PC Vibration Measurement System VibroMetra

Evaluation settings

 
Hand-arm vibration is usually not measured for a whole work shift but for representative intervals and works steps. To improve accuracy measurements can be repeated several times for averaging. However, VM-HAND can already display an estimated daily exposure value during measurement.  The daily exposure time can be entered.
