title: Real-Time Calibration of Velocimeters Using a Reference Standard
abstract: All digital seismic recorders of the Crimean seismological network are equipped with sensors inherited from galvanometric recording. Long-term channels are equipped with SKD sensors, and shortterm channels are equipped with SM3, SKM, SKH, and S-5-S sensors. The instruments periodically undergo preventive maintenance due to wear and long operation life. There are no equipment specialists at peripheral stations. All necessary installation, preventive maintenance, adjustment, and calibration work i
