The KLIPPEL QC System combines the advantages of a comprehensive software and hardware solution with the flexibility of a modular system. QC Basic fulfills common demands of modern end-of-line testing while keeping an eye on the budget. QC Standard is based on the same measurement hardware and software framework, enhanced by advanced features setting new standards in speaker and audio system testing.


Unique extension modules integrate seamlessly for advanced applications like nonlinear parameter testing or leak detection. Additional software tools are available for data post processing, statistics, process control and much more. for special requirements, QC Standard provides a plug-in customization infrastructure to integrate tailor made features easily. This all is supplemented by a selection of hardware accessories for an all-in-one comprehensive testing solution.

 

The QC Start tool is a simple, yet efficient software framework exclusively designed for daily QC business:

  • Simplify test and data management
  • Simple test selection by barcode
  • Define operator rights and instructions
  • Synchronize multiple production lines
  • Access remote online support
