A multimeter is used to measure the basic electrical quantities of current, voltage (AC+DC) and resistance. This versatility is what earned them their name: ‘multi’ (=many) ‘meter’ (=measuring). Most multimeters also enable you to measure additional quantities, such as capacitance, frequency or temperature. At its core, a multimeter is a compact and versatile tool. Digital multimeters are without a doubt the most frequently used measuring tools in the fields of electrical engineering and electronics and are essential for maintenance technicians and engineers.
