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

This is a good unit but I left mine sit for too long with the batteries that came with the unit. They disintegrated and destroyed the unit. My own fault so warning is to change out the batteries to something more reliable.

I bought this because I saw my favorite YT auto blogger use it. Ivan of Pine Hollow Utopia Diagnostics is probably the smartest auto diagnostician on You Tube. It hasn't disappointed me.

I've had the AstroAI DT132A multimeter for just a few of days so far and can report some impressions. First, it is astonishing the features packed into this DMM: auto/manual ranging, min/max, relative measurement, hold function, temperature, true RMS and 4000 counts. All for $23. We owe all that to the single DreamTech DMM chip inside. The same chip is used for many brands of meters. I have not opened the case but from viewing a teardown video, the innards are sparse indeed with few other components but it does look to have some input protection components. For my use the 4000 count display is more than adequate. In many years of electronic work only a few times have I needed more than the four digits of precision that this meter provides. The single sheet manual with microscopic font size is adequate but barely. Note that the 145x70x35mm dimensions it gives for the meter are incorrect. If you're shopping for a case, the actual dimensions are: 155x75x35mm. Many, if not most, multimeters have separate banana jacks for current measurement vs. the voltage, capacitance, etc. combo input jack. This meter does have a separate input jack for the 10A current measurement but it uses the combo input jack for uA and mA current ranges. The good: convenient to not have to unplug and re-plug for a current measurement. The bad: if the probes are connected to measure a voltage, say with alligator clips, and you even momentarily switch the rotary switch to the uA or mA setting IT COULD FRY THE METER. At best it would blow the 500mA fuse, at worst it could burn the circuit board. The instruction sheet does state: THE MANUAL ROTARY SWITCH SHOULD BE PLACED IN THE CORRECT POSITION BEFORE MEASUREMENT AND SHOULD NOT BE MOVED DURING MEASUREMENT TO PREVENT DAMAGE TO THE METER. Some reviewers have complained about the beeping at every setting change. I like it because some SELECT button settings don't apply to some rotary switch positions so it will not beep for those. The beep provides some feedback that the setting will be applied. It does have the red outer moulding of soft-ish plastic, but it's only 0.1" thick so it will provide only minimal protection in a drop. The kick stand is flimsy and easily bendable. One surprise is that it came with the three AAA batteries installed--not just placed in the box. As other reviewers have stated, the backlight stays on for only 15 seconds then the button must be long-pressed to re-light. If you need to use the meter in low-light environment you'll get tired of that. If there is some cryptic button sequence that changes that timing, I'd like to hear about it. Overall, it's a remarkable feature-rich meter at a bargain price but with flimsy construction. I'll subtract one star for the thin rubber overmould and backlight timing.

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.
