3. Using tools based on their functions and operation

4. Whenever you perform a task in the workshop you must use personal protective clothing and equipment (PPE) that are appropriate for the tasks, and which conforms with your local safety regulations and policies. Your skill in using tools and equipment will make your work less difficult and ensure that tasks are performed properly and safely.

5.  Hand tools o screwdrivers, needle-nose pliers  D iagnostic tools o analog or digital volt-ohm-milliammeter, power supply

6. Safety check:  D o not use flammable cleaners or water on electrical equipment.  Make sure designated walkways are kept clear of any obstructions.

7.  Always wear protective clothing and use the appropriate safety equipment.  Make sure that you understand and observe all legislative and personal safety procedures when carrying out the following tasks.

8. Proper use of hand tools:  use the proper type and size of screwdriver by matching it to the screw.  Phillips and flat head are the most common types.  Do not over tighten screws because the threads may become stripped.

9. Open-Ended (Critical Thinking & Troubleshooting) Question: John is using a VOM to check a wall outlet voltage. He sets the dial to DC voltage instead of AC voltage . What mistake did he make? What will likely happen to the reading? How should he correctly measure the voltage?

10. Sample Answer: Mistake: John set the VOM to DC voltage , but a wall outlet provides AC voltage . Reading Effect: The VOM may show 0V or an incorrect reading . Correct Method: John should switch the VOM to the AC voltage (V~) setting and select a range higher than the expected voltage (e.g., 200V for a 120V outlet).
