3.2.3 Configuration and Trim Menu
The Configure/Trim menu provides access to the menus used to assign parameters, define functions and
trim input and output signals. This group of menus should rarely be needed as the instrument was
configured at the factory before testing and shipment. The basic structure is as follows. See the “System
22 Configuration Manual” for details about these menus, available at
www.ecdi.com .
