Inserting the cantilever holder
After attaching a cantilever to the cantilever holder, insert the cantilever holder into the
SPM head until it stops.

Affixing the specimen
To properly observe a surface potential image, it is essential that the specimen be tightly
secured to the specimen stub. Affix the specimen to the specimen stub with conductive
paste such as Dotite instead of conductive tape.
—— CAUTION ———————

holder, be sure no

Preparation before an approach
Before performing an approach, affix the specimen. Adjust the laser and photodiode;
then perform a coarse approach according to the procedure in Section 5.4.1, “Approach.”
