Menu Screens:
These top-level and lower-level (sub-
menu) screens within the three main branches of the
menu tree are used to access edit/selection screens for
configuration. (EXIT screens at the end of each menu
branch enable you to move up one level in the menu tree
by pressing the
ENTER key
. This is functionally the
same as pressing the
ESC key
.)
•
Edit/Selection Screens:
These screens enter values/
choices to calibrate, configure, and test the analyzer.
The keypad enables you to move throughout the analyzer
menu tree. The keys and their related functions are:
1.
MENU key:
Pressing this key always displays the top of
the menu tree (“MAIN MENU” selection screen). To
display the top-level menu screen for a desired main
branch (CALIBRATE, CONFIGURE or TEST/MAINT), use
the
Ø
Ø
and
×
×
keys
to select the corresponding line, and
press the
ENTER key
. (Pressing the
MENU key
also
“aborts” the procedure to change values or selections.)
2.
ENTER key:
Pressing this key does two things: it dis-
plays submenu and edit/selection screens, and it enters
(saves) configuration values/selections.
3.
ESC key:
Pressing this key always takes the display up
one level in the menu tree. (Example: With the “MAIN
MENU” branch selection screen displayed, pressing the
ESC key
once takes the display up one level to the
MEASURE screen.) This key can also “abort” the pro-
cedure to change a value or selection.
