3. Package Contents

Verify that all components listed below are present in your package:

• Trinocular Microscope Unit
• 1 Pair of DIN WF 10x Eyepieces (23mm diameter)
• 4-fold Objective Revolver (pre-installed)
• 4 DIN Objectives: 4x/0.1, 10x/0.25, 40x/0.65, 100x/1.25 (Oil Immersion)
• Condenser
• Mechanical Stage with Vernier Scale
• Fine and Coarse Focus Drive (integrated)
• Immersion Oil
• Power Cord
• Dust Cover (if included)

4. Setup

1. Unpacking: Carefully remove all components from the packaging. Retain the original packaging for future transport or storage.
2. Placement: Place the microscope on a stable, vibration-free surface away from direct sunlight and heat sources. Ensure adequate space around the microscope for operation.
3. Eyepiece Installation: Insert the 10x WF eyepieces into the eyepiece tubes of the trinocular head. Gently push them down until they are seated firmly.
4. Objective Installation: The objectives are typically pre-installed on the revolving nosepiece. If not, carefully screw each objective into the nosepiece in ascending order of magnification (4x, 10x, 40x, 100x).
5. Power Connection: Connect the power cord to the microscope's power input and then to a suitable electrical outlet (6 Volts).

5. Operating Instructions

5.1 Preparing a Specimen

• Place a prepared slide onto the mechanical stage.
• Use the stage clips to secure the slide.
• Use the X-Y stage control knobs to center the specimen area you wish to observe under the objective.

5.2 Illumination

• Turn on the LED illumination using the power switch.
• Adjust the brightness using the dimmer control.
• Adjust the condenser and iris diaphragm for optimal contrast and resolution.

5.3 Focusing

1. Rotate the revolving nosepiece to select the lowest magnification objective (4x).
2. Using the coarse focus knob, lower the stage until the objective is just above the slide.
3. While looking through the eyepieces, slowly raise the stage using the coarse focus knob until the specimen comes into view.
4. Use the fine focus knob for precise focusing.
5. Adjust the interpupillary distance by moving the eyepiece tubes until you see a single, circular field of view.
6. Adjust the diopter setting on one eyepiece (usually the left one) to compensate for differences in vision between your eyes.

5.4 Changing Magnification

• Once focused at a lower magnification, rotate the nosepiece to the next higher objective (e.g., 10x).
• Only minor adjustments with the fine focus knob should be needed due to the parfocal design of the objectives.
• For the 100x oil immersion objective, place a small drop of immersion oil directly onto the slide in the area to be observed. Carefully lower the 100x objective into the oil drop until it makes contact. Focus using only the fine focus knob.

6. Maintenance

• Cleaning Optics: Use a soft, lint-free cloth and specialized optical cleaning solution to clean objective lenses and eyepieces. Never use abrasive materials or household cleaners. For oil immersion objectives, clean off immersion oil immediately after use.
• Cleaning Body: Wipe the microscope body with a soft, damp cloth. Avoid getting moisture into electrical components.
• Storage: When not in use, cover the microscope with the provided dust cover to protect it from dust and debris. Store in a cool, dry place.
• Lubrication: Moving parts like the focus mechanism and mechanical stage are factory-lubricated and generally do not require user lubrication. If movement becomes stiff, contact professional service.
