Abstract

Disclosed is a method of recalibrating an electronic scale to maintain accurate weight measurements of a scale regardless of variations in the physical and/or environmental conditions under which the scale is operating between a site of origin and a site of installation which tend to adversely affect accurate weight. Also disclosed is method of obtaining an accurate indication of the weight of an article by an electronic scale at a site of installation regardless of variations in the physical and/or environmental conditions under which the scale is operating between a site of origin and the site of installation which tend to adversely affect accurate weight. Both methods are accomplished by recalibrating the scale to adjust the output of certain electronic control components to compensate for the difference in the physical and/or environmental conditions between the two sites which tend to adversely affect accurate weight indications of the scale.
