What is a digital multimeter?

A multimeter is an instrument that can measure a wide range of parameters, such as alternating (AC) or direct current (DC) voltage, AC or DC current, resistance, temperature, capacitance, and so on. Modern digital multimeters use digital and logic technology to become smaller and smaller with more and more built-in functions. By introducing digital technology, thedigital multimeterThe meter can provide graphical display, data logging and signal digitization, and programming functions, as well as communication with external devices.
