Question 1: When using an oscilloscope for power-on functional testing, which feature helps in distinguishing between transient spikes and steady-state noise?

Which action should you take?

Choose only one option

Auto-triggering mode.

Peak detect triggering and appropriate vertical scaling.

Single-shot acquisition without triggering.

Continuous wave measurement mode.

Question 2: How do you measure the impedance of a component using an LCR meter?

Which action should you take?

Choose only one option

Use the meter in resistance mode and calculate impedance

Set the meter to measure inductance and calculate impedance

Set the meter to capacitance mode and calculate impedance

Set the meter to measure impedance, apply a known frequency, and observe the results

Question 3: Which component defect is identified by a short circuit across its terminals?

Which action should you take?

Choose only one option

Faulty diode

Shorted capacitor

Defective inductor

Open resistor

Question 4: How should you report test results for a component that did not meet the expected tolerance limits?

Which action should you take?

Choose only one option

Simply mark the result as a failure without further details

Provide the average measurement and ignore individual deviations

List only the deviation without explaining the cause

Clearly specify the measured value, tolerance, and potential reasons for deviation

Question 5: What is the significance of an ESR test in capacitor diagnostics?

Which action should you take?

Choose only one option

To check insulation resistance

Question 6: What is the impact of using a soldering iron with too much wattage for small components?

Which action should you take?

Choose only one option

It will improve the precision of the soldering joint

It can lead to excessive heat, damaging the component or the PCB

It will reduce the soldering time

It will not affect the soldering process if used briefly
