ZT-702S 2-in-1 Oscilloscope Multimeter with 2.8 Inch IPS Display,9999 Counts, Single Channel 10MHZ Bandwidth,48MSa/s High Real-time Sampling Rate,±400V Input Voltage,Measures Ohm-Volt-Tester

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.

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.

works good bought it for a backup meter.

the seller is honest, excellent product.

Accurate

This was exactly what I need when I want to see a signal waveform for a small electronics project. I charged the battery completely when it arrived, which took some time. I think this is a step some people overlook because it isn't stressed in the directions. When I used the oscilloscope function after charging the unit it worked perfectly.

Pretty difficult to use with no instructions. I had to figure it out by watching several YouTube videos so it took me about an hour. Definitely would recommend a simpler model for most people

I'm loving this multimeter. It's loaded with features and has a large screen.
