摘　　要：结合实际工作经验,总结了GMS-07综合电磁观测系统主机ADU-07e的主要结构特点,以及主机自检进行观测系统工作状态检查的情况,介绍该观测系统在野外观测过程中的注意事项,梳理常见故障的现象和排除方法;通过实例说明无法自检出的未接中心电极和磁道斩波器故障引起的资料异常。故障检测方法同样适用于GMS-07电磁观测系统常规大地电磁野外施工。Based on experience acquired in practical work,the authors summarize in this paper the main structure of the ADU-07 e and the problem as to how to check the status of the ADU-07 e from self test and especially sum up precautions for common trouble phenomena during field work and troubleshooting method for the operation of the GMS-07 comprehensive electromagnetic observation system.Practical examples illustrate abnormal data due to lack of ground electrode or chopper closure during recording data which cannot be checked from self test. The trouble detection method is also applicable to the GMS-07 system used in conventional MT exploration.
