HANMATEK Handheld Digital Oscilloscope 100Mhz Bandwidth with 2 Channels HO102 3.5"TFT Mini Oscilloscope, 2 in 1 Oscilloscope and Multimeter, Backlit Screen, Auto-Calibration Function, Memory Function

Well made and works as intended. Quality product. Fast updates on the screen, great resolution, easy to read, and much better than similar offerings.

The device is slightly larger than a multimeter, and noticeably heavier. It has an internal battery which is charged via USB; the charger, cord, probes, and carrying case are all included, no external components are needed to begin using the oscilloscope. Compared to a bench oscilloscope, the start up time is fast - about 1 second. Practically all of the features that one would commonly use on an oscilloscope are available and work as expected: AC and DC coupling (for trigger as well), 1x and 10x probe, XY mode, measurements, cursors, reference waveform, saving waveform or screenshot to file, bandwidth limit, and even a built-in 1 KHz signal for probe compensation. The layout of the buttons is convenient and functions are easy to find. The DMM mode runs independent of the oscilloscope and has relay switching for the V and mV ranges. The device appears well built and the battery lasts a long time (after 30 minutes powered on the indicator appears at about 80 %).

I'm very happy with this instrument. The scope works well. The meter is ok. It is not a true RMS voltmeter but then it doesn't purport to be. One thing i really like is its stability on the desktop. I can actually just push the buttons without holding it with my other hand. It doesn't tip over easily. I would buy it again.

This review is based on several weeks of use, so no long term conclusions.The good parts.I needed a portable "floating", as in isolated ground, scope for poking around on the mains side of power supplies. HO52 fits the bill. It seems to do the advertised 50MHz and has the multimeter side isolated from scope side, as in, multimeter ground is not connected to scope ground. Probe BNC connectors are shrouded and 1KHZ contacts have rubber cover. So from visible safety perspective it looks good.The interface (buttons) is laid out reasonably well, so it is possible to operate with one hand - I can hold the unit in my left and reach all the buttons with my thumb.Battery life seems to be around 5 hours, but I did not try to run continuously for 5 hours.Multimeter readings seem to be within reason from Brymen BM869, so no complaints. Although multimeter is not my reason for buying O52.Not so great parts.Autoset function works fine down to 20mV-18mV signal. As long as you do not expect benchtop performance out of the portable unit, it is OK. Frequency measurement starts working at around the same signal level - 20mV~18mV. So this could be better.Masurements are very basic, so are the triggers. No channel math.I did not find a way to adjust vertical or horizontal settings smoothly (uncal in Tektronix speak, Vernier in Rigol's) - it is always discrete jumps. So if you are trying to measure rise time, there is a bit guessing game where to place your cursors (for example at 10% and 90% of PK-PK).Conclusion.Would I buy it again for a portable scope with a "floating" ground? Yes, no doubt.Would I buy it as a starter scope if I did not have a benchtop unit already? No, not really. It would be better to save and buy a 1GS/s 100MHz desktop unit with better sensitivity and features. HO52 is not a replacement for benchtop unit.

This oscilloscope is straightforward and easy to use, making it perfect for beginners. Its clear display and intuitive controls make waveform analysis a breeze. Overall, a reliable choice for basic electronic testing needs.

It's a good multimeter and scope for the price. I like how I only need 1 piece of equipment and that it's portable. The screen is high resolution and easy to see in direct light or bright rooms. My only grip is that the controls can be a little clunky and not very convenient. The instruction manual is not not very good and filled with grammatical errors. Once you have it calibrated it's a good scope and multimeter though. Just make sure to charge it.

I love this thing. It's easy to use, once you understand the features. It works great. I diagnosed issues with a few automotive speedometer signals and a crank sensor signal. It works great as a multimeter too, but the included leads suck. I bought some Fluke leads and this became my go-to multimeter. The issue is, 2 months later the battery finally got low, and the thing won't charge. Tried multiple chargers. It says it's charging, but even after hours I unplug it and it goes back to saying low battery. Amazon can't help replace it at this point. Just make sure somehow that yours charges when you get it. I'm afraid I'm going to have to just buy another and hope the new one charges.

Have been using Scopes many years....Since this scope does not have controls marked as a standard analog scope ,you have to learn what the function buttons mean in correlation with an analog scope. Some things you cannot control, but in the auto mode they are workable. So far I have had a learning curve in regards to Buttons and what they do when and where. So far this Scope seems OK and is compact and well built. I am enjoying the learning cure as far as buttons and functions. For the price this little GEM Comes with hi quality probes and accessories. It's a Great buy and you get quite a bit of power in the little package.Just wish the controls were the same as an analog scope for ease of operation. But like an old dog ..I can learn new tricks.

I fully charged it with the supplied USB power adapter and it declined to 75% power overnight and I've since put about ten minutes on it and it seems to be down to 60% .... I'm not sure about the two hour claims but I'm sure that's why they don't put a running time total on the thing, Like who wants to know how long they have it on for one session???? I'm going to give it a chance though and see how it does after three or more charging cycles. Amazon, be prepared to get this one back or supply me with a unit that remotely gets near the two hour battery life claims.Btw, discovered another issue, the 1x/10x attenuation switch gets stuck when removing the claw and exposing the point of the probe, so you can’t grasp it by the handle and pull, you must grasp it by the stress relief and make sure the handle doesn’t slide back on the core. You can tell if it’s in the wrong position by trying to slide the switch. Update, I am quite pleased with this item and all battery issues have ironed themselves out and as far as the drain of the battery in the off state, it loses only 20% after two weeks sitting. I did a concurrent test and the battery showed a little over three hours of operation with minimal use of the generator or resistance testing.

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.

I do the occasional electronics project at home, and I own a nice Fluke multimeter, but every now and then, an oscilloscope would come in handy. I don't really have the space for a full-size desk scope, so when I saw this little box of tricks, I thought I'd give it a try.It's great! All the functionality of a basic 2-channel digital 'scope - cursors, measurements, adjustable triggering, XY mode - in a box the size of a Fluke, with a decent signal generator and an acceptable multimeter as well. The signal generator will do the usual sines, sawtooths, square and pulses, along with a few other more exotic waveforms. The meter is basic, but has all the functions and ranges you would want for most electronics work.The kit is pretty comprehensive, too - in addition to the meter, you get a carry case, USB cable and UK power adapter, two scope probes, a pair of meter probes and an output cable for the signal generator. The manual is a bit sparse and not that well written - if you already know how to use a scope, you'll be fine, but I wouldn't recommend the manual to a beginner. (If you already know how to use a scope, a meter and a sig gen, you won't need the manual anyway - the controls are all pretty logical.) It all feels of decent enough quality - it's not a Fluke ScopeMeter, but then it's less than a tenth of the price!It is powered by a rechargeable (via USB-C) battery, which is good for 4-6 hours.Cracking bit of kit, and fantastic value for money.

Ich bin kein Elektriker und benutze das Gerät überwiegend im Bereich von KFZ-Einbauten und Kontrollen. Ich nutze nicht alle Funktionen die das Gerät bereitstellt. Es wurde wegen der Funktion Oszillisator zur Messung einer Sinuswelle am Spannungswandler angeschafft. Nach umfangreicher Recherche zu dem Thema konnte ich das Gerät dafür sinnvoll mobil einsetzen. Hier ist sicher auch der große Vorteil dieses Gerätes, welches nicht an einen festen Spannungsquelle betrieben werden muss (.. wie die sicher besseren aber "ortsfesten" großen Geräte).Die Bedienungsanleitung ist für die umfangreichen Funktionen für mein empfinden nicht ausreichend ... es sei denn man ist sehr versiert oder gar ein Fachmann. Das Gerät selbst scheint als Oszi gut zu funktionieren und ist gerade im mobilen Bereich sehr handlich und nützlich. Ich halte es für preiswert, obwohl es eine größere Investition ist. Besonders angenehm habe ich auch die Spannungsmessung empfunden. Nicht zu vergleichen mit €10-20,- Geräten die man hier auch kaufen kann. Der Einschaltknopf ist zumindest so weit geschützt dass ein unabsichtiges Einschalten bisher nicht vorgekommen ist.Die Tasche ist besonders im Hinblick auf das Zubehör (2 Einheiten für Oszillisationsmessung) verbesserungswürdig. Nach meiner Ansicht etwas zu klein und mit zu wenig geeigneten Fächern für die Zubehörteile. Das Gerät selbst finde ich gut. Bisher war das Gerät noch nicht sehr häufig im Einsatz (.. privater gelegentlicher Gebrauch).

Embalaje austero aunque correcto. El equipamiento adicional como cables y sondas, excelente. Se ve una buena construcción y acabados, aunque las partes plásticas podrían ser mejores. El osciloscopio tiene toda la funcionalidad básica que se espera de este instrumento.En cuanto a la parte PC, la aplicación para revisar la información guardada y la comunicación vía USB están aceptablemente desarrolladas y funcionan sin problema.La parte de multimetro funciona también con precisión y confiabilidad.Una buena compra. Ahora solo falta que tenga una buena durabilidad y proporcione años de servicio.
