Electrical Instruments 251
This class describes the purpose of common electrical testing instruments. Electrical instruments are primarily used to determine if electricity is flowing properly and safely through devices and circuits. Commonly used devices include ammeters, ohmmeters, voltmeters, digital multimeters, and others used for specialized purposes. Most meters are digital, but analog instruments are also available. All electrical instruments are used to better understand the operating conditions of electrical equipment, find faults, and ensure equipment is safely de-energized before starting maintenance.
Knowledge of electrical instruments is important for anyone maintaining electrical equipment. Upon taking this course, students will be able to identify common measuring instruments and describe how to use them to measure electrical variables.
