The ability to successfully use motor test instruments will be dependent upon your knowledge of basic electrical theory. The first several hours of this course is “theory review.” It is not only important to understand relationships between voltage, current and resistance, it is also important to understand the characteristics of different circuits and how they affect collected data. In this group of modules, you will review DC and AC theory at a level that will provide you the necessary background to effectively test electric motors both de-energized and energized. This topic in conjunction with the rest of the course will enable anyone that successfully completes this course to become a highly effective motor test technician.
