What is a Digital multimeter?

A digital multimeter is a device that measures parameters of basic electrical characteristics such as voltage, current, and resistance. The value measured is an analog quantity, but the digital multimeter outputs this as a digital quantity through an analog-to-digital conversion circuit. This distinguishes it from analog multimeters. Also known as a digital tester. There is a compact handy type that can be carried around and a bench top type that is installed stationary.

Application of Digital multimeter

Digital multimeters are used to evaluate various electrical characteristics in the construction and maintenance of electrical equipment. It is often incorporated in power receiving equipment and power control panels. In such cases, in addition to basic parameters such as current, voltage, and resistance, some have built-in functions to measure capacitance, frequency, temperature, and so on. In addition to the above-mentioned specialized uses, inexpensive ones that can be used for electronic work in ordinary households are also on sale.
