PCSU 200 Calibration problem

I,
I’ve got a PCSU 200 and i’ve got no signals.

Calibration results:

CH1 offset at 3V/div : 161 OK
CH2 offset at 3V/div : 161 OK
CH1 offset at 1V/div : 101 FAIL
CH2 offset at 1V/div : 101 FAIL
CH1 Y-position low 57
CH1 Y-position mid 58
CH1 Y-position high 58
CH2 Y-position low 58
CH2 Y-position mid 58
CH2 Y-position high 58

Is it possible to fix the problem?

Thanks

You may try following to test if the oscilloscope is not defective:
If you have Windows Vista, Windows 7 or 8, locate the file PCSU200.ini in the folder:
C:\Users<username>\AppData\Local\Velleman\PCSU200
If you have Windows XP locate the PCSU200.ini in the folder:
C:\Program Files\Velleman\PcLab200

Open the file in any text editor and replace the file content with the following text and save the file:

[Calibration] offs_1=112 offs_2=116 v5_offs1=-4 v5_offs2=1 Ch1_pos0=127 Ch1_pos1=32 Ch1_pos2=224 Ch2_pos0=127 Ch2_pos1=31 Ch2_pos2=224 Ch1_ad0=111 Ch1_ad1=54 Ch1_ad2=169 Ch2_ad0=115 Ch2_ad1=57 Ch2_ad2=173 [Menu] HWdialog=0
Then run the PCLAB200.
The oscilloscope should work now OK without calibration.

Thanks for the response

I’ve got the same problems with the new code. No signal
Have you got an other idea?

There may be either a compatibility problem or the PCSU200 is defective.
Can you test the oscilloscope in other PC?

If you have Windows 7 or Windows 8 you can download and update to the driver available from this page: velleman.eu/support/download … U200&type=
Download, extract and update the driver: “Driver for Microsoft Windows 8”

After the driver update please check in the Device Manager the driver version number is: 13.54.20.543
