3.4.2 Navigating and Editing
The <left/right arrow> keys are used to cycle through the following menus: RUN MODE, PARAMETER, DET VID,
FUNCTION, GRAPH 1, GRAPH 2, GRAPH 3, DETECTORS, Graph 1 display scale, and Graph 2 display scale. The
heading for the current menu is highlighted. The active option within each menu is also highlighted. The <up/down
arrow> keys are used to select a specific option (marked with an asterisk “*”) within the selected menu and the
<Enter> key is used to activate the option. To adjust the value of a numeric field (dynamic parameter or graph display
limit), use the <Home End> keys for coarse adjustments, <Page Up Page Down> keys for normal adjustments, the
<+-> keys for fine adjustments, and the </ *> keys for very fine adjustments. Number pad and keyboard give the same
results. Each field is described below.
3.4.3 Run Mode
The first menu in the Real Time screen controls the run mode. The options are Quit, Run, or Run/Edit.
Upon entering the Real Time Screen, the run mode is Run/Edit which enables the display and parameters to be edited
using either cursor motion or the Quick keys.
Once operating conditions have been established, the Run mode may be selected to disable the Quick keys and editing
capability. This may be useful to avoid problems caused by pressing a key inadvertently. In Run mode, the user may
adjust the display, but can not adjust any of the dynamic parameters are operating functions.
Quit stops real time operation and returns program control to the main menu. The hardware continues to control and
monitor temperatures but any open data storage files are closed. The <escape> key has the same effect as selecting
Quit.
