3. Operating Instructions
3.1 Specimen Placement and Stage Control
The microscope features a double-layer mechanical stage with 1.0mm stage divisions, allowing for precise manipulation of your specimen slides along the X- and Y-axis. This ensures accurate positioning and the ability to return to specific locations on the slide.
- Place your prepared slide onto the mechanical stage, securing it with the stage clips.
- Use the coaxial mechanical stage adjustment handle to move the slide horizontally and vertically, centering the area of interest under the objective lens.

3.2 Magnification and Objective Lenses
This microscope offers a magnification range from 40X to 2500X. It is equipped with four achromatic objective lenses:
- 4X Objective: For initial scanning and wide field of view.
- 10X Objective: For general observation.
- 40X(s) Objective: For higher magnification, spring-loaded to prevent slide damage.
- 100X(Spring Oil) Objective: For highest magnification, requires immersion oil for optimal clarity.
Rotate the revolving nosepiece to select the desired objective lens. Always start with the lowest magnification (4X) and gradually increase as needed.

3.3 Focusing
The microscope features separate coarse and fine focus knobs for precise focusing.
- Use the coarse focus knob for large adjustments to bring the specimen into approximate focus.
- Use the fine focus knob for small, precise adjustments to achieve sharp image clarity.

3.4 Illumination Control
The microscope utilizes LED illumination with a 1.25 NA Abbe condenser and iris diaphragm for clear examination and light control.
- Adjust the LED intensity using the dimmer control to achieve optimal brightness for your specimen.
- Use the iris diaphragm lever on the Abbe condenser to control the amount of light passing through the specimen, enhancing contrast and resolution.

3.5 Using the LCD Screen and E-Eyepiece
The 7-inch LCD display provides a larger field of view directly from the screen, allowing for easier observation and sharing without an external display. The 5MP E-eyepiece captures high-resolution images.
- Ensure the LCD screen is powered on and connected to the trinocular port.
- Adjust the screen's angle for comfortable viewing.
- For capturing still photos and videos, a video capture card is required (not included).

4. Maintenance
Proper maintenance will ensure the longevity and optimal performance of your Vabiooth microscope.
- Cleaning: Use a soft, lint-free cloth to clean the exterior of the microscope. For optical components (lenses, eyepieces), use specialized lens cleaning solution and lens paper. Avoid touching optical surfaces with bare hands.
- Storage: When not in use, store the microscope in its aluminum carry case to protect it from dust, moisture, and physical damage. Ensure all components are dry before storage.
- Handling: Always carry the microscope by its main body, supporting the base. Avoid sudden movements or impacts.
- Oil Immersion: After using the 100X oil immersion objective, always clean the objective lens and the slide thoroughly with lens paper and cleaning solution to remove all traces of immersion oil.
5. Troubleshooting
This section addresses common issues you might encounter with your microscope.
| Problem | Possible Cause | Solution |
|---|---|---|
| No image visible | Light source off; diaphragm closed; objective not in place; focus too far off. | Turn on light; open diaphragm; rotate objective into click stop; adjust focus knobs. |
| Image blurry/unclear | Improper focus; dirty lenses; air bubbles in oil (100X objective). | Use fine focus; clean lenses; reapply oil and remove bubbles. |
| LCD screen not displaying | Power issue; loose connection. | Check power adapter and cable connections. Ensure screen is turned on. |
| Cannot change screen language | Incorrect button sequence. | Refer to Section 2.3 and Video 1 for detailed instructions. |
