Engaging and Disengaging the Zooming
2
Knob Click Stop Function
}When the click stop knob is set to ON, the click stop function is en-
gaged for each magnification indicated with the zooming knob. When
the knob is set to OFF, the zoom magnification can be varied continu-
ously 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 9 intermediate indication posi-
tions between 0.63X and 6.3X 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
}Adjusting the aperture iris diaphragm increases the contrast of the ob-
served image as well as the depth of focus.
However, setting the aperture iris diaphragm too narrowly degrades reso-
lution.
1. Adjust the aperture iris diaphragm ring @ to the left or right.
Rotating the ring toward the left (\) opens the aperture; rotating it to-
ward 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 illumina-
tor (SZX2-ILLC10), minimizing the aperture may obscure a part of the
observed field of view. In this case, open the aperture to an interme-
diate position.

Zoom Magnification Indication
The body zoom magnification is indicated on the zooming knob on the
right side.
The total magnification of observation can be calculated with the follow-
ing formula:

objective cannot be used.
