Adjusting the Tension of the Coarse
Adjustment Knob
(Fig. 19)
# Be sure to use the coarse tension adjustment ring @ to adjust the
tension of the coarse adjustment knob.
How to adjust the tension
Turn the coarse tension adjustment ring @ with your fingers or using a
flat-head screwdriver. When the ring is turned in the direction of the arrow,
tension of the coarse adjustment knob increases. Turning the ring in the
opposite direction decreases the tension.
If the revolving nosepiece descends on its own or if the specimen gets
out of focus quickly even when brought into focus using the fine adjust-
ment knob, it means that the tension of the coarse adjustment knob is
too low. Turn the ring in the direction of the arrow to increase the tension.
