A
DJUSTING THE MEASUREMENT PLANE
63
Ideally, the XY-plane of the scanner has already been correctly aligned with
the sample plane using the three Levelling screws on the Scan head. How-
ever, this alignment can not be performed once the automatic approach has
been done, because this will damage the tip. During measurement, the
measurement plane should therefore be adjusted electronically using the
parameters ‘X-Slope’ and ‘Y-Slope’.
Maladjusted slope: measurement with improperly set X*-slope
Slope: Sample’s and measurement orientation before slope adjustment
