The Reader and Calibrator Unit for the Pulsar Noise Dosemeter system controls the individual dosemeter badges. The Reader Unit communicates with the dosemeter via an infra-red link.
The Reader Unit is required to calibrate the dosemeters prior to measurement as per the requirements of the Noise at Work Regulations and HSE requirements. Once you have fitted the dosemeter onto a workers shoulder (or helmet using the helmet mount) you are ready to start the dosemeter via the infra-red link. Once the noise exposure measurements have been taken the dosemeter is stopped in the same way using the Reader Unit.
