• Real-time Spectral Analyser in 1/1 & 1/3-octave bands
• Measures all parameters simultaneously with A, C & Z frequency-weightings 
• Measurement of human exposure to whole-body vibration in buildings (ISO 2631-2)

The module for vibration measurements of the SC310 sound level meter adds 2 measurement modes; human exposure to wholebody vibration in buildings mode and FFT (Fast Fourier Transform) narrow band frequency analysis for vibration. The “Human exposure to whole-body vibration in buildings” mode of the SC310 includes a new mode for measuring structural vibration to which human beings are exposed in buildings. This new mode VIBRATION has been designed according to ISO 2631- 2:2003 and along with the preamplifier PA001 and the accelerometer converts the SC310 into a human vibration-measuring instrument according to ISO 8041. (The module for vibration measurements does not include accelerometer). This new mode consists of 3 screens. The first one shows a 1/3 octave band real time spectrum analysis from 1 Hz to 80 Hz, showing the acceleration information in linear [m/s2 ] and logarithmic numerical values [dB referred to 10-6 m/s2 ]. The Second one shows this spectral information in graphic format and also gives the evaluation of the multiplying factor K according to the old ISO 2631-2:1989. The third screen shows linear and logarithmic overall values of acceleration evaluation parameters such as aWm, peak, crest factor, MTVV (Maximum Transient Vibration Value) and VDV (Vibration Dose Value). All these parameters with Wm frequency weighting (ISO 2631-2:2003). The FFT Narrow Band Frequency Analysis for Vibration mode of the SC310 sound level meter carries out a frequency analysis with constant bandwidth filters covering the frequency range from 0 Hz to 1 kHz in real time and in all dynamic measurement range (no scale settings). The FFT analysis has 430 effective lines with a resolution of 2.5 Hz. The vibration module of the SC310 is an optional module and it can be added to new instruments. For old ones, please consult.
