🔍 Key Concepts

• Basic electrical safety practices when working on live circuits • Purpose of initial checks before detailed troubleshooting • Difference between measuring voltage, current, and using different meter ranges

💭 Think About

• Before you start detailed testing, what do you need to confirm about the circuit’s overall condition? • Which action is safest and most logical to do before you disconnect components or run current measurements? • Which option represents a general preliminary check, rather than a more advanced or intrusive test?

✅ Before You Answer

• Identify which choice reflects a simple, global check of the system rather than a detailed measurement. • Consider which action reduces the risk of damaging the meter or the circuit on the very first test. • Ask: which step would an experienced technician do right after turning on the equipment, before anything else?
