Are your drivers up to date?  Maybe Keithley changed something in between revisions that makes it work subtly different than the last rev.  I've seen this all too often with HP/Agilent, where they changed some commands around from one rev to the next.

Hi,

Did you update you VI's with new Keithley Drivers?  Or are you using their example code?

Or, are you talking about their firmware version?

Thanks for reply. I"ve download that driver from NI site, it's NI approved. I've trace down error source - it's SRQ vi.

Basic operation is OK.

Thanks billko

Yes, I do use a sample code
