Abstract:
Two main impact factors on accuracy of electronic balance are discussed based on its working principle:acceleration of gravity and temperature variation.Through analysis of interacting variables in acceleration of gravity and electronic balance measurement results,the method of builtin standard weight compensation and its shortages are brought forward and attach the compensation method on weight calibration.The impacts on temperature change for the electronic balance measurement are analyzed,which proposes a method to eliminate these factors.
