A week-long course aimed at beginners in vibration diagnostics who have a short experience in vibration measurements.

The course is a basic initial step for specialists wishing to continue their work in vibration diagnostics, includes a large amount of theoretical material and introduces the listener to the basics of vibration measurement and analysis.

At the end of the course, the specialist takes a certification exam for the qualification "I level specialist in vibration diagnostics"
