Inside the new Korad KA3305P linear PSU
YottaByte:
I just received a "refurbished" KA3305D from SRA. Their tech said that any returns for whatever reason are thoroughly tested before being resold, so of course I expected everything to work. But unfortunately that wasn't the case. On Ch3's 5V fixed terminal I only get a few mv output. Any suggestions before I call their tech support Monday? Thanks.

It may be a stupid suggestion, but are you measuring between the + and - and not the - and the GND?
:D
YottaByte:
SantaClaw,
Thanks for the quick response! No such thing as a stupid question. The mv output is between the + and - terminals. I haven't opened the case to check inside. Just disappointed, especially after talking to the tech who confirmed that refurbished units were thoroughly tested. BTW, the PS looks brand new, only the user's manual was photocopied.
SantaClaw:
Yeah, well, then I'm out of suggestions, I just measured mine, it's pinned at 4.98v, if I set the two other channels to 5.00v they measure at 4.99v, but that could be my meter as well...
YottaByte:
Thanks, I'll just have to wait until Monday to call them.
