The Rion VM-54 and VX-54WB1 Whole Body Vibration program are ideal for measuring vibration levels in accordance with BS 6472. The system directly measures and logs Vibration Dose Values with all the current applicable weightings (user selectable). The VM-54 long-term kit includes a weather-resistant case and gel cell batteries. The 6 volt version will run for 4 days and the 12 volt version will run for 7 days. It's as simple as leaving a sound level meter out for a long-term survey. You just set the meter up to log at, say, 1 or 5 minute intervals and return a few days later to pick up the data. The meter stores the VDVs (and other indices) to a compact flash card in a sensibly formatted comma separated variable text file which pulls straight into a spreadsheet program for easy manipulation.

• 3 channel compact, lightweight and practical vibration meter for site use
• Directly measures and logs VDV's
• Can be used with tri-axial or individual accelerometers
• Sensitivity can be adjusted separately for each channel allowing most accelerometer types to be used
• Can be used with line drive accelerometers or charge accelerometers (with Rion VP-80 3 channel charge amplifier)
• Data stored as csv files to compact flash
• Complies with BS 6472: 2008 and superseded BS 6472: 1992
• Complies with ISO DIS 8041 (2003), ISO 2631: Part 1 (1997), ISO 2631 Part 2 (2003), ISO 2631: Part 4 (2001)
• Frequency weightings wg, wb, wd, wm, wk, wc and wj can be independently set on each channel
• Measures rms, rms average, MTVV (maximum transient vibration value), VDV, crest factor and peak in x, y and z directions
• Measurement times:
  • manual start/stop
  • 1 - 30 seconds in 1 second steps
  • 1, 5, 10, 15and 30 minutes
  • 1, 4, 8 and 12 hours
• Auto-stores up to 9999 sets of data (rms average, MTVV, VDV, crest factor and peak) in x, y and z directions
• Auto-stores up to 12 hrs worth of 1 second logged data (rms, VDV and Peak) for each channel
• Manual storage for 50 000 datasets onto card
• Frequency Range with PV-83CW 0.5-80Hz
• Measurement Ranges (full scale) with PV-83CW 0.03, 0.1, 0.3, 1, 3, 10 ms-2
• Suitable Mounting Plates also available for the PV-83 and single axis accelerometers
