purpose (It updates at the same rate as the digital readout [3 Samples Per/S]) - Measuring Capacitance takes a very long time to get a proper reading (It takes so long that I actually thought the meter was defective for a while when testing it) - No short detected tone / buzzer while using Diode & Resistance modes (This is ultimately what drove me to return this meter as it was a deal breaker for me 😕) - Less than ideal battery life, easily attributed to the large backlit colored display the batteries have to drive - Needing to press the FUNC button to go through the entire list of functions to get to what you need every time (Don't overlook the power and convenience of an analog dial especially if you use a meter and many of its functions a lot; Pro tip - Holding the FUNC button will return you to the beginning of the list AKA SMART mode) - Unable to turn the temperature display on and off even when not using the thermocouples In the end I ultimately returned this multimeter and ended up shelling out the money for a more known brand that functions the way I need it to for my job and personal use. If you're a DIY'er or hobbyist just looking for an accurate and beautiful meter that will ultimately get the job done without breaking the bank and my list of cons doesn't apply to your use case then this multimeter is still a great choice on a budget and that's the reason I'm still giving it 5 stars.

It is very easy to use. The (limited) flashlight is a nice add, and the NCV sensor is a big plus for most intended users. No real downside, couple comments. It is an inexpensive meter, most of the cost is in the display, which is "pretty". The specs aren't quite as good in real life as they are in print, but they are fine for everyday use. On mine: The manual range SETTING DOESN'T WORK, but that is OK because the "autorange" button functions exactly as the manual range is supposed to. Claimed accuracy is decent and real world testing indicates the claims are relatively true. Decent entry meter for a non-demanding electrical hobbyist or a young electrician. The NCV tester probably saves lives. Also, fits in a shirt pocket (leads separate, though). I no longer need a lab quality meter, this covers 99% of what the average field electrician does. Doesn't seem particularly rugged, though I've dropped mine a couple times with no harm. Has a B+ rubberized case, which is a plus. Not much of an instruction book, so it's best for someone who knows the basic features of multimeters. Overall a good value, wouldn't expect it to last 5 years in the field, though it would, with care.

This multimeter is perfect for performing my battery calculations on fire alarm control panel backup batteries. I installed a small lanyard with a magnet at the end to secure the meter to make it hands free while testing with the multimeter leads. Very pleased with the bright LCD screen and the back light for those dim panel locations. The built in led light on the back of the unit helps. All my fellow inspectors keep asking me where I got this. Highly recommended!!

Very nice meter, very accurate, bright display, case, extra set of batteries. It’s all I was hoping for! Very accurate and one additional feature I like is that it stays on for much longer then most meters before the auto shut off engages. My last meter was a different brand and model and it used to shut off too soon. The only thing I wish it had was a kick stand so that it would sit upright. The cables are a little stiff but not bad, they are manageable and they have a rock solid connection. I also really like the fact that the probes have a shielded removable sleeve on them to prevent accidental shorting. And yet if you need a longer exposed tip to get into tight spots, you can remove the sleeve to expose a 3” tip. Highly recommended meter!

OVER MY 50 YEARS IN WORKING WITH ELECTRONICS AND INSTRUMENTS, I'VE USED OVER A DOZEN DIFFERENT MULTIMETERS. THE ACCURACY HAS IMPROVED OVER TIME. FINALLY A COMPANY HAS PRODUCED A METER THAT PUTS ALL THE LATEST TECHNOLOGY, ACCURACY AND EASE OF FUNCTIONALITY TOGETHER...ASTROAI. AND IT IS EXTREMELY AFFORDABLE. I STILL OWN 4 METERS INCLUDING THE B&K PRECISION WHICH COST 4 TIMES MORE, BUT THE ASTROAI IS MY GOTO METER WITH GREATER ACCURACY AND A LITE SCREEN. FURTHERMORE, I AM EXTREMELY IMPRESSED WITH ASTOAI'S CUSTOMER SERVICE. SADLLY MY METER FAILED AFTER 14 MONTHS. I CONTACTED ASTROAI AND RECEIVED A REPLY WITHIN 1 DAY. THEY REQUESTED VERIFICATION OF THE PROBLEM VIA PHOTOS. WITHOUT HASSLE, A NEW METER WAS SEND PRONTO. THIS IS A COMPANY THAT HAS INTERGRITY , AND IS HONORABLE. HAVE FULL CONFIDENCE WITH YOUR PURCHASE. THE 3 YEAR WARRENTY IS REAL AND OUTSTANDING!

I’ve been using this AstroAI multimeter for a few months, and it’s packed with features—True RMS, auto-ranging, NCV, and even temperature measurement. The large color display and built-in flashlight are super helpful. It’s accurate, easy to use, and feels solid. Only downside: the test probes have short tips, which aren’t ideal for small electronics. Also, the smart mode has a slight delay. But overall, for the price, it’s an excellent choice for hobbyists and home users.

Molto comodo e versatile, ottima precisione

I have lost count of how many times i have had to google or youtube how to set up the switches etc on my old multimeter. This one is unbelievable. On auto it just works it out for itself and gives you a reading. You can even put the probes the wrong way round and it still works! It is like a mobile phone with its large screen and is really clear to read. It has a carry case and some other bits that i will eventually get my head around but really is worth every penny.

Me llegó A tiempo buena calidad es automático producto recomendable una observación Amazon y al vendedor o fabricante sería conveniente q ya sea a través de un video corto o en el manual de instrucciones señalen como opta para las personas q no tienen mucho conocimiento en la operación gracias

Natürlich hatte ich gewisse Vorbehalte gegenüber der "Automatik", waren ansonsten nur klassische Multimeter bei mir im Einsatz. Ich konnte jedoch alle Vorbehalte revidieren. Das Multimeter ist handlich und zügig mit der Anzeige der Werte. Auch sind die Werte, verglichen mit anderen Referenzgeräten, sehr genau. Die Anzeige ist hell und sehr gut ablesbar. Etwas gewöhnungsbedürftig ist die Anzeige für die Wechselspannung mit der direkten Frequenzanzeige. Bei der Gleichspannung ist es die Umgebungstemperatur im Geräteumfeld. Für eine exaktere Temperaturmessung liegt ein Messkopf bei. Die beigefügten Masskabel haben am Messgerät abgewinkelte Stecker. Die Messspitzen selbst sind "Spannungsfest und berührungssicher" gestaltet. Leider lassen sich hier keine Klemmen oder ähnliches Zubehör aufstecken. Das ist schade. Es trübt aber nicht die Arbeit mit diesem Gerät. Für Elektroniker ist es ein empfehlenswertes Multimeter.
