Clicking the Preset button changes the current magnification to the magnification that is display
on the button.
Set two preset magnifications to one that facilitates finding an observation position and one
to be used when saving the image. In this manner, switching to an intended magnification
can be accomplished simply by clicking the Preset button.
Set a preset magnification by using the Preset Magnification window (see 4.3.33).
NOTE : The low magnifications x20 and x25 are set only when the spacing between the
topmost surface of the specimen and the gauge is set to approximately 6 mm or
greater during the specimen stub adjustment (see 4.2.2 6.). If the spacing between
the topmost surface of the specimen and the gauge is 6 mm or less, the Preset
Magnification button cannot be switched by setting preset magnifications x20 or
x25. In reference to Section 4.3.32 Preset Magnification window, set a
magnification other than x20 or x25.
