The RDS-40WE is a Digital Handheld Dose Rate Meter designed for use by personnel who may be exposed to gamma and/or X-ray radiation in their work. RDS-40WE provides either sequential or fi xed dose rate alarming system (values are programmable by the CSW confi guration software via IrDA link) and the possibility to store dose rate events into the histogram memory of the meter.
The use of the RDS-CSW software (Mirion product # 1233-246) is required for downloading the data into a PC via IrDA port.
RDS-40WE is microprocessor controlled. The user interface consists of one push button and an easy-to-use menu structure that displays information in the LCD of the meter. The six digit display shows the dose rate and various messages. Diff erent alarm situations are indicated by a combination of audio-visual eff ects in the LCD and a buzzer (dose rate, dose , low battery, defect, dose rate overfl ow).
