HANMATEK 3 in 1 Handheld Oscilloscope Multimeter with 2 Channels HO52S 3.5"TFT Oscilloscop, 50Mhz Waveform Generator Multimeter Backlit Screen, Auto-Calibration Function, Memory Function, Multi Tester

I have waited to review this. I'll firstly address the battery issue. Mine's been absolutely fine. I've had it for ten months and it's been idle for the last six. Just fired it up and it's showing about 90% full, still charges and everything. I say that because other reviewers have had issues with battery life. I think if you need a scope, this is a great place to start. I purchased the 50Mhz with generator. The broad specs on this are very acceptable for general use, 50Mhz will do most things, the 125MSa/s sample rate is good enough for my use. And the frequency generator is an incredibly useful feature. Not to mention the multimeter, very handy. If you don't own a scope, and you're curious. I would highly recommend the one I bought. I like the frequency generator for fault finding. I've mainly used this on vintage guitar amps. But I have also used it to diagnose injector signal issues in cars. Obviously just two channels, so you can only compare two cylinders at a time. I have a four channel bench top oscilloscope, sampling at the standard 1GSa/s, but I haven't had cause to use it since getting this. It's so portable, does basic DMM functions too and is just good enough for most things I need. I guess my use is diagnostics and fault finding. Fantastic value for money. If you're on the fence, I would recommend you just go for it. Wish we had kit like this fifteen years ago!

Does what it should.

Very good quality, much easier to carry out on a field visit than all the other kit you'd have to put in your rucksack to do what this can do all in one. Docked a star because if you're NOT on a field visit and are at home instead, a bigger desktop scope is much easier to use, with all the handy rotary controls etc - there's nothing they can do that you can't do with this Hanmatek (well, I do have one with an 8-line logic analyser and protocol sniffer, which can intercept UART serial ports, I2C, SPI etc and this can't do that, but is a feature only of interest in digital electronics anyway), just the fewer controls here make doing everything via the d-pad a faff. But it CAN do them, and is a perfectly good scope, just twiddling a dial on a device with a much bigger screen is so much easier than incessant menus. Image shows just the sig gen function from the Hanmatek below being read by an xminilab tiny single board scope above, even more awkward to use with just four buttons, but ironically has the most functionality of the three scopes I have, despite the least ease-of-use.

OWON社のHDS200シリーズと迷っていたのですが、アマゾンアウトレットで格安で販売されていたのでこちらの商品を購入してみました。 諸先輩方のレビューを見ると、操作性やマニュアルに難があるような書き込みが多数あったので心配してましたが、実際にオシロモードを操作してみると、仕事で日常的に据え置きオシロを使っている自分にとっては、操作方法は違えどプローブの校正方法以外はマニュアル無しでも直感的に操作できましたので、UIとしては何ら問題ありません。 テスターモードでの電圧や抵抗値の測定レスポンスに関しても、十分許容範囲で何らストレスは感じません。 FGもちゃんと機能します。 日本語取説やアプリ等は同梱されたチラシのリンク先にちゃんとファイルが存在していましたので、こちらも問題なくダウンロードできました。（2023/5/18現在） 但し、ダウンロードしたPCアプリについては、インストーラーがエラーで起動しないので使えませんでしたが、アプリの取説や付属ドライバから推測するには、OWONのHDS200シリーズのアプリと同じ物だと思われます。 この辺については、確認次第再度リポートしたいと思います。 総合的には非常に満足できる商品ですので、あとは耐久性だけですね。 ★PCソフトウェアの追加情報（2023/5/19) 動作しないインストーラーについて、販売元のHanmatekにアマゾン経由で確認した所、その日のうちに メールでインストーラの新たなリンク先が送られてきました。 新たなリンク先のインストーラーの方はキチンとインストールできました！！ サポートには全く期待していなかっただけに、予想外の迅速な対応にちょっとびっくりしました（笑） トータルで見るとよい買いもでした。 ★購入後3か月経過の再レビュー（2023/8/30) 使い込んで感想として、評価の芳しくないボタン操作のUIも慣れてしまえば全く問題なしで、逆に精度の高いオシロ、DMM、ファンクションジェネレータが外出先でもこれ一台で賄えるので大変重宝しています。 ■波形の精度・・・10MHzまでの矩形波であれば据え置き型の100MHzのオシロと比較しても遜色なし。 Sin波は20MHzでも問題なし。 ■DMM・・レスポンスが悪いとの書き込みがありますが、amazonの格安DMMよりはるかにレスポンスが良いので実用上問題ありません。 ■バッテリーも2時間以上持つので実用上十分。 良い買い物でした。

Ho acquistato questo strumento gia' essendo dotato di una discreta strumentazione per un uso fuori dal laboratorio visto che e' alimentato a batteria e nelle misurazioni con massa flottante in quanto una sonda differenziale costa uno sproposito. A volte uso i due canali mettendoli in ADD ma questo e' decisamente piu' comodo. La dimensione del display e' buona, il trigger funziona in maniera adeguata al costo dell'apparecchio, la calibrazione mi sembra entro i limiti, ho scoperto poi con sorpresa che funziona anche come capacimetro, ovviamente non per capacita' dell'ordine dei picofarad me nell'uso comune molto utile. La dotazione dello strumento e' ottima, sonde e puntali buoni, c'e' anche il software per collegarlo al pc (cosa che difficilmente faro' comunque il fatto che ci sia e' sinonimo di serieta'). Il firmware a bordo rende intuitive tutte le funzioni, in ultima analisi sono molto soddisfatto dell'acquisto anche in funzione del suo costo decisamente contenuto. L'unica cosa che non mi e' piaciuta per niente e' la staffa posteriore che permette allo strumento di stare in piedi, la trovo troppo gracilina e inadeguata all'aspetto complessivo, lo strumento infatti si presenta molto solido.

begeistert, einfache Handhabung, gute Darstellung, gute Qualität und Design. Für einfache Messungen völlig ausreichend.

Good as multimeter, oscilloscope and signal generator.

Es un osciloscopio en toda regla y un generador con tabla de ondas todo en uno. Es un poco incomodo de manejar desde su teclado pero para medidas rapidas es mas comodo que un osciloscopio de banco.
