ABSTRACT:
A method of improving the accuracy of scale readings featuring exciting the molecules of the supporting spring and clamping structure of the scale. The purpose of this excitation is to reduce the effects of hysteresis, creep and drift upon the measured load. Exciting the molecules of the support spring causes the scale to reach its stable state of stress much more rapidly. This results in obtaining more accurate weight readings for a load being weighed.
