FIELD: electrical technics. SUBSTANCE: method is based on transforming parameter to be measured into the current through galvanometer. Resistance value is directly transformed into current variations by the aid of amplification tube, in which, between the grid and cathode, galvanometer is put in, and as power source to power the circuit, thermal electromotive force of electron emission from the hot cathode is utilized. EFFECT: simplified resistance measurement. 1 dwg
