OPERATING YOUR CM300 MICROSCOPE
Once you have assembled your microscope, learned the terminology and purpose of each
component of the microscope, use of the microscope is simple and enjoyable. By following
these easy steps, you will be able to begin studying the specimen quickly and easily:
1. Plug the power cord into a regular 120V wall outlet. When using CM303 or
CM304 models allow time for LED to charge before use.
2. Secure the slide on the stage using the spring loaded finger clips. Make sure
the specimen is located over the aperture opening on the stage and directly
under the objective lens.
3. Rotate the nosepiece to lowest power objective (4XD). Be sure the objective
“clicks” into position.
4. Open disc diaphragm to its largest aperture to allow for the greatest contrast
and even dispersion of light.
5. Looking through the eyepiece, use the coarse focus know to bring the
specimen into focus. This should be done slowly and carefully. Use fine focus
knob to complete focus and provide sharpest image.
6. Higher magnification objectives are ready for use. The CM300 objectives are
parfocalized and once set at lowest objective (4XD), only slight turn of the fine
focusing knob is required when changing to 10XD, 40XRD and 100XRD
(CM302 and CM04 models).
For use with Mechanical Stage:
1. Using the finger clip lever, open the finger clip and place the slide along the
back edge of the mechanical stage. Slowly release the finger clip lever to
keep the slide in place.
2. Align the slide under the objective lenses. Use the High Drive Mechanical
Stage Controls to adjust slide position. The closest knob moves the slide East
to West (right/left) while the furthest knob adjusts the slide North to South
(back/front).
4. For best view of specimen, rotate the nosepiece to lowest power objective
(4XD). Be sure the objective “clicks” into position.
5. Looking through the eyepiece, use the coarse focus know to bring the
specimen into focus. This should be done slowly and carefully. Use fine focus
knob to complete focus and provide sharpest image.
