Abstract
To correctly recognize the 0 kg state and to reduce the time required for weight measurement. A body composition meter including a load cell for measuring a weight includes step of performing a measurement of an output value of the load cell in an initial state on which a measuring target does not ride, a storage unit for storing a plurality of measured output values of the initial state, step for creating 0 kg reference value data when variation of the plurality of output values in the initial state is within a predetermined range, and step of measuring using the initial reference value when measuring the weight with the load cell.
Claims10
A weight measuring device including weight measuring unit that measures weight;
- the weight measuring device comprising:
- an initial value measuring unit that carries out a measurement of an output value of the weight measuring unit in an initial state on which a measuring target does not ride;
- a storage unit that stores a plurality of measured initial values;
- an initial reference value creating unit that creates an initial reference value when variation of the plurality of initial values is within a predetermined range;
- and
- initial reference value application unit that measures using the initial reference value when measuring the weight of the measuring target with the weight measuring unit;
- wherein
- the initial reference value creating unit stores the created initial reference value in the storage unit;
- and
- the initial reference value application unit has a configuration adapted to measure the weight of the measuring target using the initial reference value when the initial reference value is stored in the storage unit and includes a measurement initial value application unit that measures the weight of the measuring target using the initial value measured with the initial value measuring unit when the initial reference value is not stored in the storage unit.
A weight measuring method for measuring a weight by a weight measuring device including a weight measuring unit;
- the method comprising the steps of:
- performing a measurement of the weight measuring s unit of an initial value on which a measuring target does not ride with an initial value measuring unit;
- storing a plurality of measured initial values in a storage unit;
- creating an initial reference value by an initial reference value creating unit when variation of the plurality of initial values is within a predetermined range, and storing the initial reference value in the storage unit;
- measuring weight using the initial reference value when the initial reference value is stored in the storage unit by an initial reference value application unit when measuring the weight with the weight measuring unit;
- and
- measuring a weight using the initial value measured with the initial value measuring unit by a measurement initial value application unit when the initial reference value is not stored in the storage unit.
