Using Multimeters (Level 4). Sometimes training needs to start with the basics. That is what our Fundamental Electrical Maintenance classes (FEMS) were specifically designed to do. Schaedler Yesco is proud to have developed this stepped series designed for industrial maintenance personnel looking to add or improve a skill set and improve plant reliability. These courses are also appropriate for electrical contractors looking to enter industrial automation. The FEMS curriculum provides basic electrical theory and hands-on experience. Each class is taught by a professional instructor with practical electrical experience. Textbooks are provided for all FEM classes. Sign up for three or more classes and you keep the book!
