Application
- • VM-BODY: Measurement of whole-body vibrations in vehicles, railways, construction machines, buildings etc. to EN ISO 263
• VM-SHIP: Measurement of whole-body vibrations on board ships to ISO 20283-5 (formerly ISO 6954)
• Evaluation of comfort and potential health risk
Properties
- • Contains weighting filters Wb, Wc, Wd, Wj, Wk and Wm to ISO 8041 (VM-SHIP only weighting filter Wm)
• Measurement of 3 axes simultaneously
• Display of interval RMS for three axes, VM-BODY also maximum RMS (MTVV) and crest factor
• Calculation of total vibration value Ahv
• Protocol and export function
• High reliability by text based and graphical user guidance
• PC based measuring system using the IEPE / USB interface M302 and IEPE compatible accelerometers
• The instrument has a clone function, i.e. several program windows can be operated simultaneously with different settings
• Offline measurement with stored data
• Evaluation based on limit values according to standards
• Free update service from our website www.MMF.de
• Available as kit: VM-BODY Kit / VM-SHIP Kit
