Handheld 2 in 1 Oscilloscope and Multimeter 50Mhz Bandwidth with 2 Channels HO52 3.5"TFT, Backlit Screen, Auto-Calibration Function, Memory Function

A brilliant piece of kit. Charges in minutes from my 120W phone charger. All connections work as expected. Great value for money.

There’s not much really to explain. It’s an all in one, 2-Ch scope with a combined Digital Multimeter. Other reviews have stated it’s not a surgically accurate piece of kit but for my basic needs (testing automotive waveforms and power/gnd in the field) it’s about as good as you’ll get on this price point.It’s fairly compact, light weight and extremely clear enough to use but the scope controls can feel a little clunky. Once you’re used to it, setting triggers and changing time scales becomes second nature.My only gripes are the BNC Probes aren’t the best (I use a different set of test leads) and battery life could be a little better but at least it’s rechargeable.

It is very accurate in measurement when used as a multimeter. The oscilloscope is very practical, especially for me that little space in my laboratory.It works well and I recommend it.However, there are 2 points on which I think it could be improved:1. Sometimes the triggering loses the wave and I have to redo the auto button to resume it2. The battery does not last long. I recommend using a powerful charger because it could happen that the batteries are completely discharged and the oscilloscope turns on partially with dark video. In fact, these had made me think it was broken. But then I calmly reloaded it and everything was back to the way it was before.I also have to thank the supplier who was quick to reply when I needed them.Recommended.

Great hobby and educational scope. Used on a few projects now and it is great. Ideal when helping kids with physics homework. Battery life on a full charge seems a tad short so don’t leave on if not using. Easy to use. Great value for money and does not take up valuable space.

Normally I don't do reviews, but I was absolutely blown away with this. I originally had a old Rapid Electronics multimeter that sadly died after 10+ years of use.I saw this, and decided to get it, as wanted to gamble with oscilloscopes, due to not having one.I didn't realise when I bought it, but found out through just looking through it when it arrived, you're able to test resistance of resistors and the capacitance of capacitors. I was blown away with this. No more having to deal with the colour bands of resistors, no more having to deal with arduino software to test capacitors. It's all there, and all accurate within of course an acceptable margin.I did swop the multimeter leads out to my other ones, as the ones that come are fixed, so I was unable to swap the end out for SMD probe, alligator clips, and wire grabbing probe. But that's not entirely a problem.Pro's- Features I mentioned above- Packaged nicely- Little carrying case- Fully charged when arrived (In my case)Con's- The multimeter leads it comes with are pretty basic.Can't wait to use this more 🥰😊

After messing up the language settings (reverted back to Chinese!) and getting them back to English (don't ask me how!) I managed to start using this Oscilloscope/Meter. Comes in a soft bag with all the required leads and a comprehensive manual. Buttons are soft rubber but very tactile and firm in their operation, the screen is clear and the brightness is adjustable. There are more settings to change than you could shake a stick at so I am not going to go into a full technical review here, suffice to say this is a good, quality, robust oscilloscope/Meter which is excellent value for money. I am looking forward to making full use of this in my job and hobbies.

After two extended sessions across two days, despite the manual being a bit sparse (e.g. "XY mode option: Choose to turn XY mode on or off"), I feel like I've got a handle on this device now. My main use for it was to see if I can make a decent rectifier and voltage regulator for a bicycle dynamo that produces AC, pictured, and evaluate different components for it. It'll also be really valuable for another project where I want to work with really short LED light bursts, where I'll be able to set single-shot triggers to examine what's going on during the micro- and nanoseconds surrounding the event.Probing various stages of the rectifier, and being able to monitor graphically what difference it makes to add filtering capacitors, and vary their sizes, or watch exactly how much of an effect a bleeder resister has across a capacitor, is quite satisfying, and really gives a better feel for what's going on than a multimeter can. I'm only starting out in electrical engineering, and I get the sense I'm going to have to have pretty special use cases and get far more advanced before I could imagine needing any more features than this device provides, plus this little device is far less intimidating (and costly) than a traditional desktop oscilloscope.Some other notes:I had to check out a few other oscilloscope videos online where there was a particular feature that the manual didn't explain well enough for me.I expected it to run off some AA batteries, but it turns out it's got a rechargeable battery inside, that can be replaced easily enough if needed.Leaving the multimeter probes connected whilst probing with the oscilloscope, there was some extra noise, so make sure to unplug the multimeter probes when not in use.I wish there were a dedicated zoom in / out button per axis, I find it unintuitive to use the arrow buttons of the axis perpendicular to the mode I'm using instead. If you zoom out far enough on the time axis, you can get a handy scrolling view of the voltage, somewhat like a seismograph.Something that wasn't clear to me despite being in the title: having two channels means you can monitor two signals at once, or use one channel's signal to trigger a capture for the other channel.I'd suggest, while using the reference square wave after calibrating the probes, try out all the buttons and function buttons in various modes, safe in the knowledge that you can factory reset to get back to square one if you need to.

UPDATE:I've had a chance to use this thing in anger but when I get back to put it on charge... poof.DEAD.This is clearly an issue with these devices and I should have noted that earlier (as others have) but I hoped I wouldn't get one that did. But sure enough... Deader than a dead thing.Which is a shame because it's a useful and usable meter and a smashing little scope. Not great for bench work but handy for something that you can just pick up and use.So, with some regret it's going back.---------------As a dual-purpose instrument, this is very good value for money. I'm concerned that there maybe issues with the batteries but that could be a supplier thing so we'll see.The meter is fast and the display is clear. Absolute Accuracy is something I'll leave for more expensive instruments that are calibrated by hand but this is good enough for the sector it serves.Other people have complained about the rather "dense" control panel but I made short work of it simply by pushing buttons. I'll probably come back when I have more time and give some basic notes on what I missed. A lot of functions are context sensitive, so it's important to follow the menus or back out until you're at default.The two channel scope is OK but the full-screen response time is of the order of a few 10ths of a second. This has to do with the speed the screen can refresh at, not the ADCs and this shouldn't matter for most use cases but it might be an issue for some people. It looks a lot faster because it only does partial screen refreshes so that it can keep up with the sampler.I note that it also has an XY mode which, while I haven't tried, wasn't something I'd expected. This can produce lissajous figures when fed sine/cosine waves from a signal generator which are pretty but not a lot of use - however this can also be pressed into service as an "octopus". Which is my next project after my "current" one (bit of an electronics Dad joke there). But really, an octopus can be amazingly useful in diagnosing some surprisingly tricky faults by not just helping identify unknown parts, but can peer inside some components in ways that are very difficult or impractical with a multimeter.

I like it, i've not used oscilloscopes that much, so i'm pretty new to them, however I was able to do everything I wanted rather easily.The only thing I don't like is that it is pretty hard to zoom in at look at a specific part of the waveform, as you move around in large steps both in scale and in position

Value for money. However, the function generator related option could have beenvery clearly indicated. It seems I did not select this option since the page clearly hinted that it is available - and it is not available.

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.

J'ai longtemps hésité sur le choix d'un oscilloscope “pas trop cher” avant de m'arrêter sur celui-ci, et je crois que j'ai fait un excellent choix : il tient dans la main mais il a tout d'un grand !C'est un véritable oscilloscope double trace avec une bande passante de 50 MHz, et non pas un “multimètre évolué qui fait vaguement oscillo”.Il est précis, agréable à utiliser, facile à prendre en main et on trouve assez vite toutes les fonctionnalités désirables dans les menus. Je ne trouve vraiment rien à redire. L'écran est également très lisible.La fonction multimètre apporte un plus appréciable, elle est bien conçue et simple d'utilisation, bien que ce ne soit pas la destination principale de cet appareil.Pour reprendre une critique que j'ai vue dans un autre commentaire, et la seule que je puisse faire : la housse fournie gagnerait à être un peu plus protectrice et surtout un peu plus grande, dans l'état on peut y ranger les cordons du multimètre et le câble USB plus le chargeur, mais les deux sondes du scope n'y entrent définitivement pas. Dommage !Mais bon quand sur ce genre de produit on n'a que la housse à critiquer ;)Dommage aussi que le modèle intégrant un générateur de signaux soit considérablement plus cher, mais bah je préfère un bon scope sans générateur de signaux, plutôt qu'un mauvais avec.

Me ah servido para lo que necesito, Solo la batería dura poco
