HEY YOU ABOUT TO POST SOMETHING STUPID:
Yes, I know my hands are large/fat. It's because of a heart condition I suffer from called Congestive Heart Failure. Here's a link to some information about CHF: cle.clinic/2TdS2Ux
One of the symptoms is that it causes fluid retention, mostly in the hands, feet/ankles, and face..

You are a lucky man to get all these meters sent to you. I have the 702s. Really great meter. Hopefully I can afford to get the 2 channel model in a couple of months.
I agree, I don't think any other channel has more meters than Paul. 😊
Interesting signal generator output location. I have a Owon HDS2202S which has 3 BNC on the top, 2 for the dual channel oscilloscope and one for the signal generator. Also has the side port for the probe calibrator and USB-C port. Zoyi does have low prices on their meters. I bought a Zoyi ZT-303 but it failed to measure current properly over 3 amps so I replaced it with ZT-5566SE which passed calibration check at 20 Amps last week.
i love how they display the multimeter like an analog guage
Fun scope!
Presale on the 703 is offering 50% off, coming to $99. I JUST got the 702, after seeing it on your videos, or I would probably order one! That 25k count is pretty nice!
I'm always so tempted to try to start a channel so I'd get sent some of those freebies! LOL
Huge thanks for all you do!
Cool. I bet your delighted with it..
It's SnowNado 🌪️🌀😬
Run, hide in the basement.
Keep warm brother ☮️✌️
100$ for DMM+ 2ch scope+SG, it's certainly not 50MHz bandwidth, but more than enough for analog/audio enthousiasts and tinkerers who don't necessary have lots of space and money.
I just bought the last 703s off Amazon. Just had the 702 delivered yesterday. At about 4:02 you stated it only came with 1 probe instead of two. To each their own I suppose. I intend to use mine for automotive purposes anyhow and already have the powered amp clamps and back probe kits anyhow. But I could see how that could irk some potential buyers who intend to use it for fine electronics
I just got the 702s last week. maybe shoulda waited. I do love the meter though
I got it a couple of months ago and am sad they released it now. But truth is, the 702 is AMAZING still.
A man can never have enough multimeters
@@canadiantrucker9574 true that
Considering it’s $99 right now, sold, I’ll grab one.
your big fan 😊
Thanks!
A lot of reviews like going up to the max, but often don't go down to the minimum. How low can you go before it's putting out rubbish ? Just got my FNIRSI DSO TC3. I bought it to make quick checks and its great for that. This would be same. If you don't have a scope always out and ready to go, just grab this and start using it for quick checks on basic stuff.
Im looking to get a 2 channel scope. I see a nice one that has xy mode and FFT. And a sig-gen too. Not sure if it DMM it's a handheld scope. F-nrinsi make it and Awon or ewon or something.. it's just over €100 and according to buyer reviews it does all its specs 180M .. its the F-nirsi DPOX180H scope and sig-gen. (No meter)
I really hope to see Paul do a video of it.. 😊😊
It’s not handheld, or terribly cheap, but for a mid-range cost I really like my SIGLENT. Had it for about a year now, coupled it with their signal generator and went 4 channel. Yea, I went sort of all out but I’ve had it with cheap low end DSO scopes. Give SIGLENT a look.
Paul, I just saw the 703 for $99.99 on Amazon!
I looked. You must be mistaken. No listing for the 703. 702 yes.
@@randyab9go188 Just picked up 703 on Amazon with two probes for $119 Make sure you check the brand. There is a similar that is not the same as ZOYI. Not sure who or why, but their website does not show them, so no support from the whatever brand.
What his max voltage measure range with osc. probe?
Good question, they are usually 40v on 1x mode and 400v on 10x. But not sure with these😊
Shouldn’t you check actual bandwidth with a x10 probe?
A 1x probe is typically 1MHz bandwidth
Yes if he used a probe and at 1x that definitely would explain why the roll off at low frequencies. It sure hit only the -3db at about 50 MHz not 5 MHz and jitter was bad. 1x probes are not good at high frequencies as they act as a low pass filter because the input capacitance. He sure have had probe at 10x, or use coax 50 ohm termination when testing bandwidth? If he did then that oscilloscope is garbage.
At the website it's $99 50% off til end of month
Who is the better zoyi zt703s or fnirsi 2c23t ?
ZOYI 703s note specifications on the oscilloscope.
@3:24 When did you get pet ducks? ;)
Better there than northern OK. 🤐
Just wondering if the 703S meets the 50 MHz spec?
I doubt it, most of the cheap DSO I have played with start to undershoot at 10-20% of their supposed bandwidth. Anyway, even if they don't go far above 5MHz and would not fit radiohobbyists purposes, it's still 100$ for a 3-in-1 tool that one can use on the field, enough to show small signals for troubleshooting solid state amps, audio equipment, analog electronics, just don't try to use that to measure mains and high voltages without using a proper differential probe and knowledge and that would do the trick. Of couse, it would not compete with a 800$ Siglent/Rigol/... and even less with a x000$ Tektro scope,
Doesn’t seem like it comes close it started rolling off steeply at 5 MHz I would expect roll off to start at 40 MHz and -3db at 50 MHz and suppose to be a 250MS/s ADC but jitter at around 5 MHz which tell be no where near 250MS/s and they are oversampling which is why the jitter.
I tempted to buy this thing to throw it on my level 3ghz signal/pulse generator with a good low loss 50 ohm cable with 50 ohm terminator and on my voltage reference to see what it true performance is. Then tear it down and see the clock output on the ADC and what it real specs. It doesn’t look good for it seeing this video as believe they completely lied on the specs. The 702s was decent for what it advertised but this one performance look bad and is garbage if it is.
You never tested both channels at the same time. Wanted to see if it was better than the last duel channel scope you reviewed as i was a bit disappointed with the last one.. the F-nirsi one. 😢
That wasnt a review, just a look at the newest 3 in 1 from Zotek/Zoyi. Ill put it through it's paces soon.
@@learnelectronics How soon will you put it (703S) through its paces?
Zoom out please. Could basically only see parts of the screen.
As a beginner, I like these little devices, but I wish the manufacturers would market them realistically. They would be better receieved if they weren’t so obviously lying.
Yes, agreed. They never do their specs especially when it comes to Hz measurements.
That disappointing as sure be 50 MHz front end and sure not roll off that low of a frequency. I would expect roll off at about 40 MHz and at around -3db at 50MHz. At 5 MHz start to roll off is an absolute NO. Then notice jitter at 10 MHz start to which tell me the 250 MS/s ADC is not 250 MS/s, or they are over sampling. I may have to buy one to investigate? I do have a level generator use to calibrate oscilloscopes. Then again wondering if you are using a 1x probe? If you are that explains the roll off as most are only good for low frequencies, you need to switch to 10x, or use a good coax 50 ohm cable with termination.
Square wave Performance was pretty bad as well.
10x
@@learnelectronics You set your function generator to 5Vpp, the scope is set to x1 Probe and it shows 4.5Vpp, so you must have set the probe to x1, not x10? This way it is no wonder the scope (or rather the probe) rolls off at some 4MHz. For the bandwidth -3dB measurement, you should see when it drops to 3.5Vpp however.
