Course Outcomes:

At the end of the course the student will be able to:

Identify the measuring instrument and demonstrate its usage
Calibrate pressure sensor, thermocouple, LVDT and load cell
Explain the usage of slip gauges for calibration of verniercaliper, height gauge and micrometer
Determine the form tolerance (cylindricity and circularity)
Determine thread and gear parameters using standard tests

Conduct of Practical Examination:

1. All laboratory experiments are to be included for practical examination.

2. Breakup of marks and the instructions printed on the cover page of answer script to be strictly adhered by the examiners.

3. Students can pick one experiment from each part from lot prepared by examiners.

4. Max. Marks for part A and B should be 30, 50 marks respectively and for viva 20 marks.

5. Change of experiment is allowed only once and 15% Marks allotted to the procedure part to be made zero.
