3.
Set the slit to a minimum of 10 µm.
NOTE:
If necessary, adjust the Exposure Time to maintain optimum (i.e.,
near full-scale,) signal intensity.
4.
Wait until the detector locks at its default temperature.
NOTE:
When using an LN-cooled detector, fill the dewar after the
detector has been powered on.
5.
Turn on Focus mode.
6.
Perform the following procedure to adjust the rotation alignment:
a.
Use a 9/64” hex wrench to loosen the four (4) screws at the corners of the detector
mounting plate.
b.
While watching a live display of the spectrum displayed as a graph, select a peak to
monitor.
c.
Carefully, and slowly, rotate the detector. Up to 4 degrees of rotation is possible.
The width of the selected peak will vary from broad to narrow and back to broad.
The detector is propreraly aligned when it is set for the narrowest achievable width.
Two alternate methods for rotationally aligning the system are:
a.
Capture an image and display the horizontal and vertical cursor bars. Compare the
vertical cursor bar with the line shape on the screen. Rotate the detector until the
line shape on the screen is parallel with the vertical bar.
