Figure 4.2.3-6 Securing Specimen Stub Assembly
NOTE : Specimen stub assembly can be fixed with the hexagon socket head screw outside
of the holder base. The vibration trouble might occur when observing at high
magnification or observing the heavy specimen. Therefore, tighten the hexagon
socket head screw with the provided ball wrench 2 to fix the specimen stub
assembly. In that case, use the ball wrench 2 so that it does not touch the stage
feeding screw. When removing the specimen stub assembly, loosen the hexagon
socket head screw first, and remove it. Do not use the ball wrench other than the
provided ball wrench 2.
NOTICE: When bringing your hands close to the motion mechanism of the specimen
stage during specimen change, Be careful not to touch any moving parts, such
as gears and driving screws, and not to get your clothing caught.
