Introducing the Keithley Ke2500 VXIPnP Driver

-------------------------------------------------------------------------------------------------

This instrument driver provides access to the functionality of the KEITHLEY 2500, 2500LV, 2502, and 6482 Dual-Channel Picoammeters.

This driver works in any development environment which supports calling a Dll such as Microsoft® Visual Basic, Microsoft Visual C++, Microsoft .NET, Agilent VEE Pro, National Instruments LabVIEW, and others.

If LabVIEW is detected on the system a LabVIEW wrapper is installed which provides VI's for LabVIEW to call this VXIPnP driver.
