Anatomy of a Digital Caliper Micrometer
1. Measuring Jaws
The measuring jaws are the primary components used to measure the distance between two surfaces. One jaw is fixed, while the other moves along a graduated scale.
2. Spindle
The spindle is a screw mechanism that moves the movable jaw. It has a fine pitch, allowing for precise adjustments.
3. Vernier Scale
The vernier scale is a secondary scale etched on the movable jaw. It allows for precise readings down to fractions of a millimeter.
4. Digital Display
The digital display provides a clear and easy-to-read measurement. It eliminates the need for manual calculations and reduces the risk of errors.
5. Buttons
Most digital caliper micrometers have buttons for zeroing the display, changing measuring units, and switching between absolute and incremental modes.
