the Escape button in many cases also switches the analyzer back to the
Analyze function. Alternatively, if you leave your analyzer on MAIN
MENU screen within 5 seconds without touching any key, it will automati-
caly return to analyze function.
If the analyzer is in subfunction mode,
in most cases, it will automaticaly return to analyze mode within 10 min-
utes.
The Analyze function screen shows the impurity concentration and the
application gases in the first line, and the range in the second line. In the
lower right corner, the abbreviation
Anlz indicates that the analyzer is in the
Analyze mode. If there is an * before the
Anlz, it indicates that the range is
linearized.

n indicates non inverting range
i indicates inverting range
If the concentration detected is over range, the first line of the display
blinks continuously.
4.8 Programming
CAUTION: The programming functions of the Set Range and
Curve Algorithm screens are configured at the
factory to the users application specification. These
functions should only be reprogrammed by trained,
qualified personnel.
To program, you must:
1. Enter the password, if you are using the analyzer’s password
protection capability.
2. Connect a computer or computer terminal capable of sending an
RS-232 signal to the analyzer RS-232 connector. (See chapter 3
Installation for details). Send the rp command to the analyzer.
Now you will be able to select the APPLICATION and ALGO-
RITHM setup functions.
