SECTION 4 - PROGRAMMING GUIDE

USING THE BATTERY SIMULATOR IN LabVIEW

Finding the Driver

During driver installation Pickering LabVIEW libraries are installed into the ‘instr.lib’ folder of the LabVIEW installation.
This is accessed from the ‘Instrument I/O’ – ‘Instr Drivers’ palette in LabVIEW.

The LXI driver package is shown above, however similar palettes are available from the pipx40 (PXI-VISA) palette

and from the pilpxi (PXI-non-VISA) palette.

Example Program

A simple LabVIEW program to control the Battery Simulator is shown below.
