Sorry but I don't have a program for that instrument.  What I do remember when I developed my VI for the 2000 and the 2701 (using RS232 & ethernet) is that I had to put a slight (50ms) in my code after I sent the :read? command but before I did the visa read to give the meter a chance to send the data back.  If I didn't do that, it would hang.

 

If I were you I would open a blank vi and start writing your own interface using the SCPI commands in the manual.  One command at a time, including error handling and "highlight execution" while watching the meter's display...which will tell you if you have sent invalid or out of range commands, syntax errors, etc.

 

Using RS232, you can start with a simple Open, ":IDN?", delay, ":Read?", Close, to make sure you're even communicating.  Once you've established that, you can start stringing commands together to get the meter to return the data you want.
