Change interface to an existing third party VI

Currently, I am in the learning phase with LabView and would like to take an HP34401A multimeter and control it through LabView. I have the instrument connected via GPIB-USB-HS and have been able to download the driver for the instrument. The VI I  am interested in using is the  Agilent 34401 Read Single Measurement.vi, which I have tested and works fine. What I would like to do is remove the interface that is there now and request the user to select which type of measurement is desired and what the range is. As long as the measurement is within the range, I would like the data stored to a file. Since I am new to this environment, any assistance to this is greatly appreciated.
 
Thanks!

You've posted to the TestStand forum. Are you using TestStand or just LabVIEW? If it's just LabVIEW, then all you have to do is use the VI you posted as a subVI in a main VI that you write. The main would have controls for the measurement type and range and maybe a Boolean labeled 'Measure'. When the user clicks the "Measure' button, the subVI gets called and returns a value. Using an event structure would be a fine way to structure your program.

Since you are new to LabVIEW, I would recomend you check into the free tutorials at http://www.ni.com/academic/lv_training/how_learn_lv.htm.
