Adjusting the Brightness
Connect the power supply and turn on the main
switch.
Turn the brightness adjustment knob (see Controls
Diagram, p. 10) counterclockwise to increase the
brightness; turn it clockwise to decrease the
brightness.
Adjusting the Focusing Tension
The tension of the coarse focusing knob has already
been factory adjusted. If the handle is very heavy
when focusing or the specimen leaves the focus
plane after focusing or the stage lowers by itself,
adjust the tension adjustment collar (Fig. 10)
.
Adjusting the Interpupillary Distance
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.
Where
“·”
on the eyepiece tube lines up, then that is
the number for the interpupillary distance (IPD).

(Fig. 11).
Remember your interpupillary for future operation.
Adjusting the Focus
To ensure that you obtain sharp images with both eyes
(since individual eyes vary, especially for those
wearing glasses) any eyesight variation can be
corrected in the following manner: set both diopter
collars to “0”. Using your left eye only and the 10X
objective, focus your specimen by adjusting the coarse
adjustment knob
①
. When the image is in view, refine
the image to its sharpest focus by turning the fine
adjustment knob
②
. Rotate the diopter collar to obtain
the sharpest focus. To obtain the same sharp image
using your right eye, do not touch the coarse or fine
adjustments. Instead, rotate the right diopter collar
until the sharpest image appears. Repeat several
times to check.
NOTE:
do not counter rotate the
focusing knob as this will cause damage to the
focusing system.
