Digital Multimeter working principle
What is Digital Multimeter? A digital multimeter or DMM is a test instrument used for measuring resistance, voltage, current and other electrical parameters as needed and displays the results of mathematical calculations on LCD or LED readouts. It is a kind of multimeter that works digitally. Digital multimeters are widely accepted worldwide because they have better levels of accuracy and range from a typical 3 ½ to 4 ½ handheld DMM to a very specialized system DMM. Features of Digital Multimeter The digital multimeter is the most advanced measuring instrument that uses modern integrated circuits to create electrical measurements. Some of the features that make it famous in the eyes of professional technicians are: It is light in weight. Giving able to give more accurate readings It measures a lot of physical quantities like voltage, current, resistance, frequency etc. It measures various electrical parameters at high frequencies with the help of special probes. It is less costly. B
