LabVIEW driver for 6514:

LabVIEW driver for 6221:

You will also need a GPIB interface card, like this:

If your Keithley devices have RS232 ports (no idea), then you could also work via serial port, would be cheaper.

can you please send me the programm in using serial port because i m not in labview programming

In short: buy me two bottles of these, and I will write you the program: http://www.biernavi.de/brew-dog/tactical-nuclear-pinguin/?lang=de 😉

In longer version: we are not here as free program writers for lazy people. Start learning LabVIEW, check the Keithley drivers (they include example codes), and try to program yourself. When you get problems with your VI, come back here, attach your VI with description what you tried, and what is your goal. We even do not know your measurement. You did not give enough information.

i tried but  error is there i.e. error-1073807195 occurred at VISA . Write in low current.vi

This VI looks strange, the flat sequence structure is not needed either.

1. Did you download the drivers from the links above?
2. Put these drivers into the instr.lib folder (c:\Program Files (x86)\National Instruments\LabVIEW 2015\instr.lib\), and restarted LabVIEW

The Tektronix website (merged Keithley one in) went crazy, they do not let me download the driver:

"In compliance with U.S. Government regulation, Tektronix is required to review all software download activity. This process may take up to one U.S. business day and you will be notified when the process is complete. We apologize for any inconvenience.
If you have any questions, please contact us at ...."

Try to get these drivers first, and then check the examples included. That is all I can say.

By the way: did you connect your PC to the Keithley instrument? Do you use a GPIB or a RS232 interface? Do you have drivers installed (i mean GPIB or the RS232) for Windows?

Ok, I managed to get the driver via the German website of Keithley, I have attached it, unzip it into your instr.lib folder!

Here is one example VI, try to use it (C:\Program Files (x86)\National Instruments\LabVIEW 2015\instr.lib\Keithley 622x LV 2009\Examples\KE622x -- Setup DC Current Source Example.vi):
