PCS500 defective

Dear Sir,

my PCS500 PC Scope is defective. First it died down and it was not possible to switch it on again. The internal Fuse FS1 was burn out, so I replaced it.
Now I can switch the scope on again. But the calibraition fails whenever I start the software. The scope is terrible squeaking and after a while, the communication breakup.

Where can I send it to repair? Or can you give me an advice to repair it by myself?

Best regards,
Michael Lange

Before sending the scope to repair you may try following:
Delete WinDso.ini file from the folder where the software is installed.
Then start the PC-Lab2000 soft and select PCS500 as normally.
The reason to the problem may be that the WinDso.ini was corrupted and the scope gets wrong initial setup.

Thanks for reply.
I deleted the WinDos.ini wothout success. Also I tested the scope on another computer.

I send it to:

Velleman® Components N.V.
Repair department
Legen Heirweg 33
B-9890 Gavere
Belgium (Europe)

Is that correct?

I have a similar proble, when I start the software I get the message “Calibrating - Please Wait…” I have tried it on an old Win95 laptop (it worked on this previously) and on an XP desktop. Under XP the Task Manager shows the processor at 100%. Deleting WinDSO has not worked either.

Please add your country to your profile, this will make it easier for us to locate a dealer.
Or send to:

Oh, sorry. I’m from Germany.
The scope is on the way to Belgium now.

I found the problem with my PCS500. I tried another 9V power supply and it works OK. I checked the other supply and although the output was DC as stated on it the voltage was swinging from around 1V to 20V.
