Adjusting the Tension of the Coarse

Adjustment Knob

# Be sure to use the coarse tension adjustment ring @ to adjust the

tension of the control adjustment knob.

How to adjust the tension

Turn the coarse tension adjustment ring @ with your fingers or using a

flat-head screwdriver. Turning the ring in the direction of the arrow in-

creases the tension of the coarse adjustment knob, and 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 the focus using the fine

adjustment knob, it means that the tension of coarse adjustment knob is

too low. Turn the ring in the direction of the arrow to increase the tension.
