Instructions for working with KLIPPEL Systems

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.

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 clamping!
  • Don’t breathe in gas and smoke generated by the loudspeaker at high voice coil temperature!
  • Don’t touch hot loudspeakers!
  • Don’t 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! 
  • Don’t touch metal parts of speaker cable clamps!


Original Equipment

  • Don’t modify or repair KLIPPEL hardware or accessories unauthorized!
  • Use original cables, power supply and spare parts only! 


Scanning with Vibrometer System

  • SCN hardware moves the sensors and other mechanical parts automatically. 
  • Please 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!
  • Don’t bruise fingers or other body parts!



  • Fix cables carefully to avoid stumbling!


Working with Vacuum

  • Don’t work with vacuum chamber when the acrylic glass is damaged!
  • Don’t hit the acrylic glass plate when vacuum is applied!
  • Protect your eyes by goggles and wear 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
