Abstract
There is provided a weighing instrument with body fat meter which can compensate for variation in contact impedance between a human body and a measuring electrode due to wearing socks or the like. The weighing instrument comprises a constant-voltage power source as a current power source for measuring a bioelectrical impedance and a current measuring device installed between the constant-voltage power source and a voltage supply terminal to measure an internal influent current and determine an internal impedance on the basis of the measured internal influent current and a potential difference between voltage measurement terminals.
