Abstract:
A method for testing components of a device using an adjustment algorithm which modifies itself to adjust a first parameter of a selected device component based on a second parameter of the selected device component which is set to a predetermined value, said first parameter includes a predetermined tolerance, comprising the steps of:(a) obtaining each of a high limit for said first parameter, a low limit for said first parameter, a high measurement for said second parameter and a low measurement for said second parameter, from a prior implementation of the adjustment algorithm to another device component; (b) applying said first parameter test value to the device and measuring the resulting value for said second parameter; (c) calculating a first parameter error by the algorithm (said second parameter predetermined valueâ€”said second parameter resulting value) * (said first parameter high limitâ€”said first parameter low limit)/(said second parameter high measurementâ€”said second parameter low measurement); (d) where said first parameter error is less than said tolerance, setting said first parameter test value to an adjusted value for said first parameter, whereby said first parameter adjusted value generally approximates said second parameter predetermined value when said first parameter adjusted value is applied to the device and said second parameter is measured; and (e) where said first parameter error is one of greater than and equal to said tolerance, calculating an adjusted value for said first parameter by the algorithm (said first parameter test value+said first parameter error)/an algorithm factor, where said algorithm factor is a positive number of at least 1.
