New high-stability, low-noise silicon semiconductor devices and advanced solid-state circuit technology are the basis for this unusually stable voltage regulator.

The improved performance of the Model 2005 permits dial readout of the output voltage to five places. Interpolation of the last place is provided by a potentiometer with a resolution of 10 microvolts.

Conventional, more complex chopper techniques for DC amplifier stabilization are avoided by maintaining critical amplifier stages and a specially processed zener diode voltage reference in a temperature-controlled oven.

The design simplicity results in a low-cost unit, half the size and weight of comparable instrumentation.
