The functions available at the main menu are described below.
R) Real Time TGA Program
Turns the TGA on and displays the real time screen. This is the normal operating mode. See section 3.4 for
additional information.
T) TGA on/off
Toggles the TGA on or off. When the TGA is on, all current and temperature controls are active and
concentration calculations are being made, but the real time screen is not displayed, and no data are saved
to the hard disk.
L) Laser on/off

operate the TGA100 without driving the laser. For example, the laser temperature may be monitored
during the initial cool down by disabling the laser at the main menu and then entering the real time screen.
P) Parameter Change Menu
Displays submenus for changing parameters. See section 3.5 for additional information.
M) Laser Mapping Menu
