AstroAI Digital Multimeter TRMS 4000 Counts(Auto Ranging and Manual) | Volt Meter with Backlit LCD; Voltage Tester Measures Current, Temperature, Frequency, Continuity; Tests Resistance, Diodes

I have many years under my belt as an electronics engineer diagnosing component level faults on pcb's and I am used to much more expensive DVM's (digital voltmeters) so I feel qualified to review this one. First off the price is really cheap so I wasn't expecting much but I was pleasantly surprised that is wasn't as bad as I was expecting it to be. It's quite light in the hand but feels well made, mostly hard plastic with a hard rubberised outer case which should negate some drops and bangs. The bale stand on the back is flimsy and will probly break if flexed the wrong way too much so just be gentle with it and it should be okay. The screw which holds the battery cover / stand on goes in to a brass insert and not just screwed in to plastic so thats nice. The screen is easy to read at different angles and has nice large numbers on and while isn't the quickest at updating its okay considering the price. The test leads are fine and work okay for general use I cant comment on battery life as I have not had it long, this review is first impressions. I have attached some pictures where I tested the accuracy of this DVM, the DMM Check Plus was Calibrated recently and I checked it with one of my Flukes just before testing the AstroAI DT132A and the Fluke read spot on for each of the tests. The tests performed were AC & DV volts , AC & DC mA and Resistance, you can see the results for yourself.

My eyesight is not as good as it used to be and I was getting frustrated trying to accurately read my old fashioned analogue needle type meter so it was time to get one with a big digital display. My needs were fairly basic…..checking the status of various rechargeable batteries I have for various things and also being able to do some basic continuity testing when fault finding (I just want a nice loud beep if all is good). This unit perfectly meets my needs. It feels perfectly good quality in my hand, and the display and controls are easy to use. When checking battery voltage, it’s first setting is autorange and the screen looks like it’s showing lots of spurious data before touching the probes, but just a few quick prods of the range button will shift the decimal point to something more useful and stable. It only takes 2 seconds to do this and I thought it was worth sharing as a tip. The thermocouple on my first unit was damaged but a quick email to AstroAI got a replacement sent to me. For this price point I was truly impressed how good their customer service was. I’ve used fancier brand meters (Fluke) and sure, this does not feel like it would be quite as tough as them if used hard day in day out, but the quality is certainly good enough for home use. Great value.

Works well. Handy tool for checking electrical connections. Everything and more your average diy’er could possibly need.

The AstroAI Digital Multimeter, TRMS 4000 Counts Volt Meter is a product I would seriously recommend. As multimeters go, this little unit has all the unique features of most of its “High End” rivals and at a price which is very affordable. Aesthetically well designed and very easy to use. The “Auto” range feature is exceptional which means no fumbling about guessing what setting you should use on any of its functions, it just does it all automatically for you. It’s accurate, it’s fast, it’s a mid range product at high end spec. The accompanying booklet would be better served if it was larger ie: same as the package box, and a carry case would have been a nice addition to store the meter and it’s accompanying leads. (Maybe AstroAI will read this review and send me one for free) fingers crossed !!

Those who know what these do will understand, this is a great multimeter that I was lucky to purchase during Amazon prime so around £16, but at £20 this is great value. It has all the features that other multimeter have BUT with the added sound which for continuity checks is really handy as you don't have to look at the display all the time. But is super easy to read and works really well, really happy with this as it will make repaires a lot easier.

This appears to be good value meter, well made and easy to use as other reviews have stated. However there are a couple of issues. The leads in my meter were not very good. I actually ruined one of the leads completely when trying to remove cover to use extended point. It is Very difficult to remove the covers. As a result I had to spend money on a new set. The second minor issue for me is the beep on selector changes and button press. I am sure it will not be an issue for many but it can slightly annoying. The support from AstroAI is excellent, prompt and friendly.

I already have other multimeters, which frankly feel better built, but for all their functions and accuracy none happen to have a max/min function. I wanted to leave a meter in series with my car battery for a day to see if any modules were waking up when they shouldn't be and causing it to lose charge. Once the car has gone to sleep I can press the Max button and when I come back at the end of the day it'll show the highest value. (Hint - not mentioned in the user manual but I found you can disable Auto Power Off by holding down Select whilst turning it on. It'll beep 5 times and then power up without APO displayed on the screen. It'll then beep 5 times every 15 minutes as a reminder rather than turning itself off. APO is restored next time you turn it on) If you need Max/Min capture then this DT132A is an absolute bargain. If you don't need that then there are other cheap meters around that feel a bit more robust. I'd suggest Uni-T, having had a couple of their meters for a few years now. Their UT890C is currently the same price here on Amazon.

I bought this to replace my previous Maplin autoranging meter after that died when the batteries leaked. The autoranging makes using this easy, and i particularly like that DC Volts and AC Volts are selected by different positions on the dial - so i don't need an additional 'function' button press to select the right one - which is an issue on many other multimeters. The continuity function works well - quick to react and easy to hear. I also like that this model includes a temperature probe - a useful feature for checking fridges, freezers, and ovens. The display is big and clear, but as previous reviewers have pointed out - the illumination only stays on for a few seconds which might be an issue if you need to use it in dimly lit areas for a prolonged period (my last meter was just the same in this respect). On the other hand, if it stayed on much longer i guess the batteries wouldn't last long. The unit itself is a conveniently compact size compared to other meters, but with a good sized display, making it pleasant to handle. Subjectively, i think this meter takes slightly longer to display a reading than my last one, but it also seems to settle and give a stable reading better. Another advantage compared to other meters is that it can measure up to 500ma on the fused input before having to move the lead to the 10A input. Many other meters can only handle 200ma. The leads seem OK - not too delicate. But i'll keep my old ones as spares just in case. Pleased with the purchase so far - it cost half what the last meter did - and i purchased that 16 years ago!

Nu kunde jag mäta lite startkondensatorer. Hur bra som helst. Blir bra i min verktygslåda för el arbete.
