Preview Questions Maintenance Technician | Role Specific Skill

Question 1: When calibrating a vibration sensor on rotating equipment, what is the primary factor to monitor during the calibration process?

Which action should you take?

Choose only one option

Calibrate the sensor to a known fixed value without considering operating conditions

Check only the wiring and power supply to the vibration sensor

Ensure the sensor's frequency response is in alignment with the expected operational vibrations

Verify the sensor's material properties and robustness

Question 2: How should a technician approach troubleshooting a heat exchanger that is not performing efficiently?

Which action should you take?

Choose only one option

Ignore the issue and continue using the heat exchanger at reduced efficiency

Replace the entire heat exchanger without examining its condition

Check for fouling, corrosion, or flow issues in both the hot and cold sides of the exchanger

Focus only on the external temperature measurements

Question 3: How should a Maintenance Technician assess the condition of a motor during routine preventive maintenance?

Which action should you take?

Choose only one option

By examining the motor for external visual damage without testing internal components

By checking the motor's electrical connections, inspecting the windings, and testing the insulation resistance

By replacing the motor's bearings and lubricating it annually

Only by measuring the motor's speed and temperature

Question 4: When installing a new electrical panel in a hazardous area, what is the key consideration for safe operation?

Which action should you take?

Choose only one option

Focusing only on the panel's cosmetic appearance and ignoring safety checks

Ensuring compliance with explosion-proof standards, proper grounding, and secure wiring

Installing the panel without checking the surrounding environmental conditions

Only verifying that the panel doors are closed tightly

Question 5: When diagnosing an issue with a high-pressure safety relief valve in a chemical process, what is the most important factor to check first?

Which action should you take?

Choose only one option

The system's pressure settings and calibration

The condition of the valve actuator and control signals

The vibration levels of the valve during operation

Whether the valve is seating properly and has the correct spring tension

Question 6: In a centrifugal pump, if the discharge pressure is low but the pump is operating at the correct speed, what is the most likely cause of the issue?

Which action should you take?

Choose only one option

Excessive bearing wear causing friction

Misalignment of the pump shaft

A clogged impeller or suction line restriction

Low voltage supply to the pump motor
