An electronic measuring device that combines multiple measurement operations into a single unit is called a digital multimeter (DMM). It has the ability to measure resistance, voltage (both AC and DC), and current (both AC and DC).

• Display: Digital multimeters are easy to read because of their numeric display, which presents measurements as digits. For more dynamic readings, some models additionally come with an analog display or bar graph.
• Voltage: Calculates the difference in electrical potential between two places. It has the ability to monitor voltages of both direct current (DC) and alternating current (AC).
• Current: Calculates how much electric charge is moving through a circuit. It can measure both AC and DC, just like voltage.
• Resistance: The amount that an object opposes an electric current's flow is measured.
