Setup Guide
Proper assembly and setup are crucial for optimal performance and longevity of your AmScope B120 Series microscope. Follow these steps carefully:
- Unpacking: Carefully remove all components from the packaging. Inspect for any damage during transit.
- Base Placement: Place the microscope base on a stable, level surface.
- Head Assembly: Gently insert the binocular head into the top port of the microscope body. Secure it with the set screw if provided.
- Eyepiece Installation: Insert the wide-field eyepieces (WF10x and WF25x) into the eyepiece tubes of the binocular head.
- Objective Lenses: Ensure the objective lenses (4x, 10x, 40x, 100x) are securely screwed into the revolving nosepiece.
- Power Connection: Connect the power cord to the microscope and then to a suitable electrical outlet (110 Volts AC).
- Camera Installation (if applicable): If using the 5MP USB camera, remove one eyepiece and insert the camera into the eyepiece tube. Connect the USB cable to your computer and install the provided software.



Operating Your Microscope
Once assembled, your AmScope B120 Series microscope is ready for use. Follow these instructions to begin your observations.
Powering On and Illumination
Locate the power switch and brightness control knob on the microscope base. Turn on the power and adjust the LED illumination to a comfortable level. The LED sub-stage lighting provides cool, energy-efficient, and daylight-balanced illumination for clear imaging.

Placing and Moving Specimens
Place your prepared specimen slide onto the mechanical stage. Use the stage clips to hold it securely. The 2-layer mechanical stage allows for smooth and precise movement of the slide using the X-Y axis control knobs, enabling you to scan the specimen area efficiently.

Adjusting Magnification
Rotate the revolving nosepiece to select the desired objective lens (4x, 10x, 40x, 100x). Combined with the WF10x and WF25x eyepieces, this provides magnification levels from 40X to 2500X. Always start with the lowest magnification (4x) for initial viewing and then switch to higher powers as needed.

Focusing
Use the coarse focus knob for large adjustments to bring the specimen into approximate focus. Then, use the fine focus knob for precise adjustments to achieve a sharp, clear image. Adjust the interpupillary distance of the binocular head to match your eyes for comfortable viewing.

Digital Camera Operation
For digital viewing and image capture, ensure the 5MP USB camera is correctly installed and connected to your computer. Launch the accompanying software. The software allows for live viewing of the microscopic image on your screen, capturing still images, and recording videos. Refer to the camera software's specific manual for detailed instructions on its features and analysis tools.
Maintenance and Care
Proper maintenance ensures the longevity and performance of your AmScope B120 Series microscope.
- Cleaning Lenses: Use only specialized lens cleaning paper and lens cleaning solution. Gently wipe objective lenses and eyepieces. Avoid touching optical surfaces with bare hands.
- Cleaning Body: Wipe the microscope body with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners.
- Storage: When not in use, cover the microscope with a dust cover to protect it from dust and debris. Store in a dry, cool place.
- Handling: Always carry the microscope by its arm and base. Avoid sudden impacts or vibrations.
- Electrical Safety: Disconnect power before cleaning or performing any maintenance.
