Keithely 2400 voltage sweep and measure current

[srms]

Hi,

I have written a labview program(Attached) to sweep voltage and measure current in keithley 2400 source meter. My problem is, I get current output as zero for  all the values, but current values are displayed on the source meter. I would appreciate if somesone can help me to figure this out.

Thank you in advance

In the recent driver the following vi is added.

\instr.lib\Keithley 24XX\Public\Configure\Configure Data Communication Format.vi

and select Volt and Amp. 

It is also better to read and voltage and current. all other  info is either not interesting or even wrong (time)
