Any function can be selected at any time. Just scroll through the MAIN
MENU with the DOWN/UP control to the appropriate function, and ENTER
it. The analyzer will immediately start that function, unless password
restrictions have been assigned. (Password assignment is explained further
on.)
All of these functions are described in greater detail in the procedures
starting in section 4.3. The VFD screen texts used to illustrate the procedures
are reproduced in a
Monospaced type style.
4.2.2 Data Entry
4.2.2.1 ENTER
When the selected option is a function on the Main Menu screen, the
function name appears between the arrows on the screen. You activate the
function by turning the ESCAPE/ENTER control to ENTER.
When the selected option is a function or subfunction, ENTER moves
the display to the VFD screen for that function or subfunction.
When the selected option is a modifiable item, the DOWN/UP control
can be used to increment or decrement that modifiable item to the value or
action you want. Then you ENTER the item, which also puts you into the
next field to continue programming.
When the last field is entered, ENTER takes you to the next screen in the
process, or if the process is completed, ENTER takes you back to the ANA-
LYZE screen.
4.2.2.2 ESCAPE
A turn-and-release toward ESCAPE moves the blinking to the next
field on the left. When you are on the leftmost field, another ESCAPE takes
you back to the previous screen.
If you do not wish to continue a function, you can abort the session by
escaping to the leftmost field, and then issuing another ESCAPE. Escaping a
function takes the analyzer back to the previous screen, or to the ANALYZE
Function, depending on the function escaped.
