Instrumentation and Electrical Measurement

Objectives

Students must acquire the knowledge of the composition, functioning, properties and limitations of the measurement apparatus used in Electrothecnics. Students will become able of executing measurement operations without jeopardizing people and equipments, and without introducing gross errors, and will become able to estimate, limit  or correct measurement errors.   Students must acquire the capacity of writing a complete, concise and precise technical-scientific report.

Teaching method

Scientific principles are explained by the teacher in the theory class, aided by slides. The student’s capacity for oral communication is stimulated through debate around technical and scientific questions.

In practical classes a collection of technical problems is offered to be solved by students based on theoretical class knowledge by calculation. The dialogue between the students is encouraged, and qualitative evaluation is made.

Evaluation method

The precedency (previous taking of) Theoretical Electrotechnics and Electronics 1 is strongly advised! The practical classes with inscription is reserved only for students without the "frequency" already obtained. The ones who possess "frequency" may join (voluntarily) any practical class except the laboratory ones. Any score is only considered positive if its value reached at least 9.5.

1st Way: test No.1 (30%, but with a minimum note of 8, being this test eliminatory, i.e. not permitting continuing this way), test No.2 (45%), 4 reports on laboratory exercises (25 % of the final note, being the reports compulsory for the permission= frequency);

2nd Way: 4 reports on laboratory exercises (25 % of the final note, being the reports compulsory for the permission= frequency), exam of retrying (75%).
