3. Open the Spectrometer expander, select the grating and set the center wavelength
to 435.8 nm if using a mercury lamp or to 0.0 nm if using a broadband source.
4. Set the slit to 25
(near full-scale) signal intensity.
5. Make sure that the spectroscopy-mount adapter moves freely at the spectrograph.
6. Select Align Spectrometer... from the Experiment Options menu. Review the
displayed information and then click on the Begin button. Typically, this feature
creates three 1-row high ROIs (one near the top of the array, one in the middle, and
one near the bottom) and begins data acquisition. Data will be continuously
acquired and displayed but will not be stored. See

NOTE:
Overhead fluorescent lights produce a mercury spectrum.
Use a white card tilted at 45 degrees in front of the entrance
slit to reflect overhead light into the spectrograph. Select
435.833 as the spectral line.
