General-nha Beta & Gamma.docx

General: 1. The Dose Rate, the current time, latitude and longitude, and battery level are displayed on the LCD screen. The measurement values are also displayed by the bar graph. 2. The measured Dose Rates are stored as time series data according to the Trend Data Storage Cycle. 3. The measuring position coordinates along with time are displayed. 4. By connecting the USB Cable, the data can be transmitted to the PC and the various parameters can be set by utilizing the optional Communication Software. 5. The stored Dose Rate Data is transmitted to the PC with Bluetooth. Radiation detected Detector Energy Range
