explanation of ke6485 labview program

Hi,

I am new to LabView and i am tasked to measure current using a KE6485 Picoammeter. I tried searching the forums and discussion board and i manage to find a labview program which measured the current. 

I tried running the program, but it showed two errors.

Primary Error: Driver status: (Hex 0xBFFA0010) Invalid value for parameter or property.

Secondary Error: (Hex 0xBFFC0004) Parameter 4 out of range, or error occurred while setting Parameter 4. 

Can somebody kindly explain to me the errors and if possible, can you also explain exactly what does the LabView program does. I attached a copy of the labview program.

Thank you so much.
