I am trying to take a resistance measurement from my Keithley 2400 Instrument and import that data to LabView 2013 SP1. I am running the Keithley example LabView program Read Single (attached). I keep getting the error "VISA: (Hex 0xBFFF000E) The given session or object reference is invalid." This error pops up after the time out (10000 ms). I established communication with the instrument in NI Max and sent an IDN command which returned with no errors. I downloaded the proper drivers for Keithley instruments and installed the latest version of NI VISA and LabView 2013. Any help would be greatly appreciated.
Full error:
Error -1073807346 occurred at VISA Write in Keithley 24XX.lvlib:Error Query.vi->Keithley 24XX.lvlib:Configure Measurement.vi->Keithley 24XX Read Single.vi
Possible reason(s):
"VISA: (Hex 0xBFFF000E) The given session or object reference is invalid."

I specified "COM3" in the VISA Resource Name drop down box. LabView is detecting that there is something connected to the USB port, but I have not been able to communicate with the actual Keithley 2400.

I selected COM3, I did not type it. MAX recognizes the serial to USB (it shows up under Devices and Interfaces). I think that the problem is that MAX recognizes that there is a serial to USB hooked up but I can't communicate with the machine.

The "machine" being the Keithley 2400 SourceMeter.

Hi I am also getting the same error in Lab View when I try to use the read singles example for the case of my Keithley 2410 SMU.
The screenshot is attached. Please let me know if any more information is required.

I am having the same problem with Keithley 2450. Just wondering how you guys solve this issue?
Any help is appreciated!

In my case..eventually it turned out that the GPIB I was using was not compatible with the Kiethley SMU. I had been using a Prologix GPIB. As soon as I switched to a NI GPIB, it worked for me.
