Instructions for working with KLIPPEL Systems

All KLIPPEL Systems must be operated by skilled personnel only. The operator must read and understand the User Manuals. If you have any questions, please contact info(at)klippel(dot)de 


Working with Laser

  • Avoid direct or indirect (reflection) exposure of human eyes to the laser beam!


Testing Loudspeaker

  • Testing loudspeakers can be dangerous when going to the physical limits!
  • Protect your ears when testing at high sound pressure level!
  • Only test loudspeakers in a fire proof environment and use clamping!
  • Do not breathe in gas and smoke generated by the loudspeaker at high voice coil temperature!
  • Do not touch hot loudspeakers!
  • Do not drop heavy loudspeakers, move them carefully! 
  • Check any measurement setups before executing the test. The user must assure a safe sound pressure level!


Electrical Devices

  • Only use intact grounding type plugs for the power supply of all KLIPPEL electrical devices and connected 3rd party equipment!


Power Amplifiers

  • Power amplifiers may generate high voltages at the loudspeaker terminals which can be dangerous! 
  • Do not touch metal parts of speaker cable clamps!


Original Equipment

  • Do not modify or repair KLIPPEL hardware or accessories unauthorized!
  • Use original cables, power supply and spare parts only! 


Near Field Scanner System

  • The area of movement must be clearly marked and is restricted to authorized personnel only.
  • No personnel is allowed in the restricted area while the machine is moving.
  • Make sure the power switch box / Emergency-Stop is within reach of the operator at all times during operation.
  • Regular safety checks must be carried out every 100 hours of operation.
  • Be careful when placing heavy DUT onto the platform and when removing it. Make sure it is positioned in the centre of the platform.
  • The operator must read the User Manual carefully and strictly follow all safety instructions.


Scanning with Vibrometer System

  • SCN hardware moves the sensors and other mechanical parts automatically. 
  • Keep fingers or other body parts away from moving parts!
  • Press red STOP button (at Scanner Hardware or at Motor Control device) to avoid injury!


Driver Stand

  • Use one-hand operation carefully!
  • Do not bruise fingers or other body parts!



  • Fix cables carefully to avoid stumbling!


Working with Vacuum

  • Do not work with the vacuum chamber when the acrylic glass is damaged!
  • Do not hit the acrylic glass plate when vacuum is applied!
  • Protect your eyes by wearing goggles and gloves when working with vacuum!
  • Keep all objects and body parts in a safe distance from the air intake when releasing the vacuum!


Suspension Part Testing

  • Put the fastening tool on the guiding rod when running SPM tests to avoid expelling clamping parts!


Interfacing software to 3rd party products (IO-Monitor -QC Software, Automation Software)
Apply protection algorithms to avoid any malfunction of 3rd party software due to 

  • malfunction in interfaces
  • unexpected freeze of Klippel software
  • unknown state during initialization and exit of Klippel software interfaces


Interfacing hardware to 3rd party products (GPIO Connector at PA hardware)

Apply protection algorithms / circuits to avoid any malfunction of peripheral equipment due to 

  • malfunction in interfaces
  • unknown behavior in inactive state (device switched off and during switching process)
  • impact of electro-magnetic interference
  • instable power supply 


Please note, the results of measurements (measuring data, parameter, curves, PASS/FAIL decisions) depend on the measurement methods and the setup made by the user. The measurement methods are described in the KLIPPEL‘s specifications, papers and user manuals. KLIPPEL is not liable for any damage caused by interpretation or misinterpretation of measurement results.
