Review: Easy to use meter for folks who have no spark in their lives and those that do. - I use it almost every day, to see if I am still alive....kidding. Just a great meter. I use it on the boats (nightmare), electronics, vehicles etc. Had it for years and if you turn it off the batteries will last a long time. This is not like a brain surgery review. Volt Amp meters work, this one is my go to and reasonably priced. I have abused, dropped and whatever you can do to a meter and this keeps doing it's job. This is not an AI review. I am responsible.... Caveat-Don't loose the little screw when you are replacing the batteries...hard to find if you are as old as me. Review: Excellent meter for hobbyest and students - After an intense review of what was available in the digital multi-meter (DMM) product space, I purchased four AstroAI TRMS 4000 meters based on competitive pricing with similar products with similar specifications. These multi-meters were purchased for use by middle and high school students that are participating in the National Science Olympiad program. The features that were required were simple to use, has an easy to read display, is both precise and has acceptable uncertainty, in a physical package that could withstand the abuse/misuse of the students. Most of the digital multi-meters in this same price category, as the TRMS 4000 were NOT auto ranging or too small to have a reasonable size display. The meters with similar features by Fluke, Extech and Amprobe, to name a few, varied in price from ten to twice as expensive. Since I needed four, all of those meters were immediately ruled out. When the TRMS 4000 meter arrived, a quick physical, hands on inspection, revealed a solid design that was well labeled, with an LCD display that was about the same size as my personal hand held Fluke DMM. To test the meters, I used a variety of batteries and precision one-percent resistors to compare the performance of each meter, against my Fluke and against each other. In all cases the TRMS 4000 meters within +/- 4 least significant digits in the three and a half digit mode and +/- 2 least significant digits in the three digit mode. Without doing any real statistical analysis and without true NIST traceable standards, I feel comfortable that these meters were precise with an uncertainty that was within 1% +/- 1 digit in the tested ranges, which seems to correlate well with AstroAI’s stated specification. I should note that the results I obtained with precision resistors was well within the stated specifications. Since these we to be used for Science Olympiad competition, and the general rules prohibit using dangerous voltages, I did not test the AC or higher DC voltage ranges. However seeing the excellent results with low voltage DC and resistance, I would feel comfortable using one of these as troubleshooting tool in a professional capacity on low frequency equipment and appliances. Because TRMS 4000 has a specified input impedance of 10 Meg Ohms, I would not recommend this for use on sensitive instrumentation or high frequency circuits where test input impedances > 100 Meg are recommended and generally required. I would also recommend not using any hand-held multimeter for directly measuring currents in excess of 1 amp even though they may be equipped to do so, external shuts should be used for these types of measurements. In summary, for the price, this is an excellent choice for the serious hobbyist and student. If I had it to do over, I would still purchase these DMMs. ## Features - Digital Multimeter: WIDE RANGE of tests for AC/DC Voltage, AC/DC Current, Resistance, Continuity, Capacitance, Frequency and Temperature; Tests Diodes. - Voltage Tester: PROFESSIONAL LEVEL features include Auto-Ranging capability, and True RMS for measuring both AC Current and Voltage. - Easy to Use: Convenient features like Data Hold, Large LCD Backlit Screen, Kickstand, and Low Battery Indicator make taking and recording measurements easier than ever before. - Capacitance & Resistance Meters: 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. - Additional Tips: This Multimeter is designed to troubleshoot a variety of automotive and household electrical problems safely and accurately.

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.

I lightly sanded the probe surfaces and was able to get good readings. I also have the Astro cm4kor ac dc amp clamp and it's excellent for testing higher currents but I was unable to get good mA readings in series. I originally purchased the Astro DM6000AR but It was unable to read dc mA. I was sent a second one but had the same problem so sent them both back. This DT132A is great. Reads the same as my other good but older meter. I compared both volts and mA and both read the same. Great value for simple usable features. Between this and my amp clamp, I can troubleshoot many common electrical problems on vehicles. Took one star off for the leads needing attention but the are fine once you scuff them up ## Frequently Bought Together - AstroAI Digital Multimeter, TRMS 4000 Counts Volt Meter (Manual and Auto Ranging); Measures Voltage Tester, Current, Resistance, Continuity, Frequency; Tests Diodes, Temperature (Red) - AstroAI 8Pcs Multimeter Test Leads Set with Alligator Clips, Plunger Mini Hooks and Test Probes 1000V 10A CAT III & CAT IV 600V for Fluke, KAIWEETS, INNOVA Multimeter, Voltmeter, Clamp Meter --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/85943582-digital-multimeter-trms-4000-counts-volt-meter-manual-and-auto](https://www.desertcart.id/products/85943582-digital-multimeter-trms-4000-counts-volt-meter-manual-and-auto) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-08*
