Focus Adjustment
Adjusting the Rotation Tension of the
Focus Adjustment Knob (Fig. 8, Fig. 9)
To adjust tension, hold
both left and right focus
adjustment knobs
①
with both hands, hold the
left knob (to prevent it from turning), and rotate
the right knob clockwise to increase (tighten) or
counterclockwise to decrease (loosen) the focus
knob tension.
After tension adjustment has been completed,
always rotate both adjustment knobs in the
same direction.
Changing the Magnification
The zooming knobs located on both sides of the
zooming body will change the magnification of
the specimen image.
Total Magnification =
Magnification of zoom
body x magnification of eyepiece
(i.e., 0.8 x 10=8x)
NOTE:
If using any of the optional auxiliary
objectives, then the above magnification would
be multiplied by auxiliary objective magnification.
(i.e., auxiliary 0.5 x 8=4x)
Moving the Microscope (Fig. 10)
Before moving the microscope, be sure to
remove any slide/samples. When moving the
microscope, hold the stand and base as shown
