Frequently Asked Questions - OCM 167 Kern
How do I set up the microscope for first use?
Unpack the microscope and place it on a stable, level surface. Plug in the power cord and turn on the illumination. Start with the lowest objective (4x) and adjust the eyepiece distance for your eyes. Use the coarse focus knob to bring the specimen into view, then fine-tune with the fine focus knob.
How do I clean the microscope lenses?
Use a soft, lint-free lens paper moistened with a small amount of lens cleaning solution (or isopropyl alcohol). Gently wipe the lenses in a circular motion. Never use regular tissue or paper towels as they may scratch the lens.
What should I do if the image is blurry?
Ensure the specimen slide is placed correctly on the stage and secured. Adjust the fine focus knob slowly. If using a high-power objective (40x or 100x), make sure the slide is properly positioned and the lens is clean. Also check the condenser and diaphragm settings.
How do I use oil immersion?
First focus the specimen under the 40x objective. Then, with the 100x oil immersion objective, place a small drop of immersion oil directly on the slide cover slip. Rotate the objective into place and use only the fine focus knob. After use, clean the objective lens immediately with lens paper.
How do I replace the LED bulb?
Disconnect the microscope from power. Remove the base cover (usually at the bottom) to access the LED module. Unscrew the defective bulb and replace it with a compatible 3W LED module from Kern. Reattach the cover and plug in.
What maintenance is required regularly?
Clean lenses after each use. Keep the stage and mechanical parts dust-free. Lubricate the adjustment knobs annually with a light machine oil (if needed). Store the microscope in a dry place away from direct sunlight.
Why is the field of view dark?
Check that the illumination is turned on and the brightness is set appropriately. Make sure the condenser iris diaphragm is open. Also verify that the objective is fully clicked into position and that no filter is blocking the light path.
How can I change the interpupillary distance?
Look through the eyepieces and gently hold the two eyepiece tubes. Slide them closer together or further apart until you see a single circular field of view. The distance should be comfortable for your eyes.
What type of slides can I use?
Standard glass slides (25 x 75 mm) and cover slips (18 x 18 mm or 22 x 22 mm) are suitable. For oil immersion, use slides with a cover slip thickness of 0.17 mm. Avoid using plastic slides as they may scratch the stage.
Where can I find spare parts or service?
Contact Kern customer support or visit their official website for authorized distributors. Common spare parts include objectives, eyepieces, bulbs, and fuses. Repairs should be performed by a certified technician to avoid damage.
