  • Page 31: Front Panel Menu Structure And Operation

    FRONT PANEL MENU STRUCTURE AND OPERATION Menu Structure The ESU LT uses a multilevel menu structure containing both menu items and data fields. All menu operations and data are displayed in the LCD window. The opening menu is the access point to all other operations. Each Main menu item has several functions and submenus to identify and access specific parameters.

  • Page 32: Menu Operation

    The cursor is on the first field. If there are more than two menu fields, a down arrow is visible on the lower right corner. See Figure 3- 3 on page 32. Figure 3-2. Cursor on Menu Item Figure 3-3. Submenu Fields ESU LT User Manual 61200410L2-1A...
