4. OVERVIEW OF OPERATING MODES
To assist in navigating the analyzer’s software, a series of menu trees can be found 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 T300/T300M 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
CO concentration can be viewed on the front panel and output as an analog voltage from
rear panel terminals, calibrations can be performed and TEST functions and WARNING
messages can be examined. If the analyzer is configured to measure a second gas (e.g.
CO along with O
2
or CO
2
) the display will show a readout of both concentrations.
The second most important operating mode is SETUP mode. This mode is used for
performing certain configuration operations, 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.
