3.6.2 Function / Data Keypad Layout and Protocol
The RPM4-E-DWT has a function/data keypad for local operator access to direct functions,
function menus and for data entry.
A The Function/Data keys allow very commonly used
functions to be accessed directly by a single
keystroke when pressed from the MAIN RUN
screen (see Section 3.6.1). The name of the
function is on the bottom half of the key. These
keys enter numerical values when editing.
B The Editing and Execution keys are for starting
and suspending command execution, cursor control
in menus and editing entries.
C The Menu/Data keys provide access to function
menus when pressed from the MAIN RUN screen.
The menu name is on the bottom half of the key.
The SETUP menu is for more frequently used
functions (see Section 3.8). The SPECIAL menu is
for functions that are not generally used as a part of
day to day operation (see Section 3.9). These keys
enter numerical values when editing.
Figure 14. Keypad layout
Lo Q-RPT (ref pressure transducer) Pressing [ENT] generally causes execution or forward
movement in the menu tree.
Pressing [ESC] moves back in the menu tree and/or causes execution to cease or suspend.
Pressing [ESC] repeatedly eventually returns to the MAIN RUN screen and, from there,
allows momentary viewing of the RPM4-E-DWT introduction screen.
Pressing the [+/-] key changes a numerical sign when editing. It also toggles through
multiple screens when available and, from some run screens, is a shortcut to a momentary
display of active RANGE.
Pressing the [ ] , [ ] , [ ] and [ ] keys allows up, down, reverse and forward cursor
movement when editing data entry or moving in menus.
Note
Some screens go beyond the two lines provided by the display. This is
indicated by a flashing arrow in the second line of the display. Press
the cursor control keys to move the cursor to access the lines that are
not visible or directly enter the number of the hidden menu choice if
you know it.
3.6.3 Optional Remote [ENT] (ENTER) Footswitch
Operating the footswitch is the equivalent of pressing [ENT] on the front panel.
The remote ENTER feature can be particularly convenient when running AutoTests (see
Section 3.1.3) in which the operator’s hands are not free or attention is on the device under
test rather than the RPM4-E-DWT.
