The IET Labs ESI DP1211-1K potentiometers are precision decade resistive voltage dividers featuring the accuracy, high resolution and constant input impedance of the Kelvin-Varley circuit. The ESI DP1211-1K provides known voltage and current ratios for meter calibration, linearity checking, ratio measuring, synchro testing, computer standardization, and many other DC and audio frequency applications. The stacked dial configuration conserves space without sacrificing operating ease. Each unit occupies less than 45.2 square centimeters of panel space. Convenient in-line reading is provided by the esi Dekadial coaxial dial. The ESI DP1211-1K offers two decades plus a 100 division potentiometer. Exceptional stability and reliability are assured by the use of precision resistive elements. The ceramic switch decks are silicone-treated to improve insulation resistance, and the multiple switch contacts are of solid silver-alloy for long life and low contact resistance.
