Please help on this program

[Chemical]

Dear Friends,

With the help of this program I am trying to connect two instruments (One is CM110 monochromator of Spectral products and another one is from Keithley 2400 source meter) with the same programs. With the help of this program I am trying to increase the wavelength of the monochromator by say 10 nm and want to read the current at applied source meter voltage. 

But the problem is each execution of while loop it is keeping ON/OFF the souce meter applied voltage . I want to keep the applied source meter voltage on through out the whole while loop and read the current, but I am not able to do so.

Please help me. For your further information I am attaching the LabVIEW Program.

Thanks in anticipation

Regards

Chemical,

You may want to try initializing and closing the Keithley outside of the main loop.  Regards, -SS

 Thank you for yr propt reply

I have tried this .

Initialize and closing the keithley out side but it is still not working...It is only because in that case I am not able to tell keithley that the wavelength is now incremented and now you have to take reading...Please explain how can I do this...Before yr answer I request you to have a look on the programm...

Regards
