摘　　要：文章首先对DZN2土壤水分观测仪的系统结构、硬件组成及工作原理进行了详细阐述,其次介绍了该设备的故障诊断流程和方法,以期减少因使用或维护不当而造成的设备性能衰退,减少野值的产生和缩短设备的维修时间,提高设备运行的可靠性和数据的可用性。DZN2 instrument for Soil Moisture Observation was used widely in the monitoring of soil moisture storage capacity and changing rules, But in the course often had malfunction like outliers and error was too large. For such failure phenomenon, the paper first introduced the system architecture, hardware components and the working principle of DZN2 instrument for Soil Moisture Obser- vation. And then it introduced the process and method of failure diagnosis, especially that for the weighing unit and processing unit of the instrument. In order to reduced device performance decline due to improper use or maintenance, reduced outliers and shorten re- pair time of the equipment, improved reliability and availability of data.
