Dimensional Measurement Tools – Basics

January 27 - January 28


Course Objectives

This program provides a fundamental and practical review of Basic Dimensional Measurement Tools and Methods, including variable gages such as steel rules, depth and dial gages, micrometers, and calipers. In addition, attribute gages such as plug, ring and screw thread gages are covered.


Basic Dimensional Measurement Tools and Methods builds a solid foundation of skills that workers can use across a broad spectrum of applications. It forms the basis for mastering more advanced measuring tasks to ensure that you’ll get the most accurate measurements possible. With this program, workers will master the essentials of handling, applying and reading the most common gages on today’s shop floors from steel rules to micrometers and height gages.
What good is a measurement result if it has been measured incorrectly? There are many sources of measurement errors that can be easily avoided if we know how to recognize them. We focus on common measurement errors and how to avoid them!
