Keypad 

The row of eight keys just below the Vacuum Florescent Display are the main 
method by which the user interacts with the analyzer.  These keys are context 

sensitive and are dynamically re-defined as the user moves around in the software 
menu structure. 

Front Panel States LED’s 

There are three status LED’s located in the upper right corner of the Model 300E’s 
Front Panel.

10.5. Software Operation 

The Model 300E Gas Filter Correlation Carbon Monoxide Analyzer is at its heart a 

high performance, 386-based microcomputer running MS-DOS. Inside the DOS 

shell, special software developed by T-API interprets user commands vie the 
various interfaces, performs procedures and tasks, stores data in the CPU’s various 

memory devices and calculates the concentration of the sample gas.
