[my country's First Strong-Motion Accelerometer Calibration Device Approved with an Error of No More Than 0.02%] Recently, the State Administration for Market Regulation approved the establishment of the first strong-motion accelerometer calibration device in China by the First Monitoring Center of the China Earthquake Administration, providing strong metrological support for the accurate monitoring of "Earth's pulse." This device combines superior vibration simulation performance with ultra-high measurement accuracy. It can simulate a maximum vibration intensity equivalent to a car accelerating from a standstill to 216 kilometers per hour in 2 seconds. Simultaneously, it can accurately reproduce ground vibrations caused by earthquakes of magnitude 1 to 8, ensuring that equipment calibrated by the device can respond stably and reliably to earthquakes of varying intensities. Furthermore, the device's measurement error does not exceed 0.02% of the earthquake magnitude, far below the limits of human vibration perception, which helps improve the scientific analysis and assessment of earthquake destructive forces.
