Sir,
      Can i use a drive of Keithley 2182 working in labview 5.1
environment
       instead that of a keithley 181(both of them are
nanovoltmeters)with some s       slight variations in the drive.
        I am trying for such an option as i didnt got a drive for 181
working in
        LabVIEW 5.1 version.
        If any one can help in this regard it will be greatly
appreciated.
        regards,
        Libu,
        IIT Bombay.

You can if the command sets are the same or similar. You'll have to
look at them and compare. If you only need a few functions, it might
be simpler to just write them from scratch.
