2-5 Data Entry
User input can be in the form of numeric values for instrument or measurement settings,
selected values from a preset list, or alphanumeric text when entering file names, for
example. To view or change a parameter value, access the appropriate submenu by pressing
one of the five main menu keys along the bottom of the interface screen, then navigating
through the touch screen submenus.
Other instrument functions are accessible from the numeric keypad, when used in
combination with the
Shift
key. Refer to “Numeric Keypad” on page 2-3 . Some of the
parameter settings displayed on the left of the interface screen or under the title bar are
touch screen shortcuts to related submenus.
Depending on the measurement mode, refer to the associated Measurement Guide listed in
Appendix A for a description of available menus and submenus.
Numeric Values
To modify a numeric parameter setting that is displayed on a submenu touch screen key,
press the key to make it active. The display color of the currently set value changes to red.
Use the rotary knob, arrow keys, or the numeric keypad to change the value. When entering a
value from the keypad, the submenu typically shows the selectable units. Press the desired
unit or press
Enter
to complete the entry.
Selection Lists
Some parameters and instrument functions are selectable from a pop-up list. These list boxes
display the available selections, and value limits if applicable. Use the arrow keys or the
rotary knob to scroll through the list and highlight the desired entry. You can also use the
touch screen to make your selection.
To apply the selection, press
Enter
. To exit the selection list without making a change, press
the Escape (
Esc
) key.
