Abstract
There is disclosed an electronic scale which may, for example, be used as a bathroom scale, medical room scale, or otherwise. The scale provides a digital display of the weight of an object placed or positioned on a weighing platform and can provide said display in terms of the conventional system or the metric system by varying the time base or gate as applied to a counter. The counter has another input which provides a frequency related to the object's weight; which frequency is counted in accordance with the duration of the time gate, to enable a digital display of the weight. Apparatus is shown for providing a time base for the scale and employs two voltage to frequency converters, one to provide a frequency related to the weight of an object and the other to provide a time base; both of which vary according to supply fluctuations. The circuitry provides a number of pulses to the counter indicative of the true weight and independent of the supply voltage.
