Operation
1. Insert the eyepiece into the eyepiece tube, and screw the objective into the nosepiece. During observation, put the specimen in the center of the stage and held with the slide holder. First, use the 10X or 4X objective to find the object, then turn to the high-magnification objective for observation, turning the fine-focusing knob until the image is clear. When using 100X oil objective, should fill a drop of cedar oil between the specimen and lens, without bubbles. After used, the lens should be cleaned with xylene immediately to avoid the solidification of the cedar oil.
2, In order to get a bright and clear image when observing, must pay attention to the adjustment of the illumination system. When using the different magnification of the objective lens, should adjust the condenser and change the aperture of the light bar, so that the aperture can adapt to the objective. Generally speaking, when the magnification of the objective lens increases, the condenser should be moved upward. The aperture light bar is designed for adjusting aperture, not the brightness.
Maintenance
1 When the microscope is finished observing or suspended, cut off the power supply to avoid the electrical components in the instrument are still in the working state. When not used for a long time, the power plug should be removed from the power socket and all transmission wires should be properly kept.
2 Clean lens: Use a blow ball or a soft brush to wipe the dust off the lens. Heavy dirt and fingerprints can be gently wiped by lens paper or soft cloth dipped in a little alcohol and ether mixture (the mixture of the two is about 20 to 30% alcohol, 70 to 80% ether).
3 Clean instrument surface: Can be wiped with a clean soft cloth; Heavy dirt can be scrubbed with a neutral cleaner.
4 Storage: if you do not use the microscope for a long time, please turn off the power supply of the instrument, fully cool the bulb, put the dust-proof cover on the microscope, and put it in the packing box. Store in a dry, ventilated, clean and acid-alkali vapor-free place to avoid mold.
