Levels
- Major Types:
- Tilting levels: The coincidence level must be adjusted before each reading, the telescope can be tilted by one screw. Very accurate.
- Automatic Levels: Uses an automatic compensator to level the line of sight. The compensator is a group of prisms suspended by wires as pendulum. Accuracy varies. Can include a parallel plate micrometer to measure to 1/100 mm.
