The AstroAI AM33D Multimeter is designed to safely and accurately troubleshoot a variety of automotive and household electrical problems. It's easy and safe to operate and features many different functions for measuring current, voltage, and resistance, as well as continuity, transistor, and diode testing, which is both for automotive and household uses. Use this multimeter for: household outlets, fuses, wiring, general-purpose batteries, vehicle battery and charging system, automotive circuits and more.
The grip of the multimeter is around the edge of the entire multimeter and a kickstand on the back so you don't have to be holding the entire time when you want to use it. It can also be used to diagnose, assemble, and repair circuitry and wiring. Other features include a low battery indicator, continuity buzzer, and overload protection.
The Hold Button can be useful when it's for more precise measurements. For example if measuring a sensor you might want to make a note that the meter reads 2.984 V and it's more convenient than trying to remember the value while you write it down on a piece of paper or enter the value into a spreadsheet etc.

I bought this multimeter for some DIY work on my car's external dashcam battery circuit. The multimeter worked great in checking the diode direction, DC voltage/current, and circuit continuity to ensure my DIY modification work as intended.

The AstroAI DMM lacks the uniqueness of its tyre inflator and is reminiscent of older multi-meter (DMM) designs that are based upon a simple, single-dial design plus a button, or two. This is not a criticism but rather an endorsement that simplicity often results in fault-free operation and zero learning time. The AstroAI DMM is typical of this basic design of which there are a great many available. I am pleased to see the lack of dedicated sockets for testing transistors which hark back to multi-meter designs (analogue MMs) decades old.
Selection of a suitable DMM was made difficult by the number of choices available and I was guided by the range of measurement options, simplicity of operation and above all cost. The Amazon illustrations fail to give an impression of the look-and-feel, weight and size of the DMM and I gambled upon the AstroAI DMM being small, pocketable and lightweight. I was not disappointed. The DMM is fairly thick but once again this is not a criticism. It's bulk makes it easy to handle/grip and to accommodate the large Lithium PP9-sized 9V battery. Many of the newer, slimmer DMMs use button cells. The DMM case is robust and designed to take knocks and drops.
The range of measurements possible with the AstroAI are fairly typical and a good selection to suit most needs. The LCD can be backlit and readings 'held', if required. A pair of probe leads are included. The only thing missing, in my opinion, is a case to hold the DMM and its probe leads. However, this omission is very common and I usually resort to purchasing a strong domestic container of the type usually used to seal and store food.
The price of the AstroAI DMM is another factor but there are many in the same price bracket. Being 'low cost' does not necessarily equate to cheapness (e.g. poor build quality) and the AstroAI is definitely not cheap. I eventually made my decision to buy the AstroAI DMM based upon my previous experience of the their air compressor, being low cost and a superb performer. Recommended.
It is lightweight and very easy to use and the backlight is helpful too.
Not having automatic selection of range is a bit more hassle, but it is worth the trade off for the price and ease of use of this one.
Very pleased so far with no issues
Figured I only needed it for one application so I'd just get something cheap. Waste of money though as it only ever shows the value '1'. Whatever setting you use, whatever you connect it to. Just feels like a flimsy kids toy or something.
Turns out, there's several more times since that I could have used one of these multimeters. So don't cheap out like I did. Spend a bit more and make an investment in something that works and will last. Go for a credible brand.
EDIT: It wasn't just a fuse that blew up. The board has burned too. So in general I wouldn't recommend 10A multimeters as it's too easy to damage them whilst using for a car.
This worked fine and was good at being accurate but stopped working after about 10 minutes. Wouldn't give any reading whatsoever.
Yeah fair enough was only a tenner but I was expecting a wee bit more working time with it than that. Suffice to say! Returned.
Will I be purchasing it again? Nah don't think so.
Je l'aurais préféré plus petit , (comme celui mis en photo à côté) mais je n'avais pas fait attention aux dimensions.
