This course picks up where First Line Diagnostics finished and uses what we have already learned to ‘map out’ a control system and use this ‘map’ to improve fault finding techniques . The course consists of a series of practical exercises aimed at engineers, technicians and others who are the first to respond to breakdown situations. On completion of this course candidates will be able to implement the knowledge gained into their own work environment with an aim to making fault finding more efficient, thus reducing financial losses incurred by unexpected down time.
