Description

This course covers basic principles of Metrology with instructor demonstration and hands-on use of common precision measuring instruments.

Objectives

Upon completion, Students should be able to:

  • Identify and properly use common measuring tools including steel rules, scales, calipers, micrometers and Vernier calipers
  • Understand differences in measuring tools
  • Become familiar with ID measuring instruments, depth measuring instruments, gage blocks, basic tolerances, and other measuring instruments
