Abstract
An automatic-calibration instrument to improve calibration accuracy of acoustic-emission (AE) transducers by one order of magnitude over commercially available equipment is described. The instrument facilitates calibration by automatically displaying the maximum value of the stress used to produce AE calibration pulses and the AE pulse. Low-noise amplifiers and filters are used to improve the sensitivity of the measurements by more than one order-of-magnitude over commercially available instruments, so that smaller signals can be detected
