measurement with a microphone, the standard dB reference value is 2E-5.
Sensitivity This is the sensitivity of the input measured in mV/Unit. The sensitivity is used by the
interface to present a calibrated signal in the acquisition tab and post-processing
module. The sensitivity can be manually entered if the value is known, or automatically
determined through the use of the calibration function via the Cali(x) button (see next
paragraph for more information on this function).
Calibration Function
This function is used to determine the input sensitivity. The calibration task is supported by
a dedicated interface. Note that a microphone or accelerometer calibrator is required. The
interface of the calibration function is presented in Figure 7.

Before starting the calibration measurement, the following calibrator parameters must be
set up:
Calibration level: The calibrator level can be defined in dB rms 2 or as a linear rms value.
Use the menu on the right to specify if the calibrator level is in dB or a linear value.
