Preview Questions Electronics Maintenance Technician | Role Specific Skill

Question 1: How do you calibrate a signal generator to ensure precise frequency output?

Which action should you take?

Choose only one option

By measuring the output waveform without considering frequency accuracy

By comparing the output to a reference frequency counter and adjusting the generator's output accordingly

By adjusting the frequency and checking the output signal visually

By assuming the generator's settings are correct and measuring the amplitude only

Question 2: Why is calibration of current transformers important in power systems?

Which action should you take?

Choose only one option

To minimize harmonic distortion

To ensure accurate current measurement and relay operation

To increase their efficiency

To optimize load distribution

Question 3: Which parameter does an impedance test measure in an electrical system?

Which action should you take?

Choose only one option

Circuit continuity

System inductance

Opposition to alternating current flow

Load resistance

Question 4: What is the primary tool for diagnosing faults in a high-frequency signal circuit, and how is it used?

Which action should you take?

Choose only one option

A clamp meter, to measure the current without checking the signal

An oscilloscope, to visualize the waveform and identify distortions or irregularities

A digital multimeter, to measure only the voltage levels

A continuity tester, to check for open or short circuits

Question 5: How do you assess and maintain the reliability of a backup power system during preventive maintenance?

Which action should you take?

Choose only one option

By testing the backup system under load conditions only

By assuming the backup system is fully functional and not testing it

By replacing batteries only when they fail

By testing the battery capacity, verifying charging systems, and checking power transfer functionality

Question 6: What is the primary goal of calibrating an industrial weighing scale?

Which action should you take?

Choose only one option

Improve power efficiency

Increase its load capacity

Ensure weight measurements are within specified tolerances using certified weights

Align the mechanical structure
