Have you used the Owon HD200 series handheld scopes? Could you comment or compare?

[@darylmcgee4349]

Hi Richard, I see in the specs for the link provided that it is 9999 counts. I can also see other listings that say 19999 counts so it may be something to look out for when purchasing. Hopefully just a typo on a few of the listings :)

[@LearnElectronicsRepair]

There are two models, 2C23T 9999 count, 10MHz and 2C53T 50MHz 19999 count. The link takes you to a listing that has both models so make sure you click the one you like best

A direct competitor of Zotek ZT703S?

[@jcbritobr]

What I have seen, it's the best 3x1 today.

[@shaunmorrissey7313]

Give me the Zotek anyday.

[@LearnElectronicsRepair]

@@shaunmorrissey7313 I've not tried the zotek but I could ask them for one to review

Heya, that looks like a nice tool

[@watchmakerful]

33.3 kHz is NOT too close to the correct value. Either the probe is disturbing the oscillations with its input resistance, or the frequency is not measured properly.

I've a huge problem with these scopes, because at the low cost end they are likely to be purchased by amateurs or possibly even parents for children and are almost certainly to be used at some stage on a mains connected device. And given the target market, much of the low cost mains powered equipment it is likely to be used to diagnose might not be well designed or safety rated. So if anything they should be even safer than high end hardware, but .................. !

[@LearnElectronicsRepair]

Yeah it's amazing us electronics hobbyist kids ever survived our early teens as everything was mains powered, a lot of vacuum tube kit in the early 70s when I started, and we didn't generally have parent who could guide us, they didn't teach electronics at school and we had to go to the library and loan books to learn for ourselves. We never thought it was a huge problem though. What has the world come to 🙄

[@cpcfreak]

@@LearnElectronicsRepair I suppose not everybody did survive which is sort of the point when we consider the safety of a design. It's easy to state "be safe", while sitting at our isolated workbench with current limited variac dim bulb testers, etc., etc., and a subboard full of RCBO. At least a regular multimeter doesn't expose bare chassis to the world.

[@OnStageLighting]

No blip in diode mode, first deal breaker for me at the moment. They can probably sort in future firmware.

[@Foobar_The_Fat_Penguin]

But will they? If you browse through the downloads section of their website, it looks like most of their gear never gets a firmware update. There's only a few firmware files available but no changelogs. I get the impression that FNIRSI in general quickly abandons older products in favor of new releases. They seem to have a new device for review every couple of weeks.

[@OnStageLighting]

Having said that, I feel that these products stand or fall on the scope/sig gen functionality from a battery device and the DMM is just there because it is. Some good things about a battery scope is slightly fewer concerns over ground / isolation on a mains powered DUT. Bad things are either reduced functionality eg. triggering OR same functionality but a bugger to access with the simple physical UI. In a future video, it would be great to skip the Auto and try using the functions manually. All simple battery scopes can be tricky to, say, shift the H, shift the V, adjust the divs, then tweak the trigger - all stuff that we want from a scope. Be interesting to see how the functions are accessed in this case.

[@LearnElectronicsRepair]

@@OnStageLighting I think these scopes while not perfect are pretty good for beginners and fixers alike. For the price it is a useful bit of kit. Out of all my multimeters only three pass the Mr Bleep test: The 1990s Fluke 79 which is my day to day workhorse, the ET13S which I use mainly for the built in thermal camera and the cheapo one I modified myself to integrate the bleep feature just because I can.

Every time something new comes out, it gets worse!
