When should electrical test equipment be inspected?

• A. After every use
• B. Only when damaged
• C. Never
• D. Before every use

Answer: (D)

Before every use is the best practice for electrical test equipment. This approach catches issues that can be present from storage or developed during handling, such as damaged insulation, frayed cords, cracked probes, or loose connectors, which might not be obvious until the tool is used. A quick pre-use check verifies that the leads, probes, plugs, connectors, and switches are intact and that the instrument is safe to energize and capable of giving accurate readings. If any defect is found, do not use the instrument and arrange for repair or replacement. Relying on post-use inspection or only checking when damaged can miss hazards and lead to unsafe conditions or bad measurements, and never inspecting is unsafe.
