Change the magnification in order to adjust the observation position for the specimen.
Although the specific magnification to be used depends on the size of the specimen, a
magnification of 100x or less is generally suitable for adjusting the specimen position.
Changing the magnification from a low to high levels narrows the FOV and at the same time
changes the brightness, contrast, and focus. If changing the magnification makes the
performance of observation difficult, appropriately operate the various auto buttons (Auto B/C
(see 4.2.8 2. ), auto focusing (see (4.2.9 2. ) or manual adjustments to set conditions that
facilitate observation.
Manual adjustments on focusing can also be performed by using the mouse. For those, see
Sections 4.2.13 1. to 2. .
