<p>A method of calibrating the selectable trip points of an overload relay (10) wherein a neural network is used in the calibration process. The calibration method involves precisely positioning an indicia (30) comprised of a number of graduation marks or symbols each representing a particular trip point and having a range and spacing unique to the characteristics of an overload detection circuit of a particular overload relay. The indicia is calibrated with respect to predetermined positions of a trip point indicator (26) and fixed with respect to the predetermined positions of the trip point indicator. The range and spacing of the indicia graduations is derived from the neural network learned trip point values and from trip point values obtained from the particular overload relay being calibrated.</p> |
