Abstract
A method of recalibrating an electronic scale is disclosed which causes the scale to indicate accurate weight measurements 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 effect accurate weight. The method utilizes the removable platter of the scale as a fixed weight of indeterminate amount which is used to calibrate the scale at a site of origin under controlled physical and/or environmental conditions and to recalibrate the scale at a site of installation at which the physical and/or environmental conditions may be different from those that prevailed at the site of origin. Also disclosed is a method of obtaining an accurate indication of the weight of a mail piece placed on the platter of the scale at the site of installation regardless of the variations in physical and/or environmental conditions under which the scale operates, this method being an extension of the method for recalibrating the scale.
