Metallographic analysers and their companion microscopes require maintenance
The metallographic analyzer and the accompanying metallographic microscope require maintenance and upkeep during daily use. Its maintenance is the same as that of general optical instruments, it should be placed in a cool, dry, dust-free, acid-base, and steam free place, and covered with a cover when not in use. All lenses of the metallographic image analyzer have been verified and cannot be opened by oneself. If there are stains on the mirror surface, they can be gently wiped with a degreasing cotton dipped in a mixture of alcohol (mixture ratio 7:3), taking care not to let alcohol penetrate into the interior of the objective lens to prevent detachment. Dust on the mirror surface can be blown away with a hair dryer or gently wiped off with a clean brush. Non corrosive lubricants should be applied to clean the mechanical parts. When applying oil, special attention should be paid not to touch optical components, especially the objective lens. The objective and eyepiece of the microscope should be placed in containers containing desiccants after use (self provided). The manufacturer is not bound or informed of any changes to the specifications and equipment of the eyepiece. Cover the tube with a lid to prevent dust. After using the 100X objective lens, the oil should be immediately wiped clean with a fine soft cloth and degreased cotton dipped in a mixture.
Method for replacing the bulb of a metallographic analyzer microscope: Before replacing the bulb, unplug the power plug of the instrument, wait for the bulb to cool down, lay the microscope sideways, and open the lamp chamber cover at the bottom of the microscope stand to replace the bulb. When replacing the light bulb, be careful not to touch it directly with your fingers to prevent grease stains on the surface of the lamp. Do not turn on the microscope power switch before closing the lamp chamber cover. After replacing the bulb, the center of the filament should be checked, and the bulb can be slightly moved up and down, left and right until the filament spot is basically located at the center of the aperture light bar.
