摘　　要：通过对龙岩台VS型垂直摆倾斜仪防雷改造后,日常观测资料正常,但标定时出现幅度异常增大的问题进行分析,经多次试验,发现标定异常现象是由信号线路问题造成的而非安装了防雷器。By lightning transforming to VS vertical pendulum tiltmeter at Longyan Seismographic station,it shows that daily observation data is normal,but during calibration,the amplitude is abnormal which is increasing.Through analysis and repeated tests,it reflects that the abnormal calibration phenomenon results from the signal line problems rather than installation of lightning protection device.
