A manual for using a microscope
1. How to use:
1. Place the instrument on the object to be measured, so that the measured part of the object to be measured is illuminated by natural light or light, and then adjust the screw of the eyepiece to make the reticle and the object image clearly visible in the field of view at the same time;
2. When measuring, first rotate the reading drum to move the glass reticle engraved with filaments, and at the same time turn the reading microscope slightly so that the vertical filaments are aligned with the measured part for measurement;
3. See a magnified round hole dent in the field of view. When measuring, first rotate the reading drum to make the vertical filament in the field of view tangent to one side of the round hole dent, get a reading, and then rotate the reading Drum, so that the vertical filament is tangent to the other side of the hole dent, and another reading is obtained;
4. The diameter of the dent in the round hole is the difference between the secondary readings, and it is the thickness of the insulation
2. Matters needing attention:
1. When the instrument can be used normally, never disassemble it by yourself, otherwise it will damage the original accuracy of the instrument;
2. When storing and using the instrument, avoid dust, humidity, overheating and acid-base vapor;
3. Dirt on the surface of the lens must be wiped with a soft object such as absorbent cotton, a soft brush, or lens paper.
