2. Clicking the Preset Button
Figure 4.2.12-2 Setting a Magnification (Operating the Preset Button)
By registering magnifications (two magnifications can be registered) that facilitate the finding
of an observation position or a magnification that is frequently used, the target magnification
can be set by simply clicking the Preset button. (For a description of how to set a Preset
magnification, see Section 4.3.33 Preset Magnification Window.)
NOTE : If two magnifications with a large magnification difference, such as a low
magnification (for example, x100 or less) or a high magnification (for example,
x10000 or higher) are set and switching is made between them, an observation
FOV deviation can occur. In such a case, change magnifications by using the
observation magnification button. Hitachi recommends that the Preset button is
used at x5,000 or less.
3. Selecting a Magnification from the View Menu Select a magnification from Preset
magnification values on the View menu. The current magnification changes to the selected
magnification.
