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

Default XPS position
Theta angle 240°
x 21.5
y 26.0
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°)).
