    I bought this tester over a year ago and am now just writing a review. I carry it in my breast pocket at work and use it just about every day, even though I carry two different Fluke units in my tool bag. However, I did modify it. A use 2 magnets (very flat and strong from an expired hard drive), one inside and one opposite outside of the cover to hold it to a vertical surface. I stuck a dozen small post-it notes inside the cover. I also use a soft rubber wristband (the type that are given out for fund raisers) around it when closed to give drag or friction to keep it from sliding out of my pocket when bending over. If it ever breaks or stops working, I will probably buy another one because it was so inexpensive.

    I hadn't noticed this feature when I ordered it, but when it came I was pleasantly surprised to find out that it was a 'True RMS' meter. This means that when you test voltages that are not a true sine wave, you will still get an accurate reading. Meters that are not 'True sine wave' will read 10 or more percent lower when reading voltages from inverters (Modified sine wave) which are commonly the small devices that convert 12 volt DC to 120 volt AC. Another nice feature was the 'capacitor' testing function. Any one who diagnoses problems with motors and compressors will find that invaluable. Because of its small size, i wouldn't use this to try to measure any great amount of voltage, but for normal 120/208-220/460-480, I would feel comfortable using it.

    I am really happy with this little multimeter. This will be a great small DMM to carry on a motorcycle for trail diagnostics if it's ever necessary. Vehicles are full of electronics and they have high reliability in their relatively mild environment. Dirt bike electronics are getting more and more sophisticated and they are subject to much harsher environments. Their reliability is compromised as they vibrate, age, get wet, corrode, etc... I'll report back if I ever really need this meter on the road or trail. In the meantime, I suspect this will see some service around the house! My regular DMM does not have some of the features of this little meter. The only thing really missing for my purposes is a current setting. Knowing how the current measurement typically works, I can imagine it being difficult to integrate into such a small meter -at least in a high enough capacity to be useful. My only real disappointment with the meter is the battery access. Requiring a small philips screwdriver to access the batteries might be a non-issue if the two AAA batteries last a long time, but I would still prefer not to need the extra fastener.

    I once forgot to bring my regular-sized DMM to a job... That happened to be the time I shocked myself (particularly painful) on a circuit that was supposed to be dead. I then started looking for a DMM I could carry around with me all the time. The DMM's actual dimensions are about 5in x 3in x 3/4in. This was larger than what I had gathered from the description. However, it fits great in my back pocket. Clearly, this is not a substitute for good measuring equipment. It does not have an ammeter function, and I haven't tested its accuracy. In conclusion, I would gladly pay $16 to avoid future shocks by testing circuits with this device that I can carry with me all the time.

    Als Digitalmultimeter würde ich das Gerät nicht bezeichnen, man kann damit nämlich keine Stromstärken messen. Ich glaube, bei der kompakten und vor allem flachen Bauweise wird das jenseits von ein paar A auch nicht möglich sein: Schon allein die Messkabel mit den entsprechenden Steckverbindungen, der Bereichswahlschalter und der Shunt (den es hier erst gar nicht gibt) würden entsprechend klobiger ausfallen müssen. Als "Erstgerät" kann ich das daher sicher nicht empfehlen! Leider gibt es keine genauere Produktbeschreibung, wenn Sie aber die zweite Produktabbildung von oben vergrößern, sehen Sie auf der Innenseite des Deckels die näheren Spezifikationen. Die Bedienungsanleitung ist übrigens ausschließlich auf Polnisch, aber wer so ein Gerät verwendet, braucht ohnehin keine, bzw. weiß bei den Spezifikationen, was gemeint ist. Gerade wegen der Kompaktheit habe ich das Gerät gekauft, es ist etwas klobiger als ein Smartphone, ich kann es überall "dabeihaben". Meine Einsatzgebiete sind Amateurfunk, Raspberry Pi und Co. "Mobil" brauche ich immer wieder ein Voltmeter, Durchgangsprüfer, Ohmmeter, und Faradmeter. Gerade für Microcontroller ist der Frequenzmesser und das duty cycle-meter sehr brauchbar. Die V(AC) sind TRMS, was bei einem Gerät in dieser Klasse selten ist. Unabhängig davon verwende ich einen USB-Stick mit V/A-Anzeige, der wie ein Labornetzteil Spannung und Strom zugleich anzeigt, und der einfach zwischen USB-Buchse des Netzteils und dem USB-Kabel des Verbrauchers zwischengesteckt wird. Der hat ein paar € weniger gekostet, und deckt eigentlich fast alles ab, was bei mir an "Strommessungen" mobil so anfällt. Wie schon gesagt, als "Erstgerät" kann ich das nicht empfehlen, so richtig Schaltungen durchmessen kann man damit nicht, es fehlt auch ein Induktivitätsmesser. Aber die ganze Litanei, die einem praktisch so unterkommt, lässt sich damit hervorragend überprüfen: Wieviel "Saft" hat der Akku noch? Sicherheitshalber: Führt der Pin jetzt wirklich 3,3 V aus der Microcontrollerwelt, oder 5 V aus der Arduino-Welt? Ist der High-Pegel hoch genug zum Durchschalten der nächsten Stufe? Kalte Lötstelle? Farbringe nur mit Lupe und in interessanten Farben, oder die Kapazitätsbeschriftung überhaupt nicht lesbar? Vielleicht noch ein SMD, wo durchmessen schneller geht, als Lupe und Nachschlagen? Elko "geschossen"? "Spinnt" der Servo, oder die Software, die das PWM-Signal liefert? Müsste sich die PLL bei der Eingangsfrequenz "einhängen"? Sollte ich bei +/- 10% Bauteiletoleranz lieber nachmessen, wenn das kritisch sein könnte? Usw. usf... Nun die Kleinigkeiten: Das Herumstöpseln zwischen den Eingangsbuchsen entfällt, weil es keine gibt - siehe oben, man klappt einen kleinen Deckel auf und nimmt die Prüfspitzen aus dem Fach, das war's. Die Prüfspitzen haben übrigens eine Rille, in die man Messdraht o.ä. "rumwickeln" könnte. Das Batteriefach ist mit einer Schraube gesichert, dafür braucht man das entsprechende Werkzeug und etwas Geduld. Sowas gefällt mir eher nicht. Ich habe keine geeichte Spannungsquelle, daher habe ich ein paar Widerstände nachgemessen. "Hausnummern" sind dabei nicht aufgetreten. So als "Schweizermesser" ist das Gerät für mich ideal. Ich glaube, durch den Verzicht auf das Amperemeter hat man da ein anderweitig sehr potentes "Handy" gebaut, und der Preis ist schwer in Ordnung. Einen Stern habe ich abgezogen wegen der polnischen Betriebsanleitung und der lästigen Schraube, ohne die das an sich zum Schieben gedacht Batteriefach nicht wirklich hält. Das wäre beides zu vermeiden gewesen.

    Great for the person who needs a device with them at all times that's not a pain to carry around. Approx. 5"x3"x3/4" pretty much fits anywhere. Cable length is just over 12", but remember they are internally wired to the back of the meter. Unit requires 2 AAA batteries. (supplied) The operators manual, as mentioned by others, is in Chinese. At the time of this writing, no English version was available to download from website as noted by others. One consolation is that inside the cover is an English label describing the various range limits. It also notes its an "Auto Range" and "Auto Power Off" device. I like the the nice clear 5/8" numeral display.

    オートレンジですので「電圧がこれぐらいかな?」とか言うレンジ選択の手間がかかりません。 電圧測定で直流と交流の切り替えがあるのでそのままダイヤルを合わせるだけで測定開始できるので便利です。 テスターによっては電圧モードにした後ボタンを押して直流と交流を切り替えるものがあり、いちいち画面を見て確認しないといけないのが結構面倒です。 電流を測ることは出来ませんがその代わりテスターを壊すことがほぼ無いというメリットがあります。 電流測定モードのままでバッテリーの電圧を計ろうとしてテスターを壊すことがほとんど。(私もやらかした。爆) 他の方も書かれていましたが蓋がグルっと回って本体の後ろにピッタリくっつくようになっていますが蓋の固定がないのでプラプラします。 ここは改善してほしいところ。 電池は単4電池2本です。 電池は付属していませんから別途入手する必要があります。とは言え100円ショップでもコンビニでもどこでも手に入る電池ですから入手に困ることはありませんね。 電池の交換時は#1のプラスドライバーが必要です。 テスターリードが少々細いのと直付けですから手荒な扱いは厳禁です。 他のコンパクトタイプ全てに言えますからこのテスターだけの欠点ではありません。 小さな工夫ですが関心したのは蓋に細長い穴が空いています。 ダイヤルを左側のオフに合わせないとダイヤルが蓋にあたって蓋が閉まらないようになっています。 スイッチの切り忘れ防止機能ですね。 価格も安いですし、ちょっとした測定には便利ですのでおすすめです。

    I didn't expect much of a multimeter that cost under $15 and had all the features packed into the little package like this one did, but it works well. Im not an electrician by any stretch but I assume if you are you're not buying this thing. I saw people say it feels cheap but I disagree. If you think you can be rough with a $15 compact multimeter perhaps there is a different problem. I really appreciate the auto range because I don't know which setting to choose if I'm not working on a car or a house.

    プローブを測定の度に差し込まなくて良く、片付ける時もバラバラにならないので便利です。 ただ、本体に収納する際、少し入れにくいのは仕方ないかな・・・ それから、スイッチを切り替えるたびに、ピッって音が鳴るのですが、これが思った以上に大きな音なので、少し耳障りです。 気が向いたらふたを開けてシールでも貼れば解決すると思いますが、もっと小さな音でもよかったと思います。 あと、フタは上にヒンジがついていて、後ろにフリップして開けるのですが、後ろでプラプラするのがちょっといまいちな感じがします。 まあ、でも、フタがどこかに行ってしまうこともないので、それはそれでいいのだと思いますが、できればプローブ部分だけを閉めるフタになっていればよかったと思いました。

    形状は小型で胸ポケットに入り良いのですが、リード線と測定棒をいちいちケースにしまうのが私のような無精者には大変な作業です。そういう意味では大型のものにすべきだったと思います。 このテスターを選んだ理由は周波数の測定が10MHzまで出来るというのに魅かれました。確かに周波数のカウントは仕様通りできました。1KHzの解像度は0.1Hzです。 私が誤解をしていたのかもしれませんが、ACレンジの周波数特性も10MHzまで延びているのかと勝手に思い購入しましたが、これが大違いで1KHzを過ぎると急激に指示値が低下します。1KHzまでは大丈夫です。せめて100KHzまでFlatならばオーディオの測定に役立つと思ったのですがどうやら虫が良すぎたようです。 でも1KHzであれば1mVでも測定できますので私の今までのテスターよりは格段の進歩です。 その他キャパシター、DC/AC電圧/ダイオード測定など問題なく測定できました。

    安価ですが、しっかりした作りです。 残念なのが、 中国から発送されるので届くまでに約2週間かかりました。 急ぎで必要な方は注意して下さい。 また、クッション封筒で送られてきましたが、 中の箱が潰れていました。 幸い破損はしていませんでしたが、 神経質な方は控えた方が良いかも知れません。

    It works, for $16 one can't ask for much more. It DOES NOT MEASURE CURRENT, if that's not obvious from the description and lack of current socket. The plastic holders for the probes are crappy but whatever.

    よく考えられた設計。 蓋を占めるには測定モードをオフの位置にしないと閉まらない。 単4電池2本で使用可能なため、電池切れの際は困ることはないだろう。 リード線も収納できるし、ストラップも付いているのは驚いた。 計測精度はまだわからないが、三和のテスターと比べてみて遜色なければ文句なし。 ただ、全部の側を比較すると三和のテスターよりは大きくコンパクトさに欠けるが・・・・ この機能性を考えれば逆にこれぐらいの方が目立ち、扱いやすいと思う。

    This is a nice meter. I use VOMs on a regular basis for my job. This one works quite well and I like that it comes in its own integral hard case. It also will stand up on your bench or table and is quite accurate as well. I like it! Only about $13!

    This may not be the most accurate voltmeter, but I was tired of never having *ANY* voltmeter when I needed it. This thing travels well, and so it can be in the bottom of the computer bag, or the glove box of the car and will be there when I need it. Considering getting a second one for the wife's car. Has all of the basic functions so that you can quickly check continuity (audible continuity meter), check to see if a wall plug is bad (AC 110 or 220), or even a quick battery check.

    This is a quick and easy meter to use. A handy meter you can throw in a bag or trunk or glove box to be able to troubleshot or measure at those unexpected times.
