Course detail
Measurement Technique
FSI-XMT Acad. year: 2019/2020 Summer semester
The course introduces the students to the principles of computer-supported measurement systems. Possible errors in measurements performed by these systems, their corrections and methods of interpretation of the obtained data are explained.
Language of instruction

Learning outcomes of the course unit
After the course, the students are able to design simple measurement systems made of standard components, for example for measurements of length, temperature, location etc., to evaluate the obtained data and to analyze the possible faults of the measurement chain.
Prerequisites
Students are expected to have basic knowledge of metrology, electrotechnics and PC skills.
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.
According to the possibility of teaching can be organized lectures for students by practitioners and excursions to companies focused on activities related to the course content.
Assesment methods and criteria linked to learning outcomes
Course-unit credit is conditioned by 100% attendance at laboratory practicals and approved reports. Examination has a written and an oral part and tests student’s knowledge and his/her ability to apply it in practice.
Aims
The objective of the course is to introduce the students to the computer-supported measurement systems.
Specification of controlled education, way of implementation and compensation for absences
Seminars are compulsory, attendance is monitored. Absence can be compensated on agreement with the teacher.
