Accelerometers have direction gaps between the package and the actual sensor in general. Conventional calibration methods of accelerometer, e.g. ISO standard, do not include this direction gap. This study proposes a new calibration method. This method uses newly proposed examination system with parallel link exciter mechanism. The mechanism rotates a test accelerometer. With this exciter, the posture of the accelerometer is kept constant against external coordinates. The input acceleration is stable because required torque of the mechanism is constant by counter weight. From the accelerometer output, a plane including actual sensor direction is detected by maximum value of the sine curve profile. The direction of actual sensor is the line of inter section of two measured planes. Actual sensor directions and sensitivities are experimentally examined.
