Definition

1. Noun:
   • A precision measuring instrument: A "micrometer caliper" is a tool used for making extremely precise linear measurements, typically of small distances, thicknesses, or diameters. It functions as a caliper but incorporates a calibrated screw mechanism for high accuracy.

Usage Examples

• Noun:
  • The machinist used a micrometer caliper to measure the thickness of the metal sheet to within a thousandth of an inch.
  • For accurate results in the experiment, the diameter of the wire must be checked with a micrometer caliper.

Advanced Usage

• "To take a micrometer caliper reading": The act of using the instrument to obtain a measurement.
  • After taking a micrometer caliper reading, he recorded the value in his lab notebook.

Variants and Related Words

• Micrometer (n): Often used as a shortened, more common term for a micrometer caliper. It refers to the same type of precision measuring tool.
  • He adjusted the micrometer to zero before taking the measurement.
• Micrometer gauge (n): Another term for the same instrument, emphasizing its function as a gauge.
• Caliper (n): A broader category of measuring instruments with two adjustable legs or jaws. A micrometer caliper is a specific, highly precise type of caliper.

Synonyms

• Micrometer: The most direct synonym.
• Micrometer gauge: A functionally equivalent term.

Related Phrases

• Outside micrometer (caliper): A type designed to measure external dimensions like thickness or diameter.
  • Use the outside micrometer caliper for the shaft's diameter.
• Inside micrometer (caliper): A type designed to measure internal dimensions, like the diameter of a hole.
• Digital micrometer caliper: A modern version that provides a digital readout instead of a mechanical scale.
