We're some labview beginners having a similar problem. Maybe you guys can help us out.
We're building a similar program just for reading the data out of two keithley 2000 DMMs and making a voltage drop measurement. We're trying to characterize a diode as a project, but we can't get the data to export in a reasonable fashion. We end up getting 1 data point every second or so and the program writes it as its own file. We want a continuous datasheet so that we can analyze the data further.
I've attached it so that ya'll can tweak it as necessary or just give us any pointers.
