General Menu Operation
The TSU 120 uses a multilevel menu structure
containing both menu items and data fields. All menu
operations and data are displayed in the LCD window.
The menu items are numbered and can be viewed by
scrolling with the Up and Down Arrows.
• Data Field
A menu item followed by a colon (:) identifies a data
field that can be edited.
• Display Field
A menu field followed by an equal symbol (=)
identifies a field used for value display and is not
available for editing.
• Arrows
Menus that display small Up or Down Arrows in
the lower right corner indicate there are more menu
items than are viewable on a two-line LCD. The
additional menu items are accessed with the Up or
Down
Arrows. Undisplayed menu items are also
available by using the appropriate menu number.
Select and Activate a Menu Item
Place the cursor on the desired menu item by pressing
the number corresponding to the menu item or
highlighting the menu item with the Up and Down
Arrow
. In this example place the cursor on
2)CONFIG. Then press Enter or the number a second
time. See
Figure 3-2.
