The PCE-VM 31 is specially designed for measuring and analyzing human body vibrations. The vibration meter can calculate hand-arm vibration measurements according to ISO 5349 and whole-body vibration measurements according to ISO 2631. Besides human body vibration measurements, the vibration meter can also measure machine and building vibrations according to ISO 108160-1/2/3/5/6/7. The meter also supports TEDS, meaning it can automatically detect and recognize TEDS-capable sensors. Overall, the device has 4 independent measurement channels. Vibration acceleration can be displayed with FFT with up to 125 lines. The internal memory can store up to 10,000 measurements or up to 1,000 FFTs, each with date, time, and a comment entry. Measurement data can be transferred to a computer via the USB 2.0 interface.
