PRECAUTIONS

•
When you move the tip close to the specimen using the Coarse Stage
window, the tip never stops even if a tunneling current or atomic force is
actually detected.
•
The specimen stub is gold-plated. Be careful not to scratch the stub
surface.
•
Insert or remove the specimen stub horizontally with care.
If an excessive force is applied to the scanner holder, the scanner inside it might be
damaged.
•
Do not turn off the power while the WinSPM software is running.
The software may be damaged if the power is turned off.
•
In order to prevent the tip from colliding with the specimen surface, the
speed of the tip movement must not be faster than 200 nm/s.
•
Upon completion of observation, turn off the computer after terminating
the software. Wait 10 seconds or more before restarting the computer.
•
The software must be terminated before the power is turned off. Never
turn off the power while the software is in operation.
•
To turn off the power of the SPM CONTROL system, first turn off the
LD-ON switch of the AFM AMP and then turn off the power of the SPM
CONTROL system.
The laser luminescence part may be damaged.
•
When you select and use a short cantilever out of two cantilevers, long
and short, be sure to remove the long one with a pair of tweezers.
Otherwise, the top of the long cantilever touches the specimen before the short one
does.
•
Be sure to insert the cantilever along with the groove.
Otherwise, the cantilever may be damaged due to an excessive force being applied
when the spring retainer is released.
•
Never touch the area around the cantilever on the cantilever holder with
bare fingers.
If that part is contaminated with hand grease, that might give rise to insufficient in-
sulation, thus possibly causing tunneling current leakage or incorrect operation of
the piezoelectric element.
•
Push the spring retainer vertically.
If you force it diagonally, the ceramic might be damaged.
•
When applying conductive paste to the cantilever and the cantilever
holder, be sure not to apply the conductive paste to the cantilever piezo-
electric element. When replacing a cantilever, be sure to confirm that no
previously used conductive paste remains on the holder.
Otherwise, the cantilever will tilt, causing the reflected laser beam not to irradiate
the right position.
•
Cantilevers must be stored in a desiccator when they are not in use.
If they are stored at high humidity, the cantilevers could bend, causing the reflected
laser beam not to reach the correct position. Especially, a gold-coated Si

cantile-
ver is prone to deteriorate with humidity.
