Menu Keys
General – Menus are designed to make TDR setups and cable selection easy as
possible. When making selections in different menus pressing the next desired
menu key will jump directly from the current menu to the new menu. It is not
necessary to escape back to the Measurement Screen after work in each menu
to save the changes and select another menu. When selections are done in one
or more menus press the “Esc” key to save the changes and exit to the
Measurement Screen.
Help Key has two functions: 1. If no keypad functions are active (all
LED’s unlit) and the TDR is not in a menu, the Help key will open its own menu
shown in Figure 1-4.

2. If a function key is active or any menu is open pressing the Help key will
provide context sensitive help about the menu feature pointed at by the menu’s
cursor, sub-menu, or feature being used.
Meter Key opens a menu for making changes in the instrument’s
settings. The Meter’s menu is shown in Figure 1-5.

NOTE: The E20/20N TDR model has only one input port so no INPUT
CHANNEL selection appears on that TDR’s Meter menu.
