702S 2 in 1 Handheld Automotive Oscilloscope Multimeter - 10MHz Bandwidth 48MS/s Sampling Rate,Auto-Ranging 9999 Counts T-RMS Multimeter with Temperature Tester for Electronics Repair Test

I decided to pick this up on the basis of EEVblog's review of it. He was generally rather positive and found few faults in it as a basic portable oscilloscope. It's no Fluke, but it's also not Fluke money. The interface is a bit perplexing sometimes, but you quickly get used to it. It doesn't have every feature you might want, but that's true of most. It's not the most accurate, but look at the price. It's going to have functional limitations. So if you're looking for replacement for a proper benchtop, you're in the wrong place. You really are. But if you're looking for a basic, easily portable oscilloscope that does exactly what it says and meets the safety ratings it claims? This is one truly impressive unit! Sure, it has some minor hiccups. The included battery isn't the greatest, but it's easily replaced. So what it is, is a reasonably accurate oscilloscope with a mediocre multimeter included, and some genuinely useful features like capture and acting as a USB drive. I bought it for light low-mid voltage usage (generally under 48V) as a portable supplement to a benchtop for embedded systems and automotive work. I have a much better multimeter, and I have a benchtop. And I have to say, I personally find it fantastic! It's light enough to be comfortable to hold for long periods, the kickstand works pretty well generally, and the coating isn't so slippery it just falls off when you try to put it somewhere. Does it have faults? None that I would describe as faults as opposed to 'this is what you're paying for.' It does interpolate under the most difficult measurements, sure, but you can clearly see it and the peaks are correct. The interface is a little clunky sometimes. The included signal probe is far from the worst I've seen, but the ground lead is painfully short. (But hey, it's standard BNC. You can replace it.) The multimeter probes are actually quite nice; soft flexible cable and well made grips. I had no problems positioning them on very fine pitch stuff even one-handed. I would have preferred a non-coiled cable for the temperature probe, but it's not as bad as I feared, seems high quality for the price, and is quite accurate. The screen is actually very impressive for the price; extremely responsive, very bright, and very easy to read in poor lighting and direct sunlight. That's a big win for me. The flap over the USB-C and calibration ports is well anchored and thick enough that I'm not worried about it ripping off. The side grips are comfortable and not slippery. The BNC is a little bit of a tight fit, but I didn't have as hard a time with it as Dave. And the receivers for the other probes are well protected and anchored. Another nice touch is that they include a screwdriver to open the case to access the replaceable fuses - which itself is a great feature - as well as the easily replaced 18650 battery. It also came with a full user manual, not just a 2 page 'guide,' which is clearly written and easy to understand. And the icing on the cake? It has upgradable firmware, which Zotek provides and seems to be updating regularly with bug fixes and improvements! The included case isn't terrible either. I keep bringing up price because that's really why you're buying this one, and honestly, the reason why you SHOULD buy this one. Sure, there's cheaper. Sure, there's better. But this one was pretty obviously designed by a company that did their homework. Because it's perfectly situated in both price and function not only for hobbyists, but also for professionals who don't stare at waveforms every day but do have a need on occasion, as well as folks who need a moderately capable oscilloscope they can carry around for daily use they don't have to be terrified of breaking. And for that, it's pretty much perfect.

I'm a car mechanic and every once in a while I need an oscilloscope to check a sensor output or data line. I don't need much accuracy on the scope, I just need to see a waveform. I also, of course, need a decent multimeter. It's really nice to have both things in one handheld battery powered device, although the scope has its own probe, and can't use the multimeter leads. I'm definitely pleased with this thing. It sits in the top drawer of my tool box and gets used almost everyday as a multimeter, and once a week as a scope. Yeah, the UI is a little... odd, but not irritatingly so once you learn it. I'm also really happy that it has a rechargeable battery so I don't have to keep buying 9 volt batteries - those things are expensive! However, battery life is not great. I find myself charging it every other week. But since this is also a scope it tends to stay on for long stretches of diagnosis. That might be why. Still, who doesn't have a usb charging cable (or ten) ready to charge all of their other devices? Would buy again (although I think I want the 2-channel version now).

Bought to tune amps with. Worked great for what i needed. Worth the money and a cool piece of equipment to have around. Did not expect a highend o-scope so it loved up to my expectations.

Amazing multimeter and oscilloscope for the price. I bought this to replace a cheap chineseium meter that I had where the rotary encoder dial had failed because it wasn't gold plated and wore out. This was one of the few meters I could find for a reasonable cost that had a white on black screen. The oscilloscope is a nice bonus, it doesn't have enough bandwidth to be useful on the electronics I regularly work on, but it is useful for diagnosing bad power supplies, it will show how much ripple is on a DC output or if an AC wave form is wonky.

I started a new project that uses pulse width modulation. A simple voltmeter isn’t useful for troubleshooting this sort of circuit, so I plugged in my ancient Beckman Oscope that I bought for $400 at a garage sale 20 years ago. It was dead as a doornail, so I tossed it and looked for a replacement. This little handheld oscope seemed everything I need. It is easy to use, very portable, all at a very reasonable price. I have a few gripes, such as the tip on the grounding clip on the probe is ‘fat’, making it difficult to clip into a small place, plus, the spring is so strong the jaws are really difficult to open. Another gripe is the buttons on the case are poorly designed and one must press them more than 3 mm to close the contact. This is a problem when you are holding the probe precariously with one hand, while trying to do an auto scale with the other. All in all, so far, I’m pretty well pleased with this little unit. Got me through my PWM project very nicely.

I like this Handheld oscilloscope, as a beginner who only need a oscilloscope for minor hobby works this is perfect. On tge top of that this thing is pretty much accurate, hope It will work like that in the long term too.... But if you looking for a professional oscilloscope then i think i wouldn't recommend..... But its portable handy, robust so you might need it for garage works.... The ui is very good, At the end I just want to say If u need a oscilloscope to see waves in you projects then its good, But becuz it has a sampling rate of 48Ms But I really love that it has a multimeter function which is too good to be True.... Very accurate.. But the battery sucks honestly, you have to charge for like 40minutes to 70 minutes to get it full charged... Battery life only stays for 1hr continuously, Update: I had a replacement of this scope meter, cuz the seal was kinda broken at first, I was worried about but nothing was unusual, after getting the replacement it's fully sealed and new, and also got no problems....

It does what it supposed to do but battery backup is less it should have more powerful battery
