3. Apply AC power. The analyzer performs a self test
visible only as a series of patterns on the screen.
The individual LCD display segments will light in
several patterns and finally all at the same time.
4. The screen will display the message shown in the
following illustration.
5. After the instrument has read the connected
sensors, the last five digits of their serial number
(S/N), the type, and the cell factor are shown. See
the following illustration.
6. If there are more sensors than can be shown on the
display, MORE (F1) will be visible. Press the
function key F1 to show these sensors.
7. Backlight each sensor listed and press ENTER (<––
l
)
to accept the addresses assigned to the sensors.
Use scrolling keypads to move backlight if you wish
to change the order of the sensor addresses being
assigned.
NOTE
If Diff/Ratio function is to be used, back-
light the sensor that is to be sensor #1
first, sensor #2 second. See background
information in
Section 4.4 .
8. On the REVIEW ADDR LIST screen, press ENTER
(<––

).
9. The analyzer is now operational!
10. Review the typical process display and keypad use
in Section 2.0 .
11. If Process display has any Alarms or ERR segments
showing, refer to Section 6.0 Diagnostics and
Troubleshooting.
