The invention relates to an electronic personal weighing scale (1) which can be used horizontally and stored in any position. The invention consists of a base (3) provided with feet (30, 31, 32, 33), a display (7) for displaying the weight measured and a weighing circuit (20) for measuring the weight of a person positioned on the base, said circuit including at least one weight sensor (22) and a zero calibration device. According to the invention, the weighing circuit (20) takes weight measurements at time intervals T and detects a change in the position of the scale when a weight variation in absolute value ?P between two successive measurements is between a stored minimum value Pmini and a stored value Pmaxi, said weighing circuit (20) triggering the start of a zero calibration cycle after each position change detection. |
