METR 111 - Physical Metrology

3 Credits: (2 lecture, 3 lab)

Course Description
This course is a study of physical metrology emphasizing the theory and proper use of applied mechanical measurement equipment. The intent is to develop the student’s interest and understanding of physical metrology along with a thorough knowledge of laboratory technique. 

Note Field trips may be required.  Spring semester only.

Prerequisite METR 110.Corequisite PHYS 102.

A. Differentiate physical metrology from other metrology fields.

B. Recognize common instruments of physical metrology.

C. Demonstrate proper measurement methods for common physical metrology instruments.

D. Determine the proper instrument for various measurement situations.

E. Organize instruments into practical measurement systems.

F. Assess measurement systems for potential errors.

G. Analyze test results in order to draw conclusions.
