Fluke 117 Handheld Digital Multimeter

The bench-grade multimeter that shop mechanics reach for first. True-RMS readings handle the noisy alternators and DC-DC converters on modern bikes without giving false readings. Non-contact voltage detection (VoltAlert) lets you probe live wires without making contact — invaluable for tracing 12V accessory circuits without yanking panels off. CAT III 600V rating means it survives the occasional contact with a wall-outlet circuit while you're working on the bike. Auto-ranging, large backlit display, and 6000-count resolution. This is a tool you keep for twenty years.
