6.2.3.1 Vib Calibration Interface

Step 1 Adjust the calibration parameters

The defaults values are:

 Averaging time: 5 s

 Frequency: 157 Hz

 Calibrator Level: 1 g rms

Step 2 Install the calibrator device on the microphone

Step 3 Click START

After the average time is elapsed, the sensitivity value will update.

Step 4 Click OK to accept the sensitivity value

After the average time is elapsed, the sensitivity value will update.

6.2.4 Vib dBref value

The dBref value is the reference value that is used to establish the zero decibel (dB) level. In the

application, the decibel level will be based on this reference. The dBref value for vibration

measurements is normally 1E-6 m/s².

6.2.5 Vib Dynamic Range

The dynamic range of the vibration inputs is around 94 dB. Only one range is available for vibration

inputs. The table below provides examples of the dynamic range limits for given sensitivities of

100 mV/g.
