4. BASIC OPERATION

The T803 analyzer is a computer-controlled analyzer with a dynamic menu
interface that allows all major operations to be controlled from the front panel
touchscreen through user-friendly menus (A complete set of menu trees is located
in Appendix A of this manual)
This section includes step-by-step instructions for using the display/touchscreen
to set up and operate the analyzer's basic CO2 and O2 measurement features and
functional modes.

4.1. OVERVIEW OF OPERATING MODES

The T803 software has several operating modes (Table 6-1), and most commonly
operates in SAMPLE mode. In this mode a continuous read-out of the gas
concentration is displayed on the front panel. SAMPLE mode is used to:
perform calibrations
run test functions
read and clear warning messages
output analog data (when enabled)
The next most commonly used operating mode is SETUP mode, which is used
to;
perform certain configuration operations, such as programming the DAS
system or the configurable analog output channels
set up the analyzer’s serial communication channels (RS-232, RS-485,
Ethernet)
perform various diagnostic tests during troubleshooting
