problem with changing computer (GPIB)

[upjs]

Hello everyone!

I have one very strange problem.

I wrote program to communicate with electormeter Keithley 6517B at one computer. I have tested it and everything worked fine.

For measurments I need to use notebook and transfered this program into notebook.

So 2 strange things happened:

1. Measured resistivity is ALWAYS equals to 1 (should be 1.5 MOhms) 
2. Testing a previous version of program (without automatic measurments and so on) gives a right value of resistivity = 1.5 MOhms.

Any ideas?

What language are you developing your code in (LabVIEW, Visual Basic .NET, etc)? You mention a previous version works. What changed from the previous version to the new version? You mentioned automatic measurements, what functions are you using?
