ABSTRACT:
A voltage divider used to supply multiple reference voltages is energized electrically, in shunt, by a constant voltage generator and, in series, by a constant current generator. The magnitude of current supplied by the constant current generator determines the voltage drops across successive resistor stages of the voltage divider, while the magnitude of voltage supplied by the constant voltage generator determines the voltage level, with respect to ground, of the voltage-divider tap to which the constant voltage generator is connected. Since these two generators are independent of each other, it is possible to independently control the range and zero point settings of a voltage divider.
