If the AFM value still cannot be adjusted to 0 after the above checks, try to adjust the
mirror position according to Chapter 8, "MAINTENANCE." If you cannot adjust it
correctly, the cantilever itself may be bent or broken. Check the cantilever storage
condition according to Chapter 8, "MAINTENANCE." If all these attempts are
unsuccessful, replace the cantilever.

Approaching
1.
Using the Coarse Stage function of the SPM software, confirm that the stage
is positioned within the range for approaching.
For the confirmation procedure, refer to Section 5.3.5, “Checking the Stage
Position.”
2.
Watching the distance between the cantilever and the specimen using the
optional optical microscope, turn the manual approach thumbscrew so that
this distance becomes about 0.3 mm or less.
This completes the preparation for AFM observation.
