OBJECTIVE

The aim of the course is to produce a competent technician able to interpret data and advise on machine condition. Also it is hoped to improve the interface between the disciplines when deciding on the type of maintenance to be applied. Finally, it is our aim to provide a better all round technician, capable of making these decisions with confidence and accuracy
