The verification of the accuracy and repeatability of transducers and measurement electronic systems is called calibration. Vibration transducers are calibrated by subjecting them to a known motion and accurately measuring the electrical output. They are normally routinely calibrated at one-year intervals, and more often if they are subjected to damaging stresses.
