Specific course objectives

The most important formatives objectives of this course are the study of general concepts about measurement and uncertainty, the knowledge of basic instruments, analog and digitals, and the knowledge of measurement methods. This course will deal with the study of modern automatic measurement systems with Virtual Instruments and the acquisition of mechanical and industrial parameters.
