ABSTRACT:
An electronic scale is disclosed having a device for recalibrating the scale from time to time after the scale is moved from the factory to a site of installation in order to adjust the scale for physical and/or environmental operating conditions which are different from those which prevailed at the factory when the scale was originally calibrated after the completion of manufacture and which have an adverse effect on the accuracy of the scale if the scale is not recalibrated under these conditions. The scale is provded with a device which adds a predetermined fixed weight to the load cell of the scale at any desired time or interval of time, and an electronic count indicative of this weight at the site of installation is compared with an electronic count of the same weight taken at the factory and stored in a memory, and the digital readout of the scale is then adjusted by an amount which is the same as the ratio of the original count of the weight and the count thereof taken at the site of installation.
