EMC Training

This four-day course is designed for technicians, operators and engineers who need an understanding of Electromagnetic Interference (EMI)/Electromagnetic Compatibility (EMC) methodology and concepts. The course provides a basic working knowledge of the principles of EMC.

Applying the knowledge and understanding from this course will improve the management of EMC, minimise the risk of unforeseen problems and project/production delays in equipment manufacture thus reducing business risk.
