4.3.16 Magnification Button

This button allows the user to change the observation magnification. To increase the
magnification from the current level, click the + side; to decrease it, click the – side. These
operations change the current magnification to a level one step above or below the current level,
and the image changes to the new magnification rate. The current magnification is displayed in
the center of the button.
Continuing the click the button causes the magnification to change successively either
upward or downward, one step at a time.
Observation magnification can also be adjusted by dragging the mouse on the magnification
operation button. See Section 4.2.12 Setting a Magnification 4. .

NOTE : The magnifications x20 and x25 displayed only when the spacing between the
topmost surface of the specimen and the gauge is set to approximately 6 mm or
greater, in consideration of the thickness of the specimen, when the height of the
specimen stub is adjusted (see 4.2.2 6. ). In other cases, these levels are not
displayed. Normally, the spacing between the topmost surface of the specimen
and the gauge should be set to 1 mm.
