Lectures:

Study texts for the lectures are available on the Internet.

Laboratory exercises:

Textbooks and manuals for laboratory work are available on the Internet.

Before beginning work, students are tested in writing from knowledge of the issue.

Individual project:

Students will prepare individual project with the theme of technological measurements. The project assignment is based on the specialization the student. Presentation and defense of the project will take place during the exam test.

Requirements to the exam -
Last update: Pátková Vlasta (20.04.2018)

Before beginning any laboratory work, students are tested in writing.

The protocol for the laboratory work writing and casting process in electronic form within a week after completion of the work.

Successful completion of all laboratory work is a prerequisite for obtaining credit.

The exam is oral or written. A separate part of the test is to present and defend the project of technological measurements according to individual specifications. The questions in the exam include issues by syllabus and for study are sufficient background materials for lectures.
