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., 0.7 x 10=7x)
NOTE: If using the optional auxiliary 0.5x
objective, then the above magnification would be
multiplied by auxiliary objective magnification.
(i.e., auxiliary 0.5 x 7=3.5x)
