After a brief review of the electromechanical functioning of the piezoelectric accelerometer, factors affecting its dynamic response characteristics and therefore the validity of vibration measurement are discussed. Consideration is given to variables such as shunt resistance and capacitance, mounting methods, base bending, cable noise, ground- loop currents, and environmental effects. Approved accelerometer mounting techniques that will ensure the accuracy and repeatability of the measurement are also described.
