Question 1: A client's automated dispensing system sometimes misplaces adhesive droplets. Which on-site diagnostic step confirms if the dispensing valve timing is incorrect versus nozzle clogging?

Which action should you take?

Choose only one option

Clean the nozzle after every use

Replace the dispensing valves immediately

Adjust dispensing parameters without testing

Use an oscilloscope to monitor the valve actuation signals and correlate with dispensing events, and inspect nozzles for physical blockages under a microscope

Question 2: Which is the best way to handle a language barrier during client communication?

Which action should you take?

Choose only one option

Depend on a translator

Avoid communication altogether

Use diagrams and visual aids

Use simplified technical language

Question 3: Which aspect is critical in ensuring documentation is useful for future troubleshooting?

Which action should you take?

Choose only one option

Completeness and clarity

Length and formatting

Using minimal technical terms

Avoiding detailed explanations

Question 4: How should a short circuit in a PCB be located?

Which action should you take?

Choose only one option

Measure voltage drops with a multimeter

Perform a full system reset

Use a thermal camera

Disconnect all components

Question 5: At a client's production floor, an automated tester intermittently halts with a servo axis overcurrent alarm. Before concluding a drive failure, what on-site action ensures you isolate mechanical binding vs. an electrical drive issue?

Which action should you take?

Choose only one option

Check only the drive's LED status

Manually disengage the axis, rotate it by hand to feel for mechanical stiffness, and measure servo current with a clamp meter while slowly jogging the axis at low speed on-site

Update servo firmware off-site and hope it resolves

Replace the drive immediately

Question 6: How is signal integrity verified during troubleshooting?

Which action should you take?

Choose only one option

Measuring insulation resistance

Observing waveforms on an oscilloscope

Using a logic analyzer

Checking power distribution
