A magnification can be preset by either clicking Mag.Preset Setup on the Setup menu,
clicking the
button above the Preset button, or right-clicking the Preset button.
NOTICE: If the preset magnification is lower than the minimum possible magnification for the
current WD value, the magnification is set to the minimum value.
