Laser calibration

The laser calibration should be performed by the user from time to time, find instructions in the R&D SYSTEM User Manual “Hardware Guide”.

Microphone calibration

The microphone calibration can be done at 3 different levels of accuracy:

  • All microphones delivered by KLIPPEL come with a sensitivity certificate measured by the manufacturer. This sensitivity value can be imported into the software for calibrating the microphone measurements.
  • To get a more accurate microphone calibration an additional calibrator (offered by KLIPPEL) can be used to calibrate the microphone to the exact working conditions. Temperature, atmospheric pressure and the electrical input behavior are considered during this procedure. This is a very easy and fast calibration and should be done periodically - monthly, weekly or daily depending on the usage of your microphones and the environmental conditions.
  • In addition to the calibration which is normally done at 1 kHz, the frequency response correction curve can be imported into the software. The frequency response curve is delivered by the microphone manufacturer. To verify the frequency response of a microphone it has to be send in to the manufacturer or to any other acoustic test lab that offers such services.
