Configuració
1. Desembalatge i col·locació:
Carefully remove all components from the packaging. Place the microscope on a stable, level surface away from direct sunlight, heat sources, and vibrations.
2. Head Assembly:
Loosen the set screw on the top of the microscope body. Gently insert the trinocular head into the opening, ensuring it is fully seated. Tighten the set screw to secure the head. The head can be rotated 360 degrees for comfortable viewing.
3. Eyepiece Installation:
Remove the protective caps from the eyepiece tubes on the trinocular head. Insert the two 10X widefield eyepieces into the tubes. If dust caps are present, remove them.
4. Objective Installation:
Rotate the revolving nosepiece until the lowest power objective (4X) is positioned over the stage opening. Screw the 4X, 10X, 40X, and 100X Plan Achromatic objectives into the nosepiece in increasing order of magnification. Ensure they are securely tightened.
5. Connexió d'alimentació:
Connect the power cord to the microscope's power input and then to a suitable electrical outlet (90-240V AC).

Instruccions de funcionament
1. Power On and Illumination:
Turn on the main power switch, usually located at the base of the microscope. Adjust the brightness control knob to achieve comfortable illumination. The Kohler illumination system provides even and bright lighting for optimal viewing.
2. Specimen Placement:
Col·loqueu el portaespècimens preparat sobre el suport mecànic.tage. Utilitzeu la stage clips to hold the slide securely in place. Use the X-Y stage control knobs to center the specimen area you wish to observe under the objective lens.
3. Enfocament:
- Enfocament aproximat: Begin with the 4X objective. Use the coarse focus knob to bring the specimen into approximate focus.
- Enfocament precís: Once roughly focused, use the fine focus knob for precise focusing. This knob allows for minute adjustments to achieve a sharp image.
- Interpupillary Distance and Diopter Adjustment: Adjust the interpupillary distance by moving the eyepiece tubes until a single, circular field of view is observed. If one eye requires a different focus, use the diopter adjustment ring on one of the eyepieces to compensate.
4. Changing Magnification:
To increase magnification, rotate the revolving nosepiece to the next higher objective (e.g., from 4X to 10X). Due to the Plan Infinity optical system, the image should remain largely in focus, requiring only minor adjustments with the fine focus knob. When using the 100X objective, apply a small drop of immersion oil directly onto the specimen slide before rotating the 100X objective into position. Ensure the objective lens makes contact with the oil.
5. Using the Trinocular Port:
The trinocular port allows for the attachment of a microscope camera or other imaging device. To direct light to the trinocular port, pull out the light path selector rod (if present) on the side of the head. Refer to your camera's manual for specific attachment and operation instructions.

Manteniment
1. Neteja:
- Components òptics: Use a soft brush or air blower to remove dust from lenses. For smudges, use lens cleaning paper and a small amount of lens cleaning solution. Wipe gently in a circular motion. Never use abrasive materials or harsh solvents.
- Cos: Netegeu el cos del microscopi amb un drap suau iamp drap. Eviteu que la humitat entri en els components elèctrics.
- Oli d'immersió: After using the 100X objective, clean the objective lens and the slide immediately with lens cleaning paper and solution to prevent oil from hardening.
2. Emmagatzematge:
When not in use, cover the microscope with the provided dust cover to protect it from dust and debris. Store it in a cool, dry place.
3. Comprovacions periòdiques:
Periodically check all screws and moving parts for tightness. Do not overtighten.
Resolució de problemes
| Problema | Causa possible | Solució |
|---|---|---|
| Sense il·luminació | Power cord disconnected, power switch off, bulb failure | Check power connection, turn on switch, contact support for bulb replacement. |
| Image is blurry or won't focus | Incorrect focusing, objective not fully engaged, dirty lens, slide upside down | Adjust coarse and fine focus, rotate nosepiece until objective clicks into place, clean lenses, ensure slide cover slip is up. |
| Taques fosques al camp de view | Dust on eyepiece, objective, or condenser | Clean eyepieces, objectives, and condenser. Rotate eyepiece to see if spots move. |
| Imatge massa fosca o massa brillant | Illumination intensity incorrect, iris diaphragm setting incorrect | Adjust brightness control, adjust iris diaphragm for optimal contrast. |
| Difficulty with 100X objective | No immersion oil, air bubbles in oil, incorrect oil type | Ensure a drop of immersion oil is used, remove air bubbles by gently rotating objective, use only specified immersion oil. |
