A method for automatically zero balancing an electronic scale includes disabling the display from displaying a 'Scale Ready' logo, taking a number of readings from the scale when no weight is placed on the scale, obtaining an average reading for a zero weight condition of the scale by dividing the sum of the readings by the number of readings taken, detecting when two consecutive average readings are within a first predetermined limit, enabling the display to display the 'Scale Ready' logo indicating the scale is ready for a weighing operation, taking a number of readings from the scale in response to the displaying the scale ready logo, blanking the display when the readings taken are not within a predetermined value of the zero balance readings, and removing the scale lid from the scale and cleaning the scale to remove dirt or other impediments from the scale in response to the blanking of the display.
