目前,SK仪的ZY—6记录器多用角锥摆钟作动力源。由于角锥摆钟置设于室暗,工作不便,并且故障多,调整和维护困难,易造成记录停记和断记,又走时误差大、不稳定,因此直接影响地震资料的质量。为消除这些缺点,经反复试验验证,将交直流自动切换的JK—79晶控钟取代角锥摆钟可得到令人满意的效果。 At present, SK instrument ZY-6 multi-angle pyramid pendulum clock as the power source. As the pyramid pendulum clock placed in the dark room, work inconvenient, and more problems, adjustment and maintenance difficulties, easy to cause the record to stop recording and broken down, and when the error is large, unstable, and therefore directly affect the quality of seismic data. To eliminate these shortcomings, after repeated tests to verify that the AC-DC JK-79 crystal clock automatically replace the pyramid pendulum clock can be satisfactory results.
