- Abstract. The most important equipment in a calibration system used to calibrate vibration transducers is the exciter used for generating motions. A perfect exciter when excited in a geometrical direction, should provide a stable, single directional and distortion free vibratory movement, without generating any additional source of uncertainty. Unfortunately, this condition cannot be easily realised in real situation. Most commercial exciters experience high limitations when used during sensor calibrations. The accelerometer will be sensitive to any movements generated along its input axis when the seismic is not symmetric to the input axis. The parasitic exciter's features will undesirably affect the accelerometer's response, which may degrade calibration's accuracy.The paper will show how the exciter's total transverse motion, amongst other effects was resolved into vectors (x- and y vectors) in representing the parasitic effects that will influence the accurate calibration results of the accelerometer. These vectors were calculated and quantified as the error affecting the accelerometer results. The error was added to the results in the form of UoM contributing to the accelerometer's sensitivity results. A model will be used to verify the total uncertainty to be added to the results.
