Set the Pass Count Preset to 1000, then click OK.
10) Clear and start
!
Click Clear, then Start.

This time the pass count should go to 1000, and there should be 1000 counts in every
channel. Click the Auto button to scale the data in the Expanded Display Window.
11) Reduce the horizontal scale to 62
!
In the sidebar, click the down arrow beside the Horiz field until the value is 62. This
zooms in on the data so that there are only 62 data points displayed across the screen.
!
Notice that the full display in the corner still displays the entire spectrum. The part of the
full display visible in the expanded display has the same color background as the
expanded display, while the rest of the spectrum has a different color background.
12) Point and Click in the Full Display Window and click
This causes the expanded display to move to the area pointed to in the full display. Note
that the marker channel changes at the bottom of the screen. Try it a few times.
13) Point and Click in the Expanded View and click
This moves the marker channel in the expanded display and changes the marker
information at the bottom of the screen.
14) Highlight a range of channels
!
Click somewhere in the expanded display.
!
Click and drag to the left or right across the spectrum. Note that the marker width
increases as you continue dragging the mouse across the screen.
!
When you release the mouse button, this set of channels stays highlighted. You can now
manipulate this block of channels, such as marking them as a region of interest (ROI); or
calculating their centroid, gross area and net area.
15) Use the Data Info command from the Calculate menu
!
Click the Calculate menu and select Data Info.
!
Notice that the Marker Information Line at the bottom of the screen is now reporting a
centroid, gross area, and net area for the set of channels you just highlighted. (Since the
spectrum is flat, the centroid and net area aren’t very exciting.)
