Excerpt from Practical Methods for Calibration of Potentiometers
Practically all ratio sets and resistive voltage dividers contain a resistance circuit terminated on each end by a binding post connector. A simple slide-wire represents the most readily visualized ratio set or voltage divider. The sliding contact is free to travel from one end of the wire to the other. The ratio of the resistance of the wire on one side of the sliding contact to the resistance on the other side can be varied continuously as the slider is moved along the resistance wire. These two resistances, one on either side of the slider, can be used to form two arms of a Wheatstone net or bridge circuit. It is such a circuit that is used to calibrate potentiometers. At least one and commonly two of the other bridge arms consist of selected portions of the potentiometer under calibration. We may also think of the slide wire as a ratio set giving the ratio of resistance of either arm of the slide-wire to the total slide-wire resistance. Likewise, the slide wire may be considered as a voltage divider. A fraction of the voltage impressed between the two slide-wire ends appears between the slider and one end, while the remainder appears between the slider and the other end. These concepts facilitate the visualizing of the operation of a ratio set.
