4. OPERATING INSTRUCTIONS
To assist in navigating the analyzer’s software, a series of menu trees can be found in
Appendix A of this manual.
Note The flow charts appearing in this section contain typical representations
of the analyzer’s display during the various operations being described.
These representations may differ slightly from the actual display of your
instrument.
The ENTR button may disappear if you select a setting that is invalid or
out of the allowable range for that parameter, such as trying to set the 24-
hour clock to 25:00:00. Once you adjust the setting to an allowable value,
the ENTR button will re-appear.
4.1. OVERVIEW OF OPERATING MODES
The 9110TH/M software has a variety of operating modes. Most commonly, the
analyzer will be operating in SAMPLE mode. In this mode, a continuous read-out of
the NO, NO
2
and NO
x
concentrations are displayed on the front panel and are available
to be output as analog signals from the analyzer’s rear panel terminals. Also,
calibrations can be performed, and TEST functions and WARNING messages can be
examined.
The second most important operating mode is SETUP mode. This mode is used for
performing certain configuration operations, such as for the DAS system, configuring
the reporting ranges, or the serial (RS-232/RS-485/Ethernet) communication channels.
The SET UP mode is also used for performing various diagnostic tests during
troubleshooting.
