Operation
A. Starting Up.
1. Before using the microscope, adjust the light intensity
control (23) to minimum position. This should be
repeated every time the microscope is switched on
or off to prolong the use of the bulb.
2. Press switch to position ON. (Fig. 1)
3. Rotate light intensity dial until the image is
illuminated.
4. Light intensity should be adjusted in accordance
with the objective used, or the type of specimen
examined.
B. Interpupillary Adjustment. (Only in binocular models)
1. Look through the eyepiece (1) and adjust the distance between the eyepiece tubes (14) by
grasping the head (15), by its four gripped corners (13), and moving inwards or outwards.
2. When a full field of view is observed through both lenses, and images blend into one, the
interpupillary distance is correct for the user's eyes. Take note of the index reading marked
in the interpupillary scale (2) for the following step.
3. Adjust the diopter scales (14) situated on both eyepiece tubes until the reading of both
scales coincides with the value of the interpupillary distance scale. This step is necessary to
maintain the parfocality of the objectives.
4. Variation in interpupillary distance, necessitates the readjustment of the diopter scales.
C. Focusing the microscope.
1. Revolve the nosepiece (3) to place the objective 4X (4) in the optical path, checking that it is
clicked into place.
2. Turn the coarse focusing knob (19) until the stage (8) is set to its lowest position.
3. Place the microscopic specimen slide on the stage, making sure that the cover slip is raised.
•
Swing out the moveable stage clip (5) on the mechanical specimen holder (6), support the
specimen slide against the fixed stage clip (7) and gently release the moveable clip until the
preparation is well fixed into place.
•
In the models 1801/2801: Raise the specimen holder clips by putting downward pressure on the
back part, slide the specimen slide under the clips, and release pressure so that the slide is well
fixed into place.
4. Insure that the specimen to be examined is in the optical path. To do so, adjust the knobs
controlling the X/Y movement of the stage (21). In the models 1801/2801 the specimen must
be moved manually.
5. Looking through the eyepiece (1), adjust the coarse focus knob until the specimen appears
in focus.
6. Readjust the focus with the fine focus knob (20) until the image appears in sharp focus.
