Hi everyone

I'm beginner in labview and I'm getting the error: VISA:  (Hex 0xBFFF0015) Timeout expired before operation completed.

This is my vi file. I cannot understand what the problem is..

PS: I'm using Keithley 2612 with RS-232 connection.

It looks like you just tried to copy C code into your VISA writes.  That will not work.  You need to use the proper SCPI commands as documented in the manual.  Alternatively, you could download the LabVIEW drivers that Keithley provides.
