OPERATION
(continued)
Adjusting the Diopter & Focus
(Fig. 14)
Set the dioptor rings
of both eyepieces to “0” position.
(Do this when users change, because different users
will have different diopter settings.)
Place an easy-to-observe specimen on the stage plate,
i.e., a coin.
Rotate the zoom knob
to the highest magnification, then
turn the focusing knob
to focus the specimen.
Rotate the zoom knob
to the lowest magnification,
looking only into the left eyepiece, adjust the diopter
ring on left eyepiece to focus the specimen.
Repeat procedure for the right eyepiece.
Adjusting Interpupillary Distance
(Fig. 15)
To adjust the interpupillary distance, hold the left and
right eyetubes while observing a specimen. Rotate the
eyetubes around the central axis until the fields of view
of both eyetubes coincide completely. A complete circle
should be seen in the viewing field when viewing the
specimen slide. An improper adjustment will cause
operator fatigue and will disrupt the objective
parfocality.
Adjusting the Viewing Angle
(Fig. 16)
To adjust the viewing angle, hold the eyepiece tubes
with both hands and move them up or down to the
position that feels most comfortable.
The angle can be adjusted from 5° to 45°.
