Explores the basic functions of the VOM multimeter, including measuring voltage, current, and resistance. Identifies aspects of meter safety, care of the multimeter, and protecting equipment. Discusses the characteristics of the digital multimeter, as well as the clamp-on meter. Covers reactive circuit elements—capacitors and inductors—and then addresses practical applications of both current and resistance measurements. Includes a meters lab book supplement, with experiments to be performed on the mini Electra Lab.
