Question 1: How can you identify the root cause of an excessive temperature rise in an industrial furnace?

Which action should you take?

Choose only one option

Assume the furnace is operating efficiently and continue monitoring

Ignore temperature fluctuations and continue operation

Adjust the fuel input without checking other parameters

Check for fuel/air ratio imbalances, malfunctioning thermocouples, or inadequate airflow

Question 2: During testing of a valve actuator, what key parameter should be measured?

Which action should you take?

Choose only one option

The actuator's response time and position feedback accuracy

The external appearance of the actuator

The operating voltage of the actuator only

The internal temperature of the actuator housing

Question 3: When troubleshooting chemical dosing pumps, what is the primary reason for a pump not starting?

Which action should you take?

Choose only one option

Air in the system preventing fluid movement

Blockage in the pump's suction line or clogged filters

Overheated fluid causing the pump to stop automatically

A failure in the electrical control circuit or lack of power supply

Question 4: In troubleshooting a hydraulic pump, what would you check if the system is not reaching the expected pressure?

Which action should you take?

Choose only one option

Let the system operate for a few hours to observe any changes

Assume the hydraulic fluid is contaminated and replace it immediately

Focus solely on the pressure gauge reading without inspecting the system

Inspect for air in the hydraulic lines, low fluid levels, or a malfunctioning pump relief valve

Question 5: What is the significance of zero and span adjustments in calibration?

Which action should you take?

Choose only one option

Zero and span are interchangeable and can be adjusted at any time

Zero and span adjustments are irrelevant in most calibration processes

Zero ensures accurate baseline readings, and span adjusts the instrument to match the full measurement range

Zero is required for only certain types of instruments, while span adjustments can be skipped

Question 6: During maintenance of high-pressure equipment, which safety standard must be followed to prevent catastrophic failure?

Which action should you take?

Choose only one option

Ignoring regular checks for pressure relief valves as long as the equipment is new

Not using protective equipment as long as there is a risk of lower pressure

Skipping de-pressurization if the pressure is below the maximum rating

Ensuring that pressure relief devices are functional and that equipment is de-pressurized before beginning work
