Hi Gene74

Are you getting any error code? Which was the resource name in the old computer and which is the device name in the new computer?

Hi DicHutchings

It seems that the driver that you are using is the Keithley driver on not the NI driver. I think that the clear function will close the reference, but I am not sure as I have not use that driver before. That solution should work, but keep in mind that if you are constantly creating and closing the reference you are unnecessary repeating code and eventually might generate an error. From my point of view it will be better to initialize the port, run the sweep on the subroutine and at the end of the execution close the reference.

It will be better to create a new thread, but if those drivers are from keithley it might be better to post the question in a Keithley forum
