Operation
A. Starting Up
1. Before using the microscope, adjust the light intensity control (20) to minimum position. This
should be repeated every time the microscope is switched on or off to prolong the use of the
bulb.
2. Switch to position ON. (Fig. 4)
3. Turn illumination control until the image is illuminated.
4. Light intensity must be adjusted according to the objective used (5), or the type of
preparation to be observed.
B. Interpupilliary adjustment of head.
1. Look through the eyepieces (1) move the eyepiece holder tubes (13) by rotating them on
their axis.
2. When the field of vision is complete through both eyepieces, ie. that the two images unify
into one, interpupilliary distance is correct.
3. Each person may have to adjust interpupilliary distance to receive the same image.
C. Focussing the microscope.
1. Rotate the nosepiece (3) and place the 10X objective (5) in the optical path, making sure
that it correctly clicks into place.
2. Rotate the coarse focus knob (16) until the stage (8) rests in its lowest position.
3. Place a microscopic sample on the stage, make sure the cover slip faces upwards.
4. Swing the moveable finger (4) on the mechanism (6), support the slide against the side
holder (7) and gently release the moveable finger, until the slide is well supported.
5. Ensure that the sample on the slide is in the optical path, to do so, move the stage using the
knobs controlling the X/Y movement of the stage. (18).
6. Looking through the eyepiece (1), turn the coarse focus knob until the preparation appears
in focus.
7. Readjust the focus with the fine focus knob (19) until the image appears sharply defined.
D. Adjusting diopter for differences in eyesight.
1. With your right eye, look into the right eyepiece tube (1) and adjust the sharpness of the
image using the fine focus knob (19).
2. With your left eye, looking through the left eyepiece, adjust the focus by rotating the diopter
corrector (2) on the left hand eyepiece tube until the image is sharp. Do not use the fine
focus knob.
