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.
Evaluation settings

Preliminary assessment

1. Preliminary assessment
Allows evaluation and color change of the measuring result already during the measurement. This feature is only available for triaxial measurements.

Daily exposure time

2. Daily exposure time
This is the exposure time per day by the currently measured activity needed for preliminary A(8) calculation.
