Function Reference
Wavelength Line Mkr 1/2
User Wavelength Cal Date
Shows the date of the last successful user-performed wavelength calibration.
Signal Source
Selects either an external single wavelength signal source or the internal calibrator as the wave-
length 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 wave-
length calibration. The wavelength entered must be within 2.5 nm of the wavelength measured
using the factory calibration. If the internal calibrator is selected, this selection will not be avail-
able.
User Multipoint Wavelength Calibration Data
Selects either Offset or Replaced for the calibration data. Offset will adjust the user multipoint
data at all wavelengths to provide the best wavelength accuracy at the calibration source wave-
length.
Replaced will disable the multipoint data when used with an external source (select Offset to re-
enable).
Replaced will delete multipoint data when used with the internal calibrator.

Wavelength Line Mkr 1/2
Allows you to set the positions of the line markers. Wavelength Line Mkr 1 is always to the left of
Wavelength Line Mkr 2. When either one of the line markers is accessed, the reduced section of
the wavelength is highlighted in blue. The line marker can then be set to the desired position
using the knob, step keys, or numeric keypad. This limits the measurement range of the sweep
limit, search limit, and integrated power.
