4. Planning of Engineering Measurements (Laboratory Projects)
Ideal engineering measurement (laboratory project) should be entirely planned by the student and may include:
objective
method
organisation of personnel
analysis of results

5. Objectives of Engineering Measurements
General objectives of this course are to prepare students to undertake later original projects in research and design and to provide some background for assignments he/she may expect as a junior engineer in industry.

6. Principles of Engineering Measurements (Basic Concepts)
Definition of terms
Calibration
Standards
Dimensions and units
Generalised measurement system
Basic concepts in dynamic measurements
System response

7. i- Definition of Terms (Week2)
Readability: This term indicates the closeness with which the scale of the instrument may be read:
an instrument with a 10 scale would have a higher readability than an instrument with a 5 scale. For an instrument with a digital readout this term have a little meaning. In this case display of the instrument is important.
Sensitivity: Ratio of the linear movement of the pointer on an analog instrument to the change in the measured variable causing this motion. For example, a 1-mV recorder might have a 25-cm scale length. Its sensitivity would be 25 cm/mV, assuming that the measurements was linear.
Hysterisis: if an instrument displays a difference in readings one talks about hysterisis, which may be the result of mechanical friction, magnetic effects, elastic deformation or thermal effects.

8. i- Definition of Terms
Accuracy: of an instrument indicates the deviation of the reading from a known input. Accuracy is frequently expressed as a percentage of full-scale reading, so that a 100 kPa pressure transducer having an accuracy of 1 percent would be accurate +-1 kPa over the entire range of the transducer.
Precission: This term indicates the ability of an instrument to reproduce a certain reading with a given accuracy. 8
