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.

Paperback. Zustand: New. Print on Demand. This book highlights various approaches to calibrate potentiometers, with a focus on the Universal Ratio Set method. Potentiometers are widely utilized for accurate voltage and current measurements in scientific research and industrial applications. The author, an expert in the field, provides a comprehensive analysis of potentiometer circuitry, particularly as it relates to calibration. Beginning with an introduction to potentiometer basics, the book delves into the principles behind the Universal Ratio Set and its role in calibrating potentiometers. It then discusses constant current, Lindeck, and combination potentiometers, offering detailed instructions and examples for their calibration. The book emphasizes the importance of precise resistance measurements and thorough analysis of circuit components to ensure accurate calibration. Through a blend of theoretical explanations and practical guidance, the author aims to equip readers with the knowledge and skills necessary to calibrate potentiometers effectively. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
