Reading Electrical SchematicsThese basic tutorials start with electrical symbols and schematic design andproceed to include the specific schematics for the production machines you usein your plant. They are designed to help you use an electrical schematic to workyour way through any problem that may occur during the manufacturing process.Being able to read and understand an electrical schematic is the fastestway to solve an electrical problem. We suggest that you start with the tutorialnamed What is an Electrical Schematic, to help you understand what some ofthe electrical symbols represent and how the electrical schematics work. Thetutorials will run automatically in Windows Media Player.You can pause, go forward, or go backward during the presentation. Whenfinished, just close Media Player. Each module takes about ½ hour to complete.
