Voltage Measurement: Model 98113 Low-thermal Reversing Switch

The Model 98113 Low-thermal Reversing Switch is a low cost, easy to use device that is designed to mount directly on the output terminals of most commonly used Zener DC voltage reference standards. Its design assures thermal equilibrium between the Zener reference terminals and the contacts of the switch. Its low-thermal reversing action assures that the mean value of forward and reverse measurements is the most accurate possible measurement of the Zener reference voltage.
