The digital electrical multimeter is an electrical test instrument. It measures various electrical parameters required by electrical and electronic professionals and students. The parameters include voltage, current, resistance, continuity and frequency. It measures the parameters from electrical and electronics installations. Additionally, it facilitates the test, repair and diagnosis stages of equipment of electronic and electronic by providing a measurement of their components values. The measured values are presented in a digital format of characters and letters that corresponds to the measured parameter and the corresponding measurement value.
The main components of digital multimeter are the digital display, the electronic circuitry, battery, test leads and the cover. Information on the measured parameters appears on the instrument's display screen. The cover provides housing for the battery and the electronic circuitry. The electronic circuitry manipulates parameters taken at the leads before being displayed on the digital multimeter's display. The battery, on the other hand, provides powers to the digital multimeter’s digital circuitry, the component under test if necessary, and the screen. During measurement, the appropriate function and range covering the parameter under test are established first. Then, the probes are placed on the prescribed part of the test equipment. The measured value and units are displayed on the instrument's display for recording.

The battery of a digital multimeter consists of a set of cells designed to meet its electronics circuit power demand and any necessary power required during tests. The manufacturer states the specification of the battery. A hard non-conductive material that is around the electronic circuit forms the cover. The test leads, on the other hand, are composed of a conductive material such as copper that is insulated leaving a protruding conductive part for electrical parameters measurements and a connection point to the multimeter’s circuit.
