A vibration monitor 1 for monitoring the exposure of an operator to vibration (eg caused by power tools, pneumatic cutting tools, machinery) can be attached to the operator's arm, wrist or leg (eg by a strap 16). A sensor measures the magnitude and frequency of the vibration and stores time and date stamepd data in flash memory. Data may be downloaded to an external unit (eg PC) via a serial communications link for analysis. A spectrograph is generated and the exposure of the user over a period of time is determined. The monitor may also include a temperature sensor. |
