Reference #
Front Rear Nomenclature Function
4 ◄ and ► Keys Used to assist navigating between levels of the menu structure while in Menu
Mode or Zero/Cal Mode and to select individual editing numeric parameters.
The ◄ key serves as a ―Previous
‖
key during menu operation, and will navigate
back to the next higher menu in the hierarchy unless the user is in digit editing
numeric entry mode.
5 ▲ and ▼ Keys Used for incrementing or decrementing numeric parameters, selecting from lists,
or scrolling through multi-line or multi-page displays. In this mode, holding the
key will auto-repeat after a short delay, and the increment rate will speed up.
The ▲ and ▼ keys may also be used to jump between the first-level submenus
in the menu hierarchy. For example, if the Trigger menu is selected, pressing ▼
will move directly to the Time menu, which is adjacent to the Trigger menu in
the tree. This eliminates the need to return to the top of the tree and select the
Time menu from there.
6 Soft Menu Keys Five application-defined keys which enable the user to perform an action, enter
or change a parameter, or select a submenu. When the menu display is active,
the LCD display will show a ―menu box
‖
next to each active key with that key’s
current function.
7 Numeric Entry Keys The numeric entry keypad is used for entering numeric parameters directly.
This process will normally pop up a numeric entry window which permits entry
in various units.
8
Esc/Stop
Key Aborts any operation in progress when in Menu Mode or Zero/Cal Mode.
Pressing
ESC/Stop
while running in Text Mode or Graph Mode first causes the
measurement process to stop. Pressing it when already stopped will clear the
screen and reset all measurement values. Pressing
ESC/Stop
when the
instrument is in remote mode (a remote bus has control of the instrument and
keyboard entry is disabled) will return it to local mode (the instrument is under
keyboard control) unless the local lockout command, LLO, has been issued by
the controller.
9
Menu
Key Enables the menu display (if off), and resets menu navigation to the top ―Main
Menu
‖
level of the menu tree. Pressing and holding
Menu/Menu Off
for one
second while already in Menu Mode switches the menu display off and provides
a larger screen area for measurements, which permits more text measurements to
be displayed, and higher trace resolution in graph mode
10
Graph/Text
Key Pressing
Graph/Text
places the instrument in Graph Mode to display the
current measurement waveforms (traces) in a graphical format. Pressing
Graph/Text
while in Graph Mode toggles to Text Mode, which presents a
numeric or tabular text display of the current measurements.
