Smart Digital Multimeter

Wow. I've been on a quest to find the most reliable, best bang form your buck, high quality auto range multimeter with a few functions that anyone wanting to get into the world of electronics. My requirements Autorange 4000 counts minimum for better precision Be able to measure dc voltage Be able to measure dc current less than 10A. Device should have manual mode as well. Be able to measure resistance in ohms Continuity test with lights or beep It can be dropped, it doesn't feel to bulky and needs to fit in my pocket with leads. Accuracy need to be withing +/- .05 volts and acceptable resistance of leads less than .5 ohm Tests will be performed against calibrated craftsman, everstart, lomvum, multimeters for accuracy. All of those multimeters i have and are being used for various diy projects. This unit is less than 10$ and is perfect for all those requirements and it just works. No fuss, no extra stuff, no features I don't need and the price is amazing. Still not sure it's 6000 counts like it says but I don't have a way to tesr this. It's ability for 4000 counts thought is awesome. Because it's a high count device it can take a moment for the auto range detection to flip to the right measurement so I personally prefer to manually switch to the thing I want to measure and the measure away.

This is an update after using the meter for 2 weeks. - A fantastic bargain, hard to believe, a well-designed meter. I bought two more. - Automaatic mode works great. It can detect resistance to 20 megohms. Over 20 megs, use the manual resistance selection. Automatic figures out what it is connected to, and displays voltage or current, AC or DC, and resistance. Neat. - I am using lithium batteries. They work great, and will NEVER leak and destroy a nice meter. They have an initial voltage of about 1.8 volts and will remain up for at least 10 years at idle. Negatives: - Resistance display is to 1 ohm, not to 0.1 ohms as stated in the instruction manual. - Does not have the usual diode test function that shows a diode's forward voltage. - Reading a diode in AUTOMATIC mode shows a different resistance in both directions. But select MANUAL ohms, and it shows conduction in only one direction (as expected). So when conneccting actoss a diode, always use MANUAL resistance mode so that it will read infinity in the reverse direction, and a resistance in the forward direction (when the RED lead is on the ANODE side). The resistance value shown has no meaning, but it serves to show the direction of the diode. - The 'DIODE' icon at the top of the display NEVER comes on (except momentarily during power-up). So what is it there for? Maybe it is for a future DIODE mode (that is not available in AUTOMATIC mode) ? - The 20-inch leads are a bit shorter than I like. If longer, they would not fit as easily in the box.

This is an easy to use meter that works fine. It has a voltage detector for checking 'hot' line voltages non-contact. Nice.

I can go from resistance (continuity check) to DC voltage check without doing anything but moving the probes (again, no innuendo). No need to select anything. After years with a click-click-click tester this is like, unbelievable.

Simple to use! One review was critical of complicated directions, just skip over the technical stuff! A GREAT meter for only $10!

I compared this Hanmatek meter to a Fluke 189 meter. Excellent accuracy even with a square wave. It really is a true rms reading meter. The DM20 is very well built , far better than I expected for the price. Operation is simple with the automatic selection mode. The only missing feature is a diode check. Test results: Input. Fluke. Hanmatek 5vdc. 5.031 5.05 30vdc. 29.992. 30.07 5vac 60Hz. 4.997. 5.021 Line voltage. 119.72. 120.6 5v rms sq wave 4.995 4.953 300 ohm. 294. 295 100K ohm. 98.6K. 98.5K

The instruction manual is so technical I can't understand how to use the meter. I have found a Utube video, but haven't had time to look at it yet so i hope it will use more nontechnical terms to explain what lead goes where for the different functions.

Needed a simple meter for continuity and basic 12v diagnosis and it works perfectly. Not excessive option on dial so it's quick to set to use . Does feel a little light and cheap but it extremely inexpensive . I think it's a value for the price and it works well. I'm thinking about getting a few more.

Erkennt "Alles" automatisch und ist handlich, lässt sich aufstellen und sogar aufhängen (s. Foto). Für mich als Hobby Bastler perfekt. Preis/Leistung stimmt und das Gerät gibt mir ein Gefühl, nichts "falsch" zu machen, da es automatisch erkennt, was ich mache. + Kabel sind nicht steif + Handlich + praktische Halterung für beide Prüfer + Erkennt Leitung im Wände etc. + Dank auto/off, keine leere Batterien. - Ohne Tasche. (aber die Aufbewahrung im original Karton finde ich sogar besse, da dieser sich seitlich aufklappen lässt)

Works great easy to use and accurate.

Genial como polímero de bolsillo. Uso profesionalmente a diario un medidor Fluke, alguna vez que se olvida cogerlo, no tengo con que trabajar y buscaba un polímero de bolsillo que pudiera guardar en la furgoneta en caso de apuro. Conozco medidores chinos que cuando los metes en un enchufe empieza a variar la medición y no sabes lo que mide o si está bien el aparato. Este te da una medición examen exacta y correcta, y es muy fácil de usar ya que tiene medicación automática, en resistencia continuidad funciona perfecto también. También puede funcionar como detector de tensión sin contacto, por la parte superior, lo he probado y funciona al acercarlo a enchufes y cajas de registro. Se puede iluminar la pantalla para ver medicaciones en lugares oscuros y tiene un pequeño led para iluminar la medición. Muy contento con las prestaciones y calidad

Très efficace et rapide à utiliser. Le mode de calibrage automatique est sympa.

Es buen producto de fácil uso para quien no le entienda a la electrónica solo poner las puntas a lo que vas a medir y listo ya sea corriente directa o alterna súper práctico
