Limited tool to use as oscilloscope. Very narrow threshold (1Mhz). Nothing different from others as a multimeter, no key or special features as a multimeter so not really worth it to me instead of the multimeters I already have so no significant addition. I am returning this to Banggood if everything goes ok. It was shipped fast and vendor is good, no complaints.

I made some measurements with it. Easy to use, it comes as a replacement/complement to my old multimeter that works with a 9V battery. I took it mostly to have fun with the oscilloscope. In short it's nice, but it's really useful:), we'll see to the use. That said on the photos, we can see that a connected plug sends parasite.

j'ai réalisé quelques mesures avec. Facile d'utilisation, il vient en remplacement/complément de mon vieux multimètre qui fonctionne avec une pile de 9V. Je l'ai surtout pris pour m'amuser avec l'oscilloscope. Bref c'est sympa, mais est ce vraiment utile :), on verra à l'usage. cela dit sur les photos, on voit bien qu'une prise connectée envoie du parasite.

Really pleased with this. Got it a month before the worst case estimate of Banggood. Checked it out just this evening. Scope mode seems to be pretty accurate at least visually with the small screen. And, the screen visibility is very easy on the eyes, at least indoors, which is where I'll be using it. Bandwidth seems OK, although I haven't measured it or checked the waveform risetime. My reference here is the old Tektronics 545 scope, which was 5 MHz BW, I believe. The rated input impedance is 10 Megs. Don't know if I believe that, but seems reasonable. I checked the loading on a geiger counter that I built. It's not high enough impedance to keep from screwing up the tube voltage, but that's not a surprise either. When I built the circuit I had to make a special probe to be able to see the tube waveform and voltage; that's still going to be true. One shortcoming of the scope functionality is that it has no AC trigger. That means that to get a stable waveform, you have to go into the trigger and adjust the DC trigger level. That works fine, but of course it's only good for the waveform you're looking at - a pain to mess with when checking out a circuit with multilevel waveforms. I'd give this product a 5 star but for two reasons. One is the just mentioned lack of AC trigger, the other is that 5 star ratings don't collect viewers usually because they don't convey any useful info. I'm a retired electronics engineer, and circuit designer. While I don't lack for a good scope, this instrument does have a very useful place in my home lab. Simplicity of operation with good insight into the basic waveforms of whatever I want to look at, with the two exceptions - extremely high impedance circuits, which take special stuff to look at anyway, and very low level signals, although it does go down to 30 mV per division.

measurements are sufficient, sine graph x1,x3 and x10 can be set. The case is hard plastic. Powered by 3 aa batteries, color screen can finish fast batteries. overall nice device for this price. The screen reads comfortably in light environment. The only thing I don't like is that they've just had their fuses used. I wish there was a glass fuse.

ölçümleri yeterli, sinus grafik x1,x3 ve x10 ayarlanabiliyor. kasasi sert plastikten. 3 adet aa pil ile çalışıyor, renkli ekran hızlı pil bitirebilir. genel olarak bu fiyata güzel cihaz. aydınlık ortamda ekrani rahat okunuyor. tek beğenmediğim yönü, sigortaları smd kullanilmis. cam sigorta olmasini isterdim.

Small and good multimeter. I tried it in work and compare with bigger tool... This tool is good for basic measurements.. for home.. or for quick check.. for better result you need better tool

Device received quickly. Very easy to use. I translated the oscilloscope part of the notice (photos)

Appareil reçu rapidement. Très simple d'utilisation. J'ai traduit la partie oscilloscope de la notice (photos)

Nice device. Has hidden option to turn off sound. Press and hold F4 while turning on, and you will see "QUITE MODE ON". Really quiet, but "continuity" mode is silent too.
