Abstract
An electronic balance includes a system in which a current supplied to a force coil in response to a load applied to the balance is caused to alternate in direction at such a time interval as to permit of no oscillations and in which the measured value is obtained by subtracting the product of the current in the negative direction and a time fraction t.sub.2 for which the same flows from the product of the current in the positive direction and a time fraction t.sub.1 for which the same flows, the sum of said time fractions t.sub.1 and t.sub.2 being equal to each of said time intervals.
