Good as multimeter, oscilloscope and signal generator.

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.

Per il prezzo è un buon prodotto. L'ho provato da poco e non ho trovato difetti. Serve un pò di pratica per settare tutte le funzioni che ha nonostante i pochi pulsanti d'uso. Lo schermo è ben visibile. Per il rapporto qualità/prezzo mi sento di consigliarlo.

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!

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.
