Figure 5-1: The Background Spectrum
NOTE: If the background spectrum is too noisy, repeat this operation
and increase the number of scans to be averaged using the field that is
adjacent to the scan button. If the background scan is an averaged
scan, it is common practice (but not necessary) to use the same
number of scans for the collection of the transmission spectrum.
d) After you have obtained a suitable background spectrum, use the
key to move it into Register 1 in the PlotLegend dialog box (Figure 5-2).

NOTE: If you are collecting data on a continuous basis or on a timed
basis, the Stop button can be used to stop the operation.
