AstroAI Digital Multimeter - Accurate TRMS 4000 Counts Voltage, Resistance & More - Auto-Ranging & Fast Measurements

Zag: was using a very basic one and wanted to upgrade, this multimeter has given me everything I have needed for testing electronics and has been amazing.

M. H.: Kann alles was man braucht. Bestimmt gibt es robustere Geräte für einen höheren Preis (selbst Astroi bietet solche Produkte an).
Dennoch ist es für den täglichen Hobby/Privatgebrauch absolut geeignet.

TOMO: □私のような素人が、趣味で使用する分には充分な性能です。多くの方が言われるように、説明書は最低です。最初に乾電池の装填方法等がかかれていなければ不自然ですし、老眼には全く読めない文字のサイズです。本体プラスチックが柔らかめに感じるのは気のせいでしょうか。落とした時の耐久性に問題なければよいですが、ロータリースイッチも押すと凹みます。勿論戻ってきますが、これも衝撃を和らげるきのうというのあれば、気が利いています。プロなら国産を選択するのかもしれませんが、価格が高騰している今日、3000円前後であれば購入しやすいのはありがたいです。欲を言えば、とりあえず使用できる保護ケースを付けていただければなおよかったです。

Gerry: 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.

Marco B.: 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

RD_Prime: 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.

cleo s.: goede kwaliteit en juistheid van de metingen, voor deze prijs niet te kloppen. grootte toestel is ook goed niet te klein of te groot. ik ben zeer tevevreden met mijn aankoop

esther: this meter comes with 3 aaa batteries, rubber shell, thermocouple, and test leads and a single sheet instruction manual
the meter is 4000 count, auto ranging, "True rms", has backlight, hold, min/max and relative functionality.

DC VOLTS: (400 mV - 600 v). tested accuracy was way within the 0.8% spec for all ranges. more near 0.1% for most middle of the range measurements (very happy with that).
it beeps at you when you go over 600v.

AC VOLTS: (1v - 600v). tested accuracy was also good (usually 0.1% innacuracy) but is only accurate between 10hz - 2khz. outside of that range it becomes unusable. likewise waveforms with a high crest factor struggle. a 1 vrms squarewave at 100hz has an inaccuracy of about 1% whereas a 1Vrms 100hz sinewave's reading exactly matches the 1 Vrms input. (very nice)

FREQUENCY: (1Hz - 40MHz) wonderfully accurate ( im very happy :) ).
works down to like 0.001 Vrms which is impressive and doesn't seem to discriminate between waveforms. super hand little frequency counter.
(I didn't test the duty cycle but it is probably good enough and is nice to have)

Resistance (400 ohms - 45 Mohms )
accuracy is good but not as good...

Barry Wolt: 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...
