Hantek 2000 series - 2C42/2C72/2D42/2D72
<< < (27/50) > >>
Microcheap:
I have being using a 2D42 on my bench for some hobby grade stuff, things like microcontrollers and basic analog circuits and I would not call it junk, instead prefer to say that it is just a basic tool so, people who need it for more advanced stuff might find it some what limiting.
I also have a Rigol DS1054Z as my main oscilloscope but many times I find the Hantek2d42 very practical to just quickly check a signal on a board I am working and I like the fact that I can easily change between scope and DMM function.

I agree that the screen is a bit small and that you might need some time to get used to the controls but i think it is just a trade off of a device that was intended to be portable an cheap. I also don't know an option that will battery powered, packed with functions and cheap at the same time.

I spotted this little scope on Aliexpress another day: https://www.aliexpress.com/item/33021370646.html?spm=a2g0s.9042311.0.0.46064c4dYIVz1v I haven't tried it, but the specs looks interesting although the display is the same size as the Hantek's, it has only one channel and looks more a toy. There was a thread about it here in the forum a few days ago.

Regarding the VDS1022, you can try the app HSscope for Android http://hscope.martinloren.com/ if your tablet is compatible with USB OTG.

Thanks Microcheap.  It seems that opinions are divided on the Hantek 2XX2.  In your opinion, is scrolling and zooming adequate on the 2D42?

On the Owon VDS1022i, I thought that it wasn't working on Linux, so I'm surprised to see that it is listed as being compatible with an Android app.  That is pretty interesting.  Maybe it is the case that only the Owon software doesn't yet run on Linux.  So if the Owon hardware does run with Linux/Android, that device could be useful even with a smartphone.

Microcheap:
You can easily analyze a signal by pausing the acquisition and using the arrow keys on the center of the keypad to zoom in or scroll a waveform, but the level of details you will be able to see will be limited by the amount of memory lengh available (6k single channel).

Guys I got a problem and maybe you experts can help me.

I lost my job because and have nearly no money but needed a scope.

I bought a 2D72 at aliexpress and the scope measures are off.
When measuring a battery with 7.6v the scope shows 8.4 or so volts.
Also when measuring the AWG signal the scope is higher than the signal.
This offset seems to change when I change the measuring range. The larger the range the larger the offset.
See here:  https://www.eediscuss.com/forum.php?mod=viewthread&tid=14904&page=1&extra=#pid18698

Calibration with nothing attached did not change anything (did 3 times).

I bought this with shipping from Spain but the seller wants me now to return it to China, which would be as expensive as the unit.

Questions:
- Can I calibrate with probe attached? And if so shorted? Or will this destroy the unit?
- What might be the reason?
- How might I fix this?

My problem is I got no further measuring equipment besides an cheap multimeter.

A small offset in the channels is normal and should be compensated by the calibration. Can you post a picture of the traces of your scope showing the level of the offset?
