Wavelength Calibration
Measures the TLS wavelength accuracy against a physical standard. The dif-
ferences between the gas cell and the TLS are applied in the firmware.
When the message TLS Settle: xxxm (located in the lower right of the
display) turns from green to either yellow or red, then initiating a User Wave-
length Calibration will also perform a Lambda Zero. If a User Wavelength Cali-
bration is initiated when the message is green, then only a Wavelength
Calibration will be performed. The Lamda Zero process takes approximately
two minutes and the Wavelength Calibration takes approximately 1.5 minutes.
Refer to "Status Reporting for Laser Wavelength Zeroing" on page 3-13 and to
"Performing a User Wavelength Calibration" on page 3-17.
