我国引进的DFS-V数字地震仪是美国得克萨斯仪器公司制造的。仪器结构比较复杂,它具有体积小、重量轻和耗电省的特点。但由于它采用了大量的CMOS集成电路,因此,比较娇嫩,维修起来也困难些。从DFS-V数字地震仪在野外工作中所发生的一些故障来看,一部分是属于仪器本身自然发生的故碍;而有相当一部分故障则是由于操作不当而引起。为使这种仪器能够更好地发挥作用,尽可能减少人为原因造成的故障,这里仅就我们在实际工作中碰到
DFS-V digital seismograph introduced by our country is made by Texas Instruments Company. Instrument structure is more complex, it has small size, light weight and power saving features. However, because it uses a large number of CMOS integrated circuits, so more delicate and more difficult to repair. Some of the faults that occur in the field work of the DFS-V digital seismograph are partly due to the natural occurrence of the instrument itself; a considerable part of the failure is caused by improper operation. In order for this instrument to work better and to minimize human-caused causes of failure, here we are only talking about what we are actually doing
