Calibration of each accelerometer is accomplished by comparison to a NIST traceable reference. Using a UD Model APEX SL-C Digital Calibration Control System, a continuous calibration curve is plotted from 10-10,000 Hz., showing percent deviation of charge sensitivity as compared to the sensitivity measured at the 160 Hz. reference frequency.
