Factory Wavelength Cal Date
Shows the date of the last factory-performed wavelength calibration.
User Wavelength Cal Date
Shows the date of the last successful user-performed wavelength calibration.
Signal Source
Select either an external single wavelength signal source or the internal cali-
brator as the wavelength calibration source.
Wavelength Referenced In (for external calibration source only)
Selects air or vacuum for the calibration. If the internal calibrator is selected,
this selection will not be available.
Set Calibration Wavelength (for external calibration source only)
This is the exact wavelength of the calibration source that will be used for the
next user wavelength calibration. The wavelength entered must be within
2.5 nm of the wavelength measured using the factory calibration. If the inter-
nal calibrator is selected, this selection will not be available.

If you are using an external calibration source, enter the signal source and
wavelength of the calibration signal and whether the calibration is referenced
in air or vacuum. If you are using an internal calibration source, continue with
Step 5.
