MT 241 System Calibration and Standards

Lecture Hours: 1
Lab Hours: 2
Credits: 2

Presents the why’s and how’s for organizing, modifying, and improving the operation of industrial calibration and repair. Covers examination of the standards and criteria for evaluating a process control system or proposed laboratory. Offers a combination of practical information and hands-on experience, covering proper installation, calibration, and maintenance of electronic instruments. Builds on the characteristics of electronic control systems, including techniques for installing electronic instruments; and procedures for configuring and calibrating transmitters, transducers, and controllers in process control systems.

Prerequisite: ELT 100 or ELT 131; and MT 215; or consent of instructor. (All prerequisite courses must be completed with a grade of C or better.)
