Remount the Dimension Head
With the sample prepared and positioned on the stage, slowly remount the Dimension head in its
dovetailed, vertical mount.
Ideally, the Dimension head should come to rest in its mount at a level where the tip is just above
the level of the fluid. If the head rests too low in its mount, use either of the following methods to
raise the mount:
• Raise the mount further by using the Motor > Step Motor > Tip Up command.
• Remove the head from its mount and lower the sample into the fluid level. Remount the
head.
Note: Because the tip is lowered through a fluid layer, the laser beam will refract
slightly requiring minor adjustments. Refer to
Section 10.5.10 for more
information regarding aiming the laser through a fluid layer.
At this point, the fluid cell should be prepared for TappingMode imaging: the cantilever is aligned
with the laser, the sample is prepared and the tip is immersed in fluid and positioned one millimeter
above the sample surface. All that remains is to tune the cantilever.
Verify that the Microscope is Dry
Verify that all Dimension 3100 surfaces are free of spilled fluid. Wick away moisture and droplets
with filter paper.
CAUTION: If the fluid level is too high, the end of the scanner tube may be
dunked too far into fluid. Do not allow this to happen. Permanent
damage to the scanner tube may occur.
ATTENTION: Si le niveau du liquide est trop important, l’extrémité des
céramiques piézo-électriques peut tremper dans le liquide. Ceci ne
doit jamais arriver. Ce cas de figure peut entraîner des dommages
définitifs sur les céramiques piézo-électriques.
VORSICHT: Falls der Flüssigkeitsspiegel zu hoch ist, könnte das Ende des
Scannerröhrchens in die Flüssigkeit eintauchen-dies darf auf
keinen Fall passieren. Es könnte sonst eine dauerhafte Schädigung
des Scannerröhrchens eintreten.
