Accelerometer Calibration System SCS-ACV, according to ISO16063-21, is very suitable to middle-high frequency range (20Hz~10kHz). System include a vibration exciter BK4809, which is very suitable to small object. And more force rating type BK4808 is optional if needed. The standard accelerometer Endevco 2270 is good at calibration application (Resonant Frequency≥35kHz). System control and report generation are by software automatically.
