#VoltLog #HDS242S #Review - Наука та технологія
This was an excellent break down! My multimeter died on me right when I was about to finally buy an actual scope. So i went from needing an Osciloscope to needing a new MM and Scope. So my choice was to either buy a Fluke 115 and then buy a cheap single channel scope later or buy the OWON HDS242S. I know that as far as the multimeter is concerned the Fluke would have been a much better buy. But since im only using it for home use (i build guitars, guitar pedals and do guitar amp, pedal and guitar mods etc.) i could probably get away with a 20MHz bandwidth scope if i needed to. And as far as the meter goes i still have my first meter that i use as a backup. Its really basic and can measure capacitance or temperature (which is good for calibrating my Soldering Station so ill have to get another thermocouple device) but its accurate and built in such a way that when something goes wrong I can fix it unlike the meter i bought 2 years ago that just died on me. The one that just "died" started draining my batteries and i traced it back to a really really poor unreliable switch design. And even if i took the time to fix it id always be worried its going to kill my tenavolts or start a damn fire. So no more cheap meters for me. I might not be able to afford a Fluke 87 but i can at least get something that should be more reliable. If i have any issues with the OWON ill just get the Fluke 115 and a cheap single channel scope. Anyways, this really was an excellent break down and i found it very helpful and informative. Great job!!
2:25: Recommends adding screen protector to prevent scratches.
Milliseconds later: peels off factory screen protector ;).
stopped the video and went down to the comments for that
I was expecting this comment 😂
I have HDS272 purchased on 5/2021. It came with V1.5.0 . I emailed OWON
factory and received/updated to 1.7.0 .
thank you so much, great vid, although, some of the comments here about showing oscilloscope at close to limits stability is a major plus, thanks for your efforts, great work.
Hello, can you use the multimeter leads to input and see the sinewave from an electrical socket? I've been searching everywhere for this answer as i'm new to oscilloscopes.
hello, do you know if this oscilloscope can detect voltage transisions clearly for communications such as spi, iic, uart, can, standart 802.3? I also require it to measure injection voltage to a dc stepper motor. Do you think it is enough for me or do I require one with a higher frequency and sampling
Would of be useful to see how well the frequency bandwidth could reach with a stable reading and if it could read a 50Mhz square signal.
Do you know wether the given max input voltage of 400 volt refers to X10 attenuation or is it the X1 value. I only found conflicting information about it...
While the input terminals clearly say 400V the manual relates this value to an X10 attenuation??
Занимательная вещица! спасибо за показ внутренних органов.
Great video. Please do a video on owon hds272s software demo showing Windows PC features when connected to Scope.
Thanks for the review. I would like to have seen various waveforms near the max frequencies of this unit to see how realistic its ratings are. The refresh rate example was valuable as update rate is always a critical test for these handheld units, but that's the only real oscilloscope test that we got to see.
To sum it up, the unit does meet it's spec and Owon is a known manufacturer, there is no reason to suspect the specs are not real because they are building a brand, they are not just some no name brand that sells on Aliexpress. Unfortunately reviewing 3 instruments into a single video is not really possible unless a lot of stuff is skipped and the video already got too long.
@@voltlog 25 minutes is not too long, especially for someone interested in details. If you place timestamps so people can jump, then you can easily make your videos as long as you want. Just a suggestion ;) Thanks for the review, it was helpful.
Thank you. Right now the HDS242 (no S) is less than 100 EUR incl. VAT in Germany - so an absolute bargain.
hello. it can write data stream to internal memory?
OWON HDS2102S vs Tektronix THS720A
Which of these two devices would make sense to buy?
Does it have the feature to see the duty cycle?
My HDS242 has firmware v1.8.0, ordered on banggood at 1st june of 2021
I bought the Owon HDS242 back in April 2021 for USD 119,
it has version 1.8.0 of the firmware on it.
Would be nice to be able to upgrade it.
I will ask Owon about it and do a follow-up video if they reply.
Unfortunately, I read they have limited upgrade possibility of their older units but it may worth a try asking them about a potenntial upgrade.
Can it interface with a mac or pc?
I got this oscilloscope. It is kinda slow but got the job done.
Nice product
just because you asked: I just bought the HDS242 (no s so no function generator) for 99 Euro Bucks and it has FW 6.1.0 preloaded. A very nice device with a lot of features for a very low price. So now I can analyze stuff connected to mains without accidentally frying the mains connected scope through a short
Do you know wether the given max input voltage of 400 volt refers to X10 attenuation or is it the X1 value. I only found conflicting information about it...
While the input terminals clearly say 400C the manual relates this value to an X10 attenuation??
@@juergenscholl2843 I do not know for sure. But Pollin (where I bought it) says in the tech specs that this relates to 10:1 attenuation. I would not apply the full 400V to the input terminal.
@@radlrambo4994 Danke! Es bedeutet dann aber auch dass 230V Wechselspannung eigentlich nicht gemessen werden kann/soll mit X10 weil Peak to Peak nur 400 V sind?
Dankeschön für deine schnelle Antwort. :-)
@@radlrambo4994 So even with X10 one shouldn't mess with 230V AC as it's beyond the peak to peak limit ...
Thank you for the reply 🙂
Womit gehen 230V dann zu messen? Stromzangenwandler?
A shrouded BNC to banana adapter would have been a nice addition. Not sure why they are so expensive.
I would have liked to see a short BNC cable included or maybe the option to electronically switch the AWG output to one of the scope inputs, that's really useful for educational purposes.
thats a prety nice piece of kit where can i sell my liver to get one
.... Reminded me of the Python sketch in 'The meaning of Life' (1983).
Tried reading in scope mode 150 kHz 32 V AC, VPP registered but frequency wasn't being read. This is a toy !
Did you use x1 or x10 probe?
How much is it and one like it
👍👍👍
Is there a review to see if it matches its promises ?
What promises?
Like the specs and wfms/s or maby detailed test of function gen ? More in depth review i mean.
@@thomasw6169 There are also other relatively new reviews about this product like ua-cam.com/video/AFxSrieoI64/v-deo.html and ua-cam.com/video/lbvqnWPC6iQ/v-deo.html
The more reviews the better anyway.
Personally, I think it is a really great value for money, I have found it is much better than what I thought.
It is really an instrument and not a toy like FNIRSI-5012H which I also have but I was really disappointed considering its specification a few years ago and made a comparison (for myself) yesterday of my 5012H, Owon HDS272S and Siglent SDS1202X-E and found it is really close to what my Siglent shows within the Owon's specification but 5012H is really a joke and also the original probe of 5012H is crap while Owon's probe seems to be good for the product.
Current revisions of this product seems to have faster auto set function and faster multimeter functions than older units - mine has the same speed like in the video, it used to be slower.
Just saw jerry wong. Omg. Does this thing really have isolated channels ? That would be absoute killer feature.
Channels are not isolated from each other but naturally isolated from ground as it is a handheld unit.
Also, basically there is isolation between multimeter and scope part which is another question.
So be sure to take attention of scope channels are not isolated from each other and one can make short-circuit with GND of channels and also it can be dangerous if one connects GND to mains.
This scope would be so much better if it showed volts per division
it shows
Bis 31.01.2023 für 120€ zu haben bei Pollin in der Variante ohne Generator
It's build quality is worse, Hantek 2d72 is much better or a 2c72 also can be converted to 2d72 it's muck cheaper, had battery drain issue and doesn't power on sometimes, and firmware glitches .. Internal board quality is worst.... Full of flux everywhere...
I cannot comment on the Hantek units as I have not looked at one yet but as someone who has seen board quality from bad to very good, this one is up there between good and very good. There is nothing wrong with the quality of this board with the exception of that electrolytic bodge which has good soldering and adhesive holding it down.
You bought both so you could compare?
I bought my Owon HDS242 for USD 119, where can i buy the Hantek cheaper?
@@geirendre check in detail on nickbel forum and eevblog, users had a lot of complaints on it... And just for 40 MHz 119 $ is quite high.... Actually 40 MHz is better compared to 70 MHz , because both of them are topping out at same 100mhz... There are no hardware changes at all between 2.
@@geirendre you already bought an improved version, use it well, hantek had a lot of custom support on Russian and Australian forums compared to owon...I too thought of buying owon but a user in the forum bought 2 and he said that hantek is better in quality and support, owon is better feature wise he is disappointed about internal board quality... If you have owon better don't buy hantek they both are same, better go for something totally different in higher range..
There were complaints about its speed and some late modifications on the board like more resistors on top of each other and some of them were soldered in strange positions.
Since then, they have greatly improved speed and these late mdifications have disappeared except one additional electrolytic capacitor which would be a harder modification because of few space.
So, basically these problems have gone and I find build quality is good.
