1. Measure the length in Cartesian coordinates.
2. Rotate the dial to measure the angle.
3. Used as an observation microscope.
4. Use the movement of the micro-movement stage and the cross coordinate line of the full eyepiece to measure the length.
5. Use the rotary stage and the vernier differential angle plate at the lower end of the eyepiece to match the coordinate line of the address word of the eyepiece to measure the angle, so that one end of the angle to be measured is aligned with the word line, and then let the other - The ends also overlap.
6. Use the standard to detect the pitch, pitch diameter, outer diameter, accuracy and tooth shape of the thread and other dimensions or shapes.
7. Check the grain condition of the metallographic surface.
8. Inspect the condition of the workpiece surface.
9. Detect whether the size or outline of the tiny workpiece conforms to the standard piece.
