6. 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 key 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 key will re-appear.
6.1. OVERVIEW OF OPERATING MODES
The M200EH/EM 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 iDAS 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.
