This will bring up the Service Check dialog box, the diagnostic utility of the
device driver software. Choose the menu command Beam position /
Halogen lamp to open the shutter.
3. Adjust the holder by adjusting the stop bolt (2 in Fig. 18-3) so that the beam
transmits the center of entrance window on the polychromator side. To
make the beam position visible, use a white screen, e.g. a strip of paper.
4. For the adjustment of the holder in W position, put a planar mirror onto the
contact plate (3 in Fig. 18-3).
5. Adjust the unit by turning stop bold (5 in Fig. 18-3).
6. The fine adjustment is made by way of an energy measurement. Create a
measurement parameter file using the parameters described in Section
"Alignment of accessories", p.9.
7. First change the adjustment in the V position until the energy value has
reached its maximum size. Do the same in the W position.
The attachment has been adjusted.
