2-6 Front Panel Keys
The term hard key refers to all of the buttons on the instrument face except for the vertical
row of gray buttons adjacent to the measurement display. These eight gray buttons are called
soft keys, and they are used to activate virtual soft key buttons within the measurement
display screen. This soft key display area (soft key menu) is also called the active function
block. Refer to Figure 2-2 (item 2) and Figure 2-3 (item 6) and Figure 2-7 (item 6).
Esc Key
Pressing this key cancels any setting that is currently being made. Refer to Figure 2-2
(item 3). The Esc key is located directly above the eight soft keys.
Enter Key
Press this key to finalize data input. Pressing the rotary knob performs this same function.
Refer to Figure 2-2 (item 12). The Enter key is located directly below the Number 3 key in the
number keypad.
Arrow Keys
The four arrow keys (between the rotary knob and the Esc key) are used to scroll up, down,
left, or right. Refer to Figure 2-2 (item 8). The arrow keys can often be used to change a value
or to change a selection from a list. This function is similar to the function of the rotary knob.
The arrow keys are also used to move markers.
Shift Key
Pressing the Shift key (refer to Figure 2-2, item 9 and Figure 2-8) and then a number key
executes the function that is indicated in blue text above the number key. When the Shift key
is pressed (when it is active), its icon is displayed in the upper right corner of the
measurement display area between the battery charge indicator and the soft key menu label.
Back Key
Press this key to delete only one character, one number, or the range that is specified by the
cursor. The Back key is located directly above the Number 7 key in the number keypad.
Plus/Minus (+/–) Key
Press this key to change the sign of numbers that are entered with the number keys. The
Plus/Minus (+/-) key is located directly above the Number 8 key in the number keypad.
