Question 1: When performing a continuity test, which safety precaution is essential?

Which action should you take?

Choose only one option

Use the lowest resistance range

Use the highest voltage range

Ignore circuit polarity

Ensure the circuit is powered off and discharged

Question 2: How do you calibrate a sound level meter for environmental monitoring?

Which action should you take?

Choose only one option

Test under ambient noise conditions

Use an acoustic calibrator to verify response at known sound pressure levels

Adjust settings arbitrarily

Measure sound at a single frequency

Question 3: Why is insulation resistance testing critical in preventive maintenance?

Which action should you take?

Choose only one option

To measure system voltage

To monitor power quality

To check relay functionality

To detect insulation breakdown and prevent leakage currents

Question 4: What is the procedure for performing preventive maintenance on a cooling system in an electrical enclosure?

Which action should you take?

Choose only one option

By only checking the fan's operation without cleaning

By inspecting coolant levels, cleaning fans and filters, and checking the system's operational temperature

By replacing the coolant and assuming no further checks are necessary

By assuming the cooling system is fine based on usage history

Question 5: What is the purpose of verifying ventilation systems in electronic equipment during preventive maintenance?

Which action should you take?

Choose only one option

To optimize voltage regulation

To maintain electrical grounding

To prevent overheating of components

To improve circuit continuity

Question 6: How do you inspect and maintain a motor controller during preventive maintenance?

Which action should you take?

Choose only one option

By verifying control signal integrity, checking for heat buildup, and testing the circuit for continuity

By inspecting only the physical housing

By testing only the output voltage and ignoring input and control circuits

By assuming the controller is functioning properly based on motor performance
