and Answers | Latest Version | 2024/2025
| Correct & Verified
What is the purpose of electrical test equipment?
✔✔Electrical test equipment is used to measure, test, and troubleshoot electrical systems to
ensure proper functionality and safety.
Why is it important to use a multimeter in electrical work?
✔✔A multimeter allows electricians to measure voltage, current, and resistance, helping to
diagnose electrical problems and verify circuit conditions.
What is the function of a clamp meter?
✔✔A clamp meter is used to measure the current flowing through a conductor without needing
to disconnect the circuit.
How does a voltage tester work?
✔✔A voltage tester detects the presence of voltage in a circuit, providing a simple way to check
if wires or outlets are energized.

, What should you check before using any electrical test equipment?
✔✔Before using electrical test equipment, ensure it is properly calibrated, the probes are intact,
and it is rated for the specific type of measurement needed.
What is the purpose of a continuity tester?
✔✔A continuity tester checks if a circuit is complete, meaning there is no break or open in the
electrical path.
What is the primary function of an insulation resistance tester?
✔✔An insulation resistance tester is used to measure the resistance of electrical insulation to
prevent leaks or failures that could lead to safety hazards.
Why is it important to properly calibrate electrical test equipment?
✔✔Proper calibration ensures that the test equipment provides accurate readings, which is
essential for safe and reliable electrical work.
What is the difference between a digital and an analog multimeter?
