Electrical Instruments

"Electrical Instruments 251" describes the various roles of electrical testing instruments in maintaining the safety of electrical workers. From the basic galvanometer to today’s digital multimeters, electrical instruments are primarily used to determine if electricity is flowing properly and safely through devices and circuits. Most meters made today are digital. Watt and watt-hour meters are used to measure power or energy. Many other meters, such as oscilloscopes, decibel meters, and "wiggies," are designed for specialized uses. All electrical instruments offer a better understanding of the operating conditions of electricity. Various organizations that set manufacturer standards ensure the accuracy of electrical instruments. Upon taking this course, students will be able to describe how to use electrical measuring instruments to safely and accurately measure electrical variables.
