6. Operating Instructions
6.1 Power On/Off
Press and hold the power button on the microscope unit to turn it on or off. The screen will illuminate upon startup.
6.2 Lens Switching and Focusing
The TriL110 features three distinct lenses for various magnification needs:
- 1000X Lens (2X-1000X Magnification): Ideal for observing entire coins, stamps, and larger objects. Object distance: 8mm-500mm.
- 1500X Lens (10X-1500X Magnification): Suitable for intricate tasks like PCB soldering and watch repair, offering a larger working distance. Object distance: 38mm-180mm.
- 2500X Lens (2000X-2500X Magnification): Designed for microscopic details, such as biological slides and mites. Object distance: 3mm-4mm. Note: For optimal focus with the 2500X lens, the lens needs to be very close to the object.
To switch lenses, simply rotate the lens barrel until the desired lens clicks into position. Adjust the distance between the object and the microscope lens, then rotate the focus wheel to achieve a clear image on the HD IPS screen.
6.3 Lighting System
The microscope is equipped with a comprehensive lighting system:
- 12 Built-in LED Main Lights: Provide illumination from around the lens.
- 2 Gooseneck Side Lights: Adjustable lights for angled illumination, useful for reducing glare or highlighting textures.
- Bottom Slide Light: For observing transparent or translucent specimens, such as biological slides.
All lights can be dimmed and charged independently. Use the dedicated controls on the microscope or remote to adjust brightness.

6.4 Photo and Video Recording
The microscope supports 24MP photo capture and 2K video recording. Use the buttons on the unit or the wireless remote control to switch between photo and video modes and to initiate capture.

6.5 HDMI & USB Output
Connect the microscope to an external display (monitor, TV) via HDMI or to a computer via USB for a larger view or data transfer. This allows for real-time sharing and detailed analysis.

6.6 Wireless Remote Control
The included wireless remote control allows for convenient operation without disturbing the microscope or sample. Functions include adjusting magnification, capturing photos, and recording videos.
6.7 Specific Lens Applications
6.7.1 Coin Observation (1000X Lens)
The 1000X lens is optimized for viewing entire coins, from small dimes to large dollar coins, thanks to the taller 12.6-inch stand and larger 7x8-inch base. This provides ample space for coin collection and detailed examination.

6.7.2 Soldering and Repair (1500X Lens)
The 1500X lens provides high magnification suitable for intricate soldering tasks, watch repair, and examining small electronic components. Its design ensures a stable and spacious work area.

7. Maintenance
- Cleaning Lenses: Use a soft, lint-free cloth specifically designed for optical lenses. For stubborn smudges, a small amount of lens cleaning solution can be applied to the cloth, not directly to the lens.
- Cleaning Screen: Wipe the screen gently with a microfiber cloth. Avoid abrasive cleaners.
- General Cleaning: Use a dry, soft cloth to wipe the body of the microscope. Do not use harsh chemicals or solvents.
- Storage: Store the microscope in a cool, dry place, away from direct sunlight and extreme temperatures. When not in use for extended periods, remove the SD card and ensure the battery is partially charged.
- Battery Care: The microscope contains a Lithium Ion battery. Avoid fully discharging the battery frequently. Charge it regularly, even if not in use, to maintain battery health.
