# Using an Instrument Driver

To load an instrument driver, select Instrument»Load and then select the .fp file in the Load Instrument dialog box. You also can drop a .fp file onto the Library Tree. After you load an instrument driver, you can access the functions from the Instrument menu or the Library Tree.

If you have a project that uses functions from an instrument driver, add the .fp file for that instrument driver to your project. If you add a .fp file to a project, that instrument driver will be loaded automatically each time that the project is loaded.
