  1. Transfer the sample.
  2. Move the manipulator to the default position for XPS:

Default XPS position
Theta angle 240°
x 25.0
y 28.0
z 10.0
  1.  Verify sample position in camera view. Orange circle indicates analyzed area (~7 mm).

  1. Adjust Z-axis (vertical) position.
  2. Adjust horizontal position.
    1. X and Y must be moved almost simultaneosly. Change each single axis by no more than 1 mm.
    2. Per 1 mm of horizontal asjustment, move Y by 0.87 mm (sin(60°)) and X by -0.5 mm (-cos(60°)).

-1 24.5 28.9   1 25.5 27.1
-2 24.0 29.7   2 26.0 26.3
-3 23.5 30.6   3 26.5 25.4
-4 23.0 31.5   4 27.0 24.5
-5 22.5 32.3   5 27.5 23.7

  1. Lower X-ray gun to the red line on the linear transfer, approximately 8 mm from the bottom limit. (8 mm equals the width of wrench 7, which is often somewhere around.)
