Course abstract
The aim of the study course is to master the principles and techniques of maintenance and diagnostics of electrical and electronic systems of agricultural and other machines. Skills and ability are acquired in the application of machine-based prophylactic technical maintenance system, in the planning, organization and creation of material and technical base of machine maintenance works.
Learning outcomes and their assessment
Knowledge: about electric and electronic systems service, diagnosis and test methods and equipment for modern machines. Assessment - test.
Skills: choose the most appropriate diagnostic equipment and its use of machine fault detection. Assessment - test.
Competence: acquired knowledge and skills can be available to arrive at a most convenient decision at each situation about strategy and tactics of technical service and diagnostic of machinery. The knowledge and skills acquired during the course are assessed by tests and developed laboratory work and their reports.
