1-8 SOFTWARE/DISPLAYS
The User interface is an extensive menu struc-
ture. Three types of screens may appear on the
Front Panel Display:
• Measurement (Single or multiple
Analyzer displays)
• Menus
• Info (Help)
Figure 1-4. Measurement Display
The Measurement screen is the actual opera-
tional screen in which the measured component
concentration is shown. Up to four (five with
V2.3 software and higher) measurements can
be shown on the multiple Analyzer measure-
ment screen at once. If an Analyzer module has
lost communication with the network, the screen
will display "No Data."
From the Single Analyzer measurement screen
you can either select the menus by pressing the
“MENUS” softkey (or right arrow key), or you
can select a couple of screens that provide es-
sential information about the Analyzer. Access
these by pressing the “PARMS” (short for pa-
rameters) softkey.
The Menu screens include all of the data and
functions necessary to interrogate and operate
the Analyzer and I/O Modules. The selected
menu line is highlighted in inverse video. Use
the ↑ and ↓ keys to highlight the desired menu
line. Press the Enter (↵) key, and depending on
the item selected, one of the following will occur:
If the highlighted item ends with a colon and a
value on the right side of the display screen, the
item will become editable.
If the highlighted item ends with three dots (...),
Another menu will appear.
If the line ends with an exclamation point (!) it is
a function (information) line and is not editable
or executable, nothing will occur, and in fact you
will not be able to select it.
If the first of the above possibilities occurs, only
the right-hand portion of the menu line will then
be highlighted. Use the ↑ and ↓ keys to scroll
the data. Under certain circumstances, the cur-
sor is movable with the → and ← keys. This
allows you to edit specific characters within a
numerical or string (alphabetic) variable. Press
→ to start individual character editing, and then
→ or ← to select the character to edit: edit it
with the ↑ or ↓ keys. Press Enter (↵) when you
are done, or press the ESCAPE softkey to abort
the editing and return to the original value.
To escape from a menu, either press the left ar-
row key (←), the ESCAPE soft key, or to jump
all the way back to the Main menu, press the
HOME softkey.
