fuse multimeter

Many handheld multimeters include internal fuses—often two fuses—described as built-in, dual, or double-fuse protection. These fuses are placed to protect current ranges and help prevent damage from overloads.

NCV lets the meter detect live AC voltage without touching the conductor. Meters with NCV typically give audible beeps and flashing lights to indicate AC presence, with louder/faster or brighter alerts as the detected field strength increases.

Multimeters combine internal fuses with overload protection circuitry to interrupt dangerous currents. Many models also use shock- or rubber-resistant housings and reinforced enclosures to reduce impact and electrical-shock risk, helping protect both the user and the instrument.

Beyond voltage and current, many multimeters include resistance, capacitance, frequency, diode and continuity tests. Some also list temperature measurement, transistor gain (hFE), and dedicated battery-test modes.

Common kit accessories include test leads (and often alligator clip adapters), batteries, a carrying case, and a user manual. Some kits also include a thermocouple or additional probe tips.
