If I remember correct: That was tried already.
The firmwares of the PSU with and without USB connection are different and the Korad KA xxxx D does not support the interface.

Well thanks for the link, but unfortunately it still has the problems I was having with the other software. The graphs are way too small and the program won't let you maximize the window to full screen. I've tried v2.5 and the window is physically bigger, along with larger graphs, but the program still wont let you maximize the window to view it in full screen.

I think that I have V2.3 somewhere. I'll let you know if I can find it. Meanwhile you might try these:

https://github.com/crapp/labpowerqt/releases/download/v0.1.3/labpowerqt_setup_0.1.3_x86_amd64.exe

So does your version not let you maximize the window as well?

I don't remember but you can check it. I sent you a PM with download links.
I hope this could help.

Why is it that none of these Korad software revisions will let you maximize the window to fullscreen? The voltage and current graphs are absolutely pointless if they are too small to see without the ability to make them bigger. The software would be much more useful if you could just view it in fullscreen just like every other program out there under the sun.........but yet you can't  |O. And why is this software so hard to find? It's not even available on the official Korad website! And to top it off, the software disc that came with my unit was blank  :wtf:. Good thing SRA had software download links posted on their website.

Can you post a screenshot? That way we can maybe help.

Hello!

I forgot to mention that you could write your own program to generate graphs without dealing with interface problems if you use sigrok. It's a command line program to control many lab devices. There is a windows version. You can get a text output with a simple script that you could read and plot if you code a little bit. These are some examples for linux.

sigrok-cli  --driver=korad-kaxxxxp:conn=/dev/ttyACM0 --scan (Scan device)
sigrok-cli  --driver=korad-kaxxxxp:conn=/dev/ttyACM0 --show (Show device options)
sigrok-cli  --driver=korad-kaxxxxp:conn=/dev/ttyACM0 --config "voltage_target=3.3" --set (Set output voltage)
sigrok-cli  --driver=korad-kaxxxxp:conn=/dev/ttyACM0 --config "enabled=on"  --set (Enable output)
sigrok-cli  --driver=korad-kaxxxxp:conn=/dev/ttyACM0 --continuous (Get countinuous readings)
sigrok-cli  --driver=korad-kaxxxxp:conn=/dev/ttyACM0 --continuous -o readings.log -O csv (Get readlings to a text file)

I hope this can help to think other options if software doesn't meet your spectations.

Hi
I also forgot to mention. Did you try to maximize the window using a shortcut/keyboard. Windows key + up?

Yes I did. It did nothing. The maximize tab was also greyed out and you could not resize the window whatsoever.

And thank you so much for uploading those different versions of the software for me. They solved my problem. You gave me v2.4 and v2.5. And they both let me view the program fullscreen. I decided to go with v2.5 since v2.4's current graph was not functional. Weird how out of the many versions I tested out, only your two let you view the program full screen. And even stranger yet, your version of v2.5 is somehow different than the version of v2.5 i was using. Yours lets me maximize, mine would not.

Perhaps I'm wrong but I guess that Korad gave license to third ones to build and sell their PSUs. May be that's why there are so many software versions and there are small changes in hardware. This issue made me want to play a little bit with sigrok and gnuplot.

Any way, I'm glad that worked and your problem was solved.

Hi, the light blue resistor R3 is blown on my device (mounted on the upper edge of the board, close to the fan connector) could anybody tell me it's value, so i could replace it. TIA

Well blow me down. Show on stargazing on ABC in Australia with Brian Cox, Australian physicist Allan Duffy etc.

They showed a clip of them st radio telescope Parks I think i electronics processing room and ....wait for it...are you ready.... looks to be a Korad PSU on top of station supplying pwr to some station part.

I think it’s the ubiquitous 5 memory version in question here... here’s the money shot:
Hahaha

I have a Velleman PS3005D 30V 5A  unit.  Have you replace the R3 resistor? Can check R3 resistor in my unit  :-\
