PURPOSE:To improve the accuracy of measurement, by detecting the electrostatic capacity or inductance generated in a sensor as a parameter of an oscillator, converting the oscillation frequency thereof to the weight value of a weighing object and displaying the same digitially. CONSTITUTION:If the weight value of a weighing object X is assumed to exist between addition and division weights W1 and W2, the operator turns a knob 16 by one division, then only the weight W1 among the W1-W5 is lifted. At the same time, a changeover switch 23 changes over and the weight value of only the weight W1 is displayed directly. For the remaining weight, the change component by the unbalance state of a balance beam 2 is changed to the change in electrostatic capacity or inductance and is added to the weight W1 through an oscillator 20 and a converter 21. |
