Content level 2

  • Target group: Production metrologists
  • Learning aims: The Seminar furthers basic knowledge of production metrology for advanced measuring technicians. The didactic approach used in the seminar is based on the latest findings. The content comprises the latest knowledge on the topic, form
  • and positional tolerance, test plan interpretation, programming, monitoring, and the machine and sensor technology used. An enhanced understanding of measuring jobs and influencing parameters enables measuring technicians to reduce measuring uncertainties and thus to make measurement results more reliable and easier to compare. The minimization of costs and waste is supported.
  • Course duration: 5 days
  • Completion: Exam, certificate
