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 T200H/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.
