Overview

Precision measurement instruments differ from normal measurement tools because of their ability to measure with a greater degree of precision and accuracy. This course covers how to properly use adjustable parallels, surface plates, optical comparators, and optical center finders.

By the end of this course, you will be able to

• List uses of an adjustable parallel
• Use an adjustable parallel and dial caliper to measure the width of a slot
• Describe a surface plate
• Identify other precision instruments that require a surface plate to measure products
• Explain how an optical comparator works
• Know common methods of measuring with an optical comparator
• Define and explain the optical center finder
• Use an optical center finder to align a drill bushing with scribed hole location lines
