ESI RV722 Overview
The RV722 Decade Voltage Divider is a precision resistive voltage divider which uses the Kelvin-Varley circuit. Input terminals provided for the calibration of each individual decade against a standard ratio. Seven-decades, resolution of 0.1 ppm steps, 10,000,000 divisions. Long -term direct reading accuracy is ?1 ppm. Input resistance of 100 kohms (?50 ppm).
