Syllabus Discussion, Laboratory equipment procedures and practice, electronic component value reading

2-3 Perform different methods of making DC voltage and current measurement; identify when each method is applicable; specify the degree of accuracy of any measurement made and identify the main causes of error.

DC Measurements

4 Perform different methods of measuring resistance; identify when each method is applicable; Specify the degree of accuracy of any measurement made and identify the main causes of error.

Resistance Measurements

5 Assess basic laboratory, instrumentation and measurement skills; review and apply learned concepts and skills from the 1st two experiments.

1st Practical Exam (For topics covered in meetings 1 to 4)

6-7 Describe the operation of a triggered sweep oscilloscope; make basic measurements using an oscilloscope; specify the degree of accuracy of any measurement made and identify the main causes of error.

X. Class Policies

a. Students must form a group (maximum of 3) for each experiment and for the project. b. Each group must submit a laboratory report (called Post-Lab) answering the guide

questions in the experiment, at the least. Further observation and in-depth analysis will earn additional merit. The laboratory report must be submitted in-print (not necessarily coloured) two weeks after the experiment (due 30 minutes from official start). Late papers will NOT be accepted.

c. All laboratory reports must be in IEEE paper format. Template will be given by the instructor.

d. For any submitted report, never forget to cite your reference/s if theres any. Failure to properly document and acknowledge an existing work is considered intellectual malpractice.

e. Student/s arriving 30 minutes late will be considered absent and will receive no grade for the pre-lab and the corresponding laboratory report for the experiment on that day. However, for the love of learning, he/she/they can still join his/her/their group-mates in performing the experiment. No make-up class for unexcused absence/s.

f. Student/s incurring more than three (3) absences will be advised to drop the course or will be given a failing grade if the dropping period has lapsed.

g. Work ethics inside the laboratory must be observed. Phones or gadgets can be used shortly for documentation purposes. Clean up your workplace when done. Make sure to turn off all equipment and measuring tools / devices before leaving. Components used must be returned properly.
