Equipment - MultimetersA multimeter is a type of test and measurement equipment that is used to measure a variety of electrical quantities, such as voltage, current, and resistance. Multimeters are often called "multitesters" or "VOMs" (volt-ohm-milliammeters) because they can measure multiple quantities with a single instrument. Multimeters are commonly used in a wide range of fields, including electrical and electronic engineering, automotive repair, and appliance maintenance. They are available in a range of sizes and styles, from small, handheld units to larger, bench-top models. Multimeters can be used to test and diagnose problems in circuits, to measure the performance of electrical devices, and to ensure the safety of electrical systems.
