A biometric apparatus includes a weight measuring unit having a predetermined zero-point for measuring a load applied to a platform provided on a body of the biometric apparatus and outputting a load signal which indicates the load; a detecting unit for detecting the state of installation of the biometric apparatus and outputting a detection signal indicating the same; and a control unit connected to the weight measuring unit and the detecting unit for determining whether or not the state of installation is suitable for the zero-point reset of the weight measuring unit on the basis of the detection signal and whether or not the load signal is stabilized, and the zero-point reset is carried out when the control unit determines that the state of installation is suitable for carrying out the zero-point reset for the weight measuring unit and the load signal from the weight measuring unit is stable.
