Review: Good low cost DVM - 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. Review: Easy to use, works well. - 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! ## Features - WIDE RANGE of tests for AC/DC Voltage, AC/DC Current, Resistance, Continuity, Capacitance, Frequency and Temperature; Tests Diodes - PROFESSIONAL LEVEL features include Auto-Ranging capability, and True RMS for measuring both AC Current and Voltage - EASE OF USE: Convenient features like Data Hold, Large LCD Backlit Screen, Kickstand, and Low Battery Indicator make taking and recording measurements easier than ever before - IDEAL FOR COMMERCIAL settings where it can handle the demands of a long workday, from the durable exterior to the wide range of heavy-duty capabilities - SAFETY FIRST: Two integrated fuses rated at F500mA/600V and F10A/600V; Explosion-proof ceramic fuses provide maximum safety; The fuses can protect the multimeter effectively; Overload protection on all ranges. 3 Year Warranty provided by AstroAI ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07FDBW1PT | | Best Sellers Rank | 19,327 in DIY & Tools ( See Top 100 in DIY & Tools ) 26 in Multi Testers | | Brand | AstroAI | | Colour | Red | | Compatible Devices | Electrical Devices, Appliances, Electronics and Vehicles | | Country Of Origin | China | | Customer Reviews | 4.6 out of 5 stars 8,845 Reviews | | Global Trade Identification Number | 00700713359227 | | Included Components | 1 | | Item Dimensions | 15.5 x 10.8 x 3.9 centimetres | | Item Type Name | AstroAI Digital Multimeter, TRMS 4000 Counts Volt Meter Manual and Auto Ranging; Measures Voltage Tester, Current, Resistance, Continuity, Frequency; Tests Diodes, Temperature, Red | | Item Weight | 145 Grams | | Item dimensions L x W x H | 15.5 x 10.8 x 3.9 centimetres | | Item weight | 145 Grams | | Manufacturer | AstroAI | | Manufacturer Part Number | 132A | | Measurement Type | Multimeter | | Model Number | ASIMT132A | | Number of Items | 1 | | Number of Packs | 1 | | Power Source | Battery Powered | | Power source | Battery Powered | | Specification Met | CE, RoHS, UL | | Style | Industrial | | Style Name | Industrial | | UPC | 700713359227 | | Unit Count | 1.0 count | | Upper Temperature Rating | 40 Degrees Celsius | ## Product Details - **Brand:** AstroAI - **Colour:** Red - **Item weight:** 145 Grams - **Power source:** Battery Powered - **Style:** Industrial ## Images ![AstroAI Digital Multimeter TRMS 4000 Counts(Auto Ranging and Manual) - Image 1](https://m.media-amazon.com/images/I/71cRET3JHkL.jpg) ![AstroAI Digital Multimeter TRMS 4000 Counts(Auto Ranging and Manual) - Image 2](https://m.media-amazon.com/images/I/71Uw6R9zKFL.jpg) ![AstroAI Digital Multimeter TRMS 4000 Counts(Auto Ranging and Manual) - Image 3](https://m.media-amazon.com/images/I/7163sMLyLdL.jpg) ![AstroAI Digital Multimeter TRMS 4000 Counts(Auto Ranging and Manual) - Image 4](https://m.media-amazon.com/images/I/7197-tW-erL.jpg) ![AstroAI Digital Multimeter TRMS 4000 Counts(Auto Ranging and Manual) - Image 5](https://m.media-amazon.com/images/I/81rKoaJk1pL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Is it possible that the leads supplied with the meter don't plug into the front of the unit? Mine seem too large in diameter to push into the ports.** A: There’s a cap on the leads that you need to pull off. Once you remove the covering they fit. I had this same initial issue. Cheers. **Q: Do this multimeter comes with a case, if not do anyone where can i buy one** A: no it doesn't come with a case **Q: are there test leads with aligator clips available for this meter? if so where?** A: Test leads with alagator clips do not come with the meter, but a set with alagator clips are available on Amazon that should work. I hope this helps. **Q: Will this meter measure frequencies on a sensor with specs between .114hz and .152hz?** A: Hello Customer, Thanks for your concern, yes, this meter can read frequencies between .114hz and .152hz.
