The dosimeter (20) has a fixing unit provided for fixation of an acceleration sensor (21) at an arm i.e. wrist joint, of a user. A time recording unit (26) is provided for recording load of the user based on vibration that is detected by the acceleration sensor. The recording unit compares detected vibration with a threshold, and records duration of the vibration that is larger than the threshold. The time recording unit comprises a memory module (27) for storage of standard load that is determined by an analysis device (58). An independent claim is also included for a method for detection of a vibration load in the hand tool machine. |
