Course Summary

QC Training Services’ Dimensional Measurement Tools – Basics class is an introduction to some of the most common gages used on the shop floor. The purpose is to provide practical instruction on the different tools available and their proper use to build workers’ skill and knowledge.


“Had a great pace. He never went so fast as to make me feel lost. Very patient. Each tool was explained and he took time to make sure you knew how to use each device.” – Kelley, Minnesota

“I liked that we not only learned the material, but had hands on training and exercises to help fully understand how to use and implement the tools.” – Arvette

“All that was done was perfect. Instructor helped in answering all my questions even when I was unsure of what I was asking.” – Keith, Minnesota

Target Audience

Anyone involved in any aspect of inspection and providing measurement data should attend – production workers, machine operators, quality control, shipping and receiving, or individuals looking for an overview.

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!
