2 POINT ALIGNMENT Move crosshair to the edge of the bias ring and define as point “A.”
2 POINT ALIGNMENT Move to the other side of the detector and define point “B”at the outer edge of the bias ring.
2 POINT ALIGNMENT Pt B Pt A 2 point alignment adjusts small angular deviations such that the imaginary line that connects points A and B is parallel to the X axis of the probe station.

WARPING MEASURING Measure the warping by focusing on a position and take of the vacuum the adjusting z direction such that the component comes back into focus. Then measure the displacement in the z direction.
WARPING MEASURE Move to the other side of the detector and define point “B”at the outer edge of the bias ring.
