Engaging and Disengaging the Zooming
Knob Click Stop Function
(Fig. 5)
}When the click stop knob is set to ON, the click stop function is engaged
for each magnification indicated with the zooming knob. When the knob
is set to OFF, the zoom magnification can be varied continuously and
finely near the click groove.
The click stop knob has been set to OFF before the microscope is shipped
from the factory.
}A click stop is provided for each of the 12 intermediate indication positions
of the zoom microscope body.
1. To engage the click stop function, rotate the click stop ON-OFF screw @
fully clockwise (in the direction of the arrow) using the Allen screwdriver.
The zooming knob then stops at every position corresponding to the
magnification indicated on the zoom magnification indication ².
2. To disengage the click stop function, rotate the click stop ON-OFF screw
@ fully by three turns from the ON position, in the direction opposite to
the arrow, using the Allen screwdriver.
# Do not rotate the screw too much, or the cover may be damaged.

Adjusting the Aperture Iris Diaphragm
(Fig. 6)
}Adjusting the aperture iris diaphragm increases the contrast of the
observed image as well as the depth of focus.
However, setting the aperture iris diaphragm too narrowly degrades
resolution.
1. Adjust the aperture iris diaphragm ring @ to the left or right.
Rotating the ring toward the left (\) opens the aperture; rotating it toward
the right ( ) closes it. Adjust while monitoring the observed image to
confirm the contrast and focal depth improvement effects.
# Do not close the aperture too much, for this may cause degradation
in resolution and/or lack of ambient light.
2. Use the scale gradations as references for memorizing the ring position.
# When the microscope is combined with the coaxial vertical illuminator
(SZX2-ILLC16), minimizing the aperture may obscure a part of the
observed field of view. In this case, open the aperture to an intermediate
position.
