DZ型自动标定仪是根据目前普遍使用的分段标定方法研制出来的一种小型台站辅助设备。该仪器主要用于标定短周期或中长周期地震仪记录系统的幅频特性、阻尼特性和道间感应。也可以用于校准同频段其它测震设备。它与使用分立式标定设备相比,具有结构简单、幅值稳定、操作方便等优点。施加触发信号,便能自动输给地震仪14组等幅或微分双向变频信号。使用这种标定装置,不仅方便可靠,而且提高了标定精度和效率。该仪器由数字钟控制,可实现定时标定,便于随时检验地震仪特性。仪器主要技术性能如下:
DZ automatic calibrator is based on the currently widely used method of sub-calibration developed a small station auxiliary equipment. The instrument is mainly used to calibrate the short-period or medium-long period seismic amplitude-frequency characteristics of recording systems, damping characteristics and sensors. It can also be used to calibrate other seismic equipment in the same frequency band. Compared with the use of discrete calibration equipment, it has the advantages of simple structure, stable amplitude, easy operation and so on. Apply the trigger signal, it can automatically lose seismograph 14 sets of amplitude or differential two-way frequency conversion signal. Using this calibration device, not only convenient and reliable, but also improve the calibration accuracy and efficiency. The instrument controlled by the digital clock, can be timed calibration, easy to check the seismograph at any time characteristics. The main technical performance of the instrument is as follows:
