Abstract

1,155,946. Voltage measurement. LICENTIA PATENT - VERWALTUNGS G. m. b. H. June 15, 1966 [July 8, 1965; July 16, 1965], No.26624/ 66. Heading GIU. [Also in Division HI] Direct voltage measuring potentiometer for measuring very small voltages (down to 10<SP>-8</SP> v) free of thermo-electric errors incorporates a resistor network 4 whose resistance between fixed terminals 10, 11 is constant but which has adjustable taps 7, 8 through which constant current from a generator 9 is caused to flow, so that a variable resistance may be established in the constant current circuit. The voltage to be measured is connected in opposition to the voltage at a selected tap 16 of a potential divider connected in parallel with the resistor network between the fixed terminals, the voltage at the selected tap being adjusted to balance the voltage to be measured by adjusting the taps of the resistor network. Balance is indicated on a suitable meter.
