    • Easy to use meter for folks who have no spark in their lives and those that do.
Size: DT132A Multimeter
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. ... show more

    • Excellent meter for hobbyest and students
Size: DT132A Multimeter
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. ... show more

    • Great for automotive diagnostic, leads need attention
Size: DT132A Multimeter
Great for mA parasitic draw testing, I tested the leads for continuity but the readings were all over. 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 ... show more

    • Ridiculous value for the money
Size: DT132A Multimeter
Initial impressions are good. I have owned a half dozen or so meters in the under $50 category and this is by far the nicest and most feature packed. The little things that others have complained about like the beeping and the quality of the leads don't bother me. In fact these are probably the best set of leads I have ever gotten, in terms of length and stiffness/plastic-y feeling. I like the sleeves on the tips as well. They fit secure and help prevent accidental bridging in tight spaces. Accuracy seems good enough for me. I am not necessarily doing high precision work with this unit. It will mostly be for testing batteries and repairing/troubleshooting home and automotive electrical. I appreciate that this unit measures temperature and I have already used that function. I haven't had that feature before. I also like knowing it will test capacitors, diodes, and does true RMS and Duty Cycle. My only wish is that it had the magnet leash like the 6000 model, but that's no deal breaker. I am very pleased with this unit. ... show more

Size: DT132A Multimeter
Good meter except for the fact that the backlight times out after about 10 seconds. I contacted customer service and they recommended a replacement meter that would not time out the backlight. DM6000AR is the model.
