Abstract : The shock calibration of accelerometers is automated by feeding both the test signal and the reference signal to a computer. All pertinent parameters are entered in the computer prior to the test. The test program (software) produces a scaled and calibrated plot of the test signal and the inverted reference signal, and prints on the plot and the measured g values, the measured sensitivity of the test accelerometer, and the deviation from the manufacturers' stated sensitivity, in addition to the pertinent test and setup parameters. Successive tests can be averaged to eliminate statistical variations. A hard copy of the results is obtained when desired. Tem times more accelerometers can be calibrated and documented with the described automated procedure than was possible before. (Author)
