Mechanical Measurement and Instrumentation

Course Description

ETM1010C – Mechanical Measurement and Instrumentation is a 3-credit-hour combined lecture and laboratory (C) course classified under the Florida SCNS taxonomy of Engineering Technologies > Mechanics, Fluids, and Heat. The course provides the basic foundation for both mechanical and electronic measurement techniques used in manufacturing and engineering technology environments. Students integrate the concepts, principles, and techniques of mechanical measurement with the use of various types of precision instruments. The course also introduces basic measurement techniques employing electronic test equipment, bridging mechanical and electronic domains of metrology.

This course is commonly offered as part of the Associate in Science (A.S.) degree programs in Engineering Technology, Manufacturing Technology, and related technical disciplines at Florida state colleges.
