Typical multimeter consists of a digital or analog display, a rotary selector switch, input terminals, and test leads (probes). Modern digital multimeters can also measure continuity, diode function, capacitance, frequency, and, in some models, temperature. They provide accurate readings, helping users identify electrical faults, verify circuit operation, and ensure the safe functioning of electrical systems. Proper use and adherence to safety guidelines are important when working with live electrical circuits.
