Instrument handle connection

[sheabird]

I am new to labview programming and have no clue what the instrument handle connection is for on the Agilent E3631A instrument VI.  This is a power supply and for the most part the connections make some sense to me but not this one.  Can someone advise on what to do with this terminal?  It looks to have something to do with I/O protocol choice if I open the VI.

Hi Sheabird,

I'm not familiar with that particular PSU, but I hope I can help.

Usually there is an initialisation VI (InitWithOptions) that will return an instrument handle.  This can then be wired into other functions (e.g. SetCurrentLevel) to reference that instrument.
