Appreciate the review of these. I got the 702. I have noticed the same strange readings when using the scope functions as well. One thing you didnt show or were not aware of, when measuring higher voltages (110 vac and up) the white numbers turn red. Its not a huge issue but the red numbers kind of blend in a bit with the red on the "analog" display, makes it a little harder to see. Battery life on mine has been all over the place as well. I got mine for about $45 on temu, cant beat that.

@KissAnalog 4 месяца назад

Thanks for the great feedback! Yes I realized I forgot to show the high voltage warning (red LEDs) and I wish I had. It is a nice feature, but if the display is hard to see - then maybe they could have changed the background too?

@ssalient 4 месяца назад

I probably gonna get a 703 for portable work. It seems more than sufficient for what I want to do with it and its a really handy all-in-one solution. I think, if they keep the support up for firmwares and such, Zotek really has a winner on their hands with this one!

@KissAnalog 4 месяца назад

I agree. The price of these and what they do is crazy good value.

@terrym1065 4 месяца назад

Eddie👍👍 I think there's an option for two scope probes for the 703s during purchase. You maybe could use the 702s probe along with the 703s probe for two channel use on the 703s scope. Nice and thorough showing the differences between the two scope meters, thanks. You've run out of room on that bench😮 You're gonna need a bigger boat😉

@Peter-rt3tu 4 месяца назад

When checking for probe setting, AC coupling etc., you always looked at the channel 2 settings, but the generator was connected to channel 1. Maybe this is why the readings looked a bit odd. However, when autosetting, the scope should show the correct values, e.g. 1V instead of 1.4V.

@KissAnalog 4 месяца назад

Thanks! I did turn off channel 2 at one point so I was just testing channel 1. Did I make a mistake somewhere?

I have the 702 although bside branded. The larger screen and extra channel would be nice. Im still happy with the 702 as it suits my rather primitive needs. Good little scopes.

@KissAnalog 4 месяца назад

Thanks for your feedback! I was happy with the screen size on the 702 as well. It is only when you see them side by side that the 703 looks so much bigger.

@wizzardofwizzards 4 месяца назад

Hi Eddie, so the Zoyi seems like a bargain for the cost. However, I got a FNIRSI DPOX180H handheld dual channel digital oscilloscope at 180MHz for a few dollars more at the AliExpress 11/11 sale. While it seems clear there are several trade-offs, and the manufacturer's specifications are a matter of interpretation, I was wondering if you are familiar with the DPOX180H and if so, what your take on it is?

@KissAnalog 4 месяца назад

Thanks for asking. I'd love to run a comparison side by side with the ZOYI. The FNIRSI looks great but is around $170 where the ZOYI is only about $75. For the price of the ZOYI - it is pretty impressive.

50% trigger sets the trigger at 50% of the current waveform (like "trigger auto level"). Siglent oscilloscopes have this function by pressing the trigger level adjustment knob.

@disuye 4 месяца назад

Dumb question - I want to get an automotive range (200-500A) current clamp to measure starter motor draw / injectors etc..., which clamp should I buy for the ZT703S? Can the ZT703S record an oscilloscope trace from the multimeter banana connectors? Or do I need to buy a BNC connected current clamp? Thanks! Great videos. p.s: This Zotek model is going to be huge in the DIY market, and bring a lot of people into oscilloscope based testing... you could really corner the market in tutorials if you made a 702/703 specific series of "how to test ________ issue in 5 minutes using a 703/702" type videos.

@KissAnalog 4 месяца назад

Thanks for the great feedback! Yes, I would get the clamp with BNC connector so that you get the benefits of the scope bandwidth. I think that series showing how to use these handheld scopes is a great idea! Thank you!

@rogerrynearson2500 4 месяца назад

I purchased my 703S from AliExpress not noticing it had a 1 or 2 probe option I contacted them to change my order to two probes and the nice person said no problem we send two probes not change order, so I received it had one probe in the box and a second probe loose in the shipping box. I guess the AliExpress people agree, who the hell buys a dual channel Scope with only one probe. The 702S and 703S probes are the same but they are all only 60 Mhz. Not a problem for the 702S but not good for the 703S 100 Mhz spec. I am going to ask for 100 Mhz probes. First order from AliExpress went well.

Do you actually use anything you buy for work or just review it for RU-vid? There’s no way anyone with a desk that small needs that many testing devices.

@KissAnalog 4 месяца назад

Yes I actually do take some devices into work - one to get the job done quicker - and two to demonstrate it to the group so that we can consider getting one for the lab;) Yes you are right - I don't need all this for my work at home. I always have projects going on - more than one at a time;) But much of this is to show others so that they might have options to choose from. I try to compare devices to make this easier. I do have two other benches that are never shown. The camera compresses the image, but the bench you are looking at in front with the multimeters on it is almost 6', and the one with the larger equipment on it is 7' long. That is 13' of bench;)

@mikejones-vd3fg 4 месяца назад

Nice, I got a similiar speced one last year minus the multimeter. and it has done me fine (measuring pwm pin of a MCU etc) until i found a video on it and was disappointed to see the signal jump around in a real audio application. It too measures in the 5-10mhz range by some reviewres although it boast 100mhz, so the signal shouldne be bouncing around at 1khz like in this guys video? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-hdTBvg1mhgk.htmlsi=H84gEHj7yppNxtOx Maybe he doesnt know how to use it correctly, like triggering and what not and I was kind of hoping youd go into that a little more. Oscilliscope basics, probably who'd need it if youre buying a scope at this level. Like theres an auto trigger, manual one, had no idea what that even meant other then pressing auto seems to work fine. Anyway I think i got the jist of it and seeing the bandwidth test was cool and ill have to do it on mine. But now i want to see the switching action of a mosfet, or the recovery time of a diode and still dont know how to do that. Like to capture a fast moment. Are these scopes capable of that or should i be upgrading? I was gonig to recommend these cheap ones but not sure after seeing that video of it being used for guitar effets pedals, unless he's not using it correctly but i was expecting more stable images in audio range, so you can compare easily. Ill have to try myself. Thanks for getting me back in the mood.
