Eyepieces with eyepiece micrometer disk

1. Look through the eyepiece with eyepiece micrometer disk and rotate its

diopter adjustment rings ² to bring the micrometer scale into focus.

2. Place an easy-to-observe specimen on the stage plate.

3. Set the zoom adjustment knob ³ for low magnification, look through the

eyepiece with eyepiece micrometer disk and rotate the focus adjustment

knob | to bring the specimen into focus.

4. Set the zoom adjustment knob ³ for the highest magnification and

rotate the focus adjustment knob | to bring the specimen into focus.

5. Set the zoom adjustment knob ³ for the lowest magnification and rotate

the diopter adjustment ring ƒ of the eyepiece without eyepiece micrometer

disk, instead of the focus adjustment knob |, to bring the specimen into

focus.

}Note the left and right diopter scale values so that it can be quickly

duplicated in future observations.

Diopter scale of the 10X eyepieces

}The valid range of the diopter scale is between –8 and +5 but a slight

margin is added to it. Therefore, the diopter value may exceed +5 or –8

when it is adjusted to the maximum. In this case, whether the diopter

value is over +8 or under –5 can be identified by the length of the

eyepiece.

+ 5

Using the High/Low Zoom Magnification

Stopper

}The magnification can be limited in the desired range by setting each

stopper on the microscope body (also used as the magnification indices)

and the stopper ring on each zoom adjustment knob. The right zoom

adjustment knob is used to limit the higher end of the magnification, and

the left knob is used to limit the lower end.

1. Using an Allen wrench, loosen the clamping screw of the right stopper

ring @ and free it. (Also free the left knob in this way.)

2. Rotate the right zoom adjustment knob ² to align the desired higher-limit

magnification with the index (stopper) ³.

3. Gently apply the stopper ring @ to the stopper ³ and tighten the clamping

screw using the Allen wrench to retain this condition.

4. Set the left zoom adjustment knob according to the desired lower-limit

magnification by rotating the left knob and clamping the left stopper ring

in the same way as above.
