NOTES

The flow charts appearing in this 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.

6.1. Overview of Operating modes

The GFC 7000TA 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 CO2 concentration is displayed 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.

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 SET UP mode is also used for performing various diagnostic tests during troubleshooting.
