What is the low range on ammeter. Will it read 100 uAmps?

  • The instruction sheet appears to show two different models. One measures current, the other does not. The switch on this meter points to "off" rather than "mA" at the 2:30 position, so this meter does NOT measure current.

    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。

    この価格にしては使えます。 今持っている日置のテスターと精度を比べてみましたが、若干の違いこそありますが、そんなものは他のどのテスターでもある範囲の誤差。 作業内容にもよりますが、さほど精度を気にしないような作業であれば、全く問題ありません。 抵抗値の測定に時間が掛かります(4秒くらい)。 あとは耐久性があるかどうかですが、追ってコメントしたいと思います。

    販売店も迅速丁寧で、すぐに届きました 商品は思いのほか、ケースが丈夫で コードも中にときちんと収まり コード切れの心配が無い感じです 他社のテスターと比較しても遜色無い機能 電池も単4で購入が他社のボタン電池より楽 その分本体が少し大きいが、胸ポケットに ちゃんと入るサイズで問題無し 今後の使用で耐久性が問われるが 値段的に、そこだけが今後次第ですね

    以下の点が気にいってます。 ・ボタン電池や特殊な電圧の電池でなく単4で使用出来る。 ・プローブを収納して保管できる。 ・電源をOFFにしないとカバーが閉まらない。(切り忘れ防止) ・オートレンジで測定前に悩まなくてもいい。 ・コンパクトで持ち運びも保管も便利 精度はどれくらいなのか分かりませんが車の整備や 充電池のチェック・家庭用の電気工作程度には十分だと思います。

    For the price this thing cant be beat - has all the basic VOM settings - and is accurate - use this for vehicle work and anywhere I would not take a more expensive VOM, its not a fluke but for the price - would recommend.

    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!
