Adjusting the Focus

The coarse adjustment knob @ and fine adjustment knob ² are de-

signed to raise the stage (i.e. to let the specimen approach the objective)

when they are rotated in the direction of the arrows.

Replacing the Fine Adjustment Knob

# The fine adjustment knob has been attached on the right side at the

factory.

}The fine adjustment knob is designed detachable to prevent interference

with hand during manipulation of the stage feed knobs. Usually attach

the knob on the opposite side to the stage feed knobs.

1. Loosen the clamping screw @ using the Allen screwdriver, and remove

the fine adjustment knob ².

2. Remove the seal from the fine adjustment knob screw hole on the other

side and attach the knob by reversing the removal procedure.

3. Attach one of the provided seals on the screw hole | of the removed

fine adjustment knob.

}The fine adjustment dial ³ can be operated with your fingertip or finger

surface.

# The rotation tension of the coarse adjustment knob should be ad-

justed using the tension adjustment ring.

The coarse adjustment knob tension is preadjusted for easy use. How-

ever, if desired, you can change the tension using the tension adjust-

ment ring @. Turning the ring in the direction of the arrow increases

tension, and vice versa.

The tension is too low if the objective drops by itself or focus is quickly

lost after adjustment with the fine adjustment knob. In this case, turn the

ring in the direction of the arrow to increase tension.
