SD-3A型自动测氡仪检查标定中应注意的问题

Some Problems in the Examination and Calibration of the SD-3A Auto-Radon Monitor

本文以安徽省庐江台在日常的维护和标定工作中所取得的数据为依据,结合多次检查标定的经验,简述了SD-3A型自动测氡仪在日常观测和检查标定过程中应特别注意的几个问题,如仪器工作方式的选择、及时调整仪器工作高压、仪器避光问题、标定气路选择等,文章分析了导致这些问题出现的原因及对观测结果的影响,并给出了正确的操作方法,确保仪器产出的数据真实、连续、可靠。

This paper is based on routine maintenance and the data from calibration work in Anhui Lujiang Seismic center, combined with multiple check calibration experience. Some problems in the observation and inspection calibration process of the SD-3A automatic radon monitor are briefed, such as the choice of working mode, timely high-pressure transfer of the apparatus, equipment light, calibration gas path selection. The causes of these problems and the impact on the observed results are analyzed, and the correct methods of operation are given to ensure that the data output are real, continuous and reliable.
