Before starting the measurement, place the RAD7 in a dry, radon-free atmosphere to clean the instrument gas circuit for a period of time. During the cleaning process, use a large laboratory drying cylinder. And the small drying stick does the actual measuring. First connect the filter to the air inlet port of RAD7 (refer to the RAD7 operation manual), and then connect the large drying cylinder to the filter. After cleaning the RAD7 air path in clean and dry air for 10 minutes, press the [MENU] key, then press the [ENTER] key twice to enter the status window, and press the right arrow key twice to view Check the relative humidity. If the relative humidity has not dropped to 6%, clean it for a while. In order to effectively dry, after the first 10 minutes of air line cleaning, connect the air outlet of RAD7 to the inlet of the drying cylinder to form a closed loop. This allows continuous drying of the RAD7 without the need to introduce fresh air.
If the RAD7 has not been used for a period of time, or the hose connecting the air inlet and outlet has been disconnected, it will take longer to dry the air path, at least 30 minutes. Once the drying process is completed, it only takes 10 minutes to clean the gas line during each measurement.
