Saying that it is straight forward is not what you want to read, right?
ok....
I'm not sure about instructions, but if you installed the driver and opened the library, you will get sub-vi's which have a particular application (purpose).
The best way is to open the sub-vi which appears to be what you want to do and run it. Look at what you are measuring and see if it is useful. Get acquainted with sub-vi's. Soon, you'll combine them into your own vi and you'll prefer using the multimeter through Labview rather than pressing the buttons.
Don't be afraid of experimenting. (with the vi's that is!)
;o)
