Replacing the Fine Adjustment Knob

The fine adjustment knob has been attached on the right side

CAUTION

at the factory.

} The fine adjustment knob is designed detachable to prevent interference

with hand during manipulation of the X-and Y-axis knobs.

Usually attach the knob on the opposite side to the X- and Y-axis

knobs.

1. Using the Allen screwdriver, loosen the clamping screw @ 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 a provided seal on the screw hole | of the removed fine adjustment

knob 3.

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

surface at the same time as manipulating the X- and Y-axis knobs.

Adjusting the Coarse Adjustment Knob Tension

Adjust the coarse adjustment knob tension using the tension

CAUTION

adjustment ring @.

The coarse adjustment knob tension is preadjusted for easy use. However,

if desired, you can change the tension using the tension adjustment ring

@. Turning the ring in the direction of the arrow increases tension, and

vice versa.

The tension is too low if the stage drops by itself of focus is quickly lost

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

Fig. 22 in the direction of the arrow to increase tension.

Pre-focusing Lever

} The pre-focusing lever ensures that the objective does not come in contact

with the specimen and simplifies focusing.

After focusing on the specimen with the coarse adjustment knob, turn this

lever @ in the direction of the arrow and lock; the upper limit on coarse

adjustment movement is set at the locked position.

After changing a specimen, approximate refocusing is easily accomplis-

hed by rotating the coarse adjustment knob to reach the pre-focused

position. After this, all you have to do is make fine adjustments with the

fine adjustment knob.

} Stage movement with the fine adjustment knob is not locked.

When the pre-focusing lever is locked, a coarse movement stro-

ke is reduced due to the microscope's mechanism, causing the

stage not to be able to be lowered to the lower limit. To lower

the stage to the lower limit, release the pre-focusing lever.
