What is the principle of measuring a diode with a digital multimeter?
Digital multimeter, a multi-purpose electronic measuring instrument, voltage meter, ammeter, generally includes an ohmmeter function, sometimes referred to as the multimeter, multi meter, multimeter, or three meter. A digital multimeter has a portable device for basic troubleshooting, and a device placed in the workbench, with a resolution of up to seven or eight bits. A digital multimeter is an electronic instrument to be used in electrical measurements. It can have many special features, but the main function is to the voltage, resistance and current measurement, digital multimeter, as a multi-purpose electronic measuring instrument is mainly used for the modernization of the physical, electrical and electronic measurement field.
A diode is a device in an electronic component that has two electrodes, allowing only current to flow in a single direction, and many uses the function of its rectifier. Varactor diodes are used as electronic adjustable capacitors. The current direction of most diodes is usually referred to as rectification. The most common function of diodes is to allow only current to pass in a single direction and reverse over. Therefore, the diode can be thought of as an electronic check valve. An electronic device capable of conducting current in one direction. There is a PN junction and two lead terminals in the semiconductor diode, which have the conductivity of unidirectional current according to the direction of applied voltage.
The principle of measuring diode with digital multimeter is that the analog voltage is changed into digital quantity continuously over time.
