在用标准的外加电流阴极保护管线上用电流梯度法进行检测时，仪器往往不会受保护电流上谐波的影响，所以不将管线上的阴保电流断开是可以接受的，但当施加检测信号点与阴保站极近时，出于发射机的安全考虑，好断开管线上的阴保电流。在使用PCM的“皮尔逊法”(地面电场法或称用A型字架测量法)对管道的任一部分进行检测过程中，检测信号可能会发生明显的失真。

The uniform pressure band is generally set up every 300-500 meters on the pipeline. During the inspection process, it is hoped that all the uniform pressure bands will be separated and this will be done as far as possible within an adjacent 3-5 km range. For most of the oil field pipeline is difficult to do. In this way, the welding joint of the uniform pressure band is represented as a Breakpoint of the embalming layer, and some signals on the tested pipe will be transmitted to its adjacent pipeline; It is also possible that the signal is returned from a pipe through the joint. However, in most cases, the signal strength of the target pipeline is the largest. According to the signal strength of the target pipeline, it is still possible to distinguish the target pipeline to complete the corresponding detection.
