LOAD COMPARISON SCALE

A scale for quantitatively determining an unknown sample includes a pan for holding a known sample and another for an unknown sample. Scale deflection due to the known sample is translated into a representative electrical signal and coupled to a display device, as for example a digital voltmeter by a potentiometer. The potentiometer is adjusted so that the reading on the digital voltmeter corresponds quantatively with samples in the known sample pan. The known samples are then removed, and the unknown sample is placed on its corresponding pan. The deflection of that scale is likewise translated to an electrical signal representative of the deflection and coupled to the digital voltmeter through the aforementioned potentiometer. The reading on the digital voltmeter will then correspond to the quantity of the unknown sample.
