Model 9110TH NOx Analyzer

Overview of Operating Modes

4. OVERVIEW OF OPERATING MODES

To assist in navigating the analyzer’s software, a series of menu trees is available for reference in Appendix A of this manual.

Note

Some control buttons on the touch screen do not appear if they are not

 

applicable to the menu that you’re in, the task that you are performing, the

 

command you are attempting to send, or to incorrect settings input by the

 

user. For example, the ENTR button may disappear if you input 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.

The 9110T analyzer software has a variety of operating modes. The most common mode that the analyzer will be operating in is the SAMPLE mode. In this mode, a continuous read-out of the NOx concentrations can be viewed on the front panel and output as an analog voltage from rear panel terminals.

The second most important operating mode is SETUP mode. This mode is used for configuring the various sub systems of the analyzer such as for the DAS system, the reporting ranges, or the serial (RS-232 /RS-485 / Ethernet) communication channels. The SETUP mode is also used for performing various diagnostic tests during troubleshooting.

The mode field of the front panel display indicates to the user which operating mode the unit is currently running.

In addition to SAMPLE and SETUP, other modes the analyzer can be operated in are described in Table 7-1 below.
