How is the rubber? Mine has gotten very sticky and yucky now after a couple of years. Very disappointed. I am watching your video to see if I can just totally remove the rubber shell.
@@KerryWongBlog i used your method with the screwdriver but somehow the rubber has broken down a lot and it ripped immediately even though I used very little force. Anyway will use it without the rubber cover. Won’t be measuring 500 V anyway haha
I already have the Owon and Zoyi and lots pf DMMs. What I WANT is a combo 'scope/thermal camera! I hope someone will do that. For about $200 with decent resolution.
Not only are your excellent videos very helpful for someone shopping the dizzying assortment of oscilloscopes, I find I enjoy watching even though I am no longer shopping. Thank you for your hard work.
Durante la visualizzazione dei grafici, quando la memoria è piena il multimetro si inchioda e bisogna spegnerlo per sbloccarlo, che schifo. La gestione della reimpostazione manuale delle soglie di un grafico è orribile, non compratelo se dovete visualizzare grafici. L'autoscaling non esiste, quello manuale non funziona se la memoria è piena, che schifo. L'istogramma lo trovo inutilizzabile.
Hello i have the same one and we broke it down. I need values about resistor R85, resistor smd r95 and resistor smd r93 and about fuse f2 in order to fix it. Thank you.
Nice review, thank you. Im looking for a little oscilloscope to make measurements in old cassetterecorders, would this be fine, or useless, because of the issues youre telling? Wich one, with the same display-size would you prefer? Thanks (-: Best regars Cookie
The selector knob on my ut210e popped it's clogs this week, I was about to order another one but first I came here to see if you had tested an alternative. After watching your review I bought the same Owon, I'm very pleased with it. Thanks for your great reviews & balanced opinions 👍
I just got a free one for evaluation. This may be a minor point, when I first charged it there was no indicator to say it was charging or when it had finished charging. They always have software issues and the move on to the next model before solving them. I need to document stuff. Why can't they have a USB port to save images to memory.
The charging indicator is the least of the problems. The biggest problem with it is hardware limitations, faulty design and implementation, and software bugs. I still have the 1013D and the DPOX180H and not all bugs have been fixed in them, I think Fnirsi has already abandoned the project. Several people pointed out a physical defect in the DPOX180H, but it was not fixed. It got a new exterior design and that's it...👍 I wouldn't be optimistic about this either. A few months and they release another piece of waste and throw it away... Those who bought it will regret it.
What about using a PAIR of TinySA Ultras, where one is configured as the frequency generator with attenuation.and the other one as the Spectrum analyzer? All the Best! 73 DE W8LV BILL
Also, the number of insersions of an mcx connector is very low before they fail compared to a BNC. Even compared to sma, they are terrible. They are good for just a few insertions or static cables.
02:29 10:19 Kerry, thankyou so much for bringing up the Auto Ranging issue!!! So annoying :( So it's still not fixed? I am on V1.3.2 . I really hope they are able to solve it.
Thanks, good review. I like the form factor, other than the protruding instead of recessed screen. The user interface seems reasonable too. The scant input protection of the multimeter and odd behavior of the oscilloscope on non optimal timebase setting are almost show-stoppers. The good thing is this device has the potential to be pretty good if it gets better firmware and better input protection for the multimeter. No unit has yet to displace my Owon HDS-2102S as my tool bag standard carry, not even the HDS-2202S. I’ve also got the Zotek 702 and 703 models, but both have limitations. I have some hope for the 703 because Zotek has been fairly active at updating the firmware and they’ve fixed a few pretty bad bugs. I like the 702/703 form factor because it feels good in the hand versus the larger Owon HDS models. My largest complaint outside of firmware of the Zotek 702/703 is that the BNC jacks are set too far in and a standard Amphenol BNC plug will not firmly click into its detent when attached.
Yea, the sampling rate would contribute to the odd behavior. One good thing about the Owon HDS series scope meters is that they tell you on the border of the screen what the sampling rate is. As noted, the Owon scope meters are able to properly show the envelope of a modulated fast waveform at slow sweep speeds. The HDS-2102S is still my go-to portable unit.
I bought one of their first battery-operated oscilloscopes. It looked nice, it seemed to be of great quality but the firmware was terrible in every way, the triggering and single mode were totally hopeless, the interface was poorly implemented. And I see the same problems here. I bought an Owon (VDS1022I). It doesn't promise anything amazing but it works as it should.
