Hi, I was trying to write a code to control a Keithley 2400 source meter. In the computer I installed Labview 2017 since I have an old code that I needs to run. I installed Labview NXG 2.0 and the latest NI-VISA (17.5). The GPIB card is KUSB-488B and I installed the latest NI command compatible driver (KI-488_v3.13) which I downloaded from Keithley. I also installed the certified instrument driver 'Keithley 24XX Labview Plug and Play (project-style) 1.2.5' from NI Package Manager. I run the sample code 'Keithley 24XX Read Single.gvi' provided in the instrument driver in NXG 2.0 and I got an error message as follow,
Error -1073807202 occurred at Keithley 24XX Read Single.gvi
-->Interactive:Initialize.gvi
-->Interactive:NI: Open (Instr).gvi:2340001
-->Interactive:NI: Open.gvi:2160001
-->Interactive:NI: Set Error Code.gvi:520001
Possible reason(s):
LabVIEW: (Hex 0xBFFF009E) VISA or a code library required by VISA could not be located or loaded. This is usually due to a required driver not being installed on the system.
I run an old code I wrote last year in Labview 2017 and everything was fine. I also checked NI MAX and it recognized the GPIB card. VISA test panel also showed no error at all.
Does anyone have or had such issue? Any advice on how to solve it?
Thanks a lot.
Rui
