VC431 Triaxial Vibrometer The VC431 is a high performance vibrometer; the ideal instrument for measuring vibration according to: • Directive 2002/44/EC on risks deriving from workers’ exposure to vibration. ° Vibrations transmitted to the hand-arm system (HA) ° Vibrations transmitted to the whole body (WB) The VC431 enables the user simply and comfortably to follow the technical guides for the evaluation and prevention risks related to mechanical vibration of most countries. • Directive 2002/49/CE: • Vibration in buildings Applications • Assessment of workers’ exposure to vibration: • Hand Arm (HA) 2002/44/EC ISO 5349-2 • Whole Body (WB) 2002/44/EC ISO 2631-1 • Assessment of vibration in buildings: • ISO 2631-2 (Buildings) User-Friendly • Measures all parameters simultaneously for each application (HA, WB, Buildings) • Single measurement scale, independent of the application (HA, WB, Buildings) • Projected information displayed during the measurement. • Large 3,2” high resolution, backlit graphic display. • Just three operating keys (Soft key). Characteristics • Large storage capacity; saves the time history of the measurement. • Downloading and powering via USB port. • Projection of parameters; evaluation of exposure to vibration for measurement times below the exposure time. • Software: CESVA Capture Studio and CESVA Studio Editor. • Accelerometer different for each application (HA, WB, Buildings). • Vibrometer complies with norm ISO 8041.
