The PCE-VM 31-HAWB Human Vibration Analyzer is designed for measuring human vibration at the workplace. The Vibration Analyzer can calculate hand-arm vibration measurements according to ISO 5349 and whole-body vibration measurements according to ISO 2631. Each sensor consists of a triaxial Vibration Analyzer that captures acceleration, velocity, and displacement measurements. In addition to human vibration measurements, the Vibration Analyzer can measure the vibrations of machines. The Vibration Analyzer also supports TEDS, which means that it can detect and identify TEDS-capable sensors automatically. Overall, the device comes with 4 independent measuring channels. The measured data can be displayed as interval, running or maximum RMS (MTVV), as well as estimated vibration dose value (eVDV), vector sum, peak, and maximum peak. The acceleration can also be displayed as FTT with up to 125 lines. The internal flash memory of the Vibration Analyzer can store up to 10,000 measurements or up to 1,000 FTTs, each with date, time, and a comment. The measured data can also be transferred to a PC via the USB 2.0 interface.
