FIELD: electric measurement technology. SUBSTANCE: measuring converter has reference resistor, constant current amplifier, ampere-turns unbalance converter, which has ampere-turns unbalance converter, feedback winding connected to constant current amplifier through reference resistor, measuring and compensating windings. Compensating winding is made of individual sections with different number of turns. Outputs of the commutator are connected with sections of compensating winding. Reference current source is connected to input of commutator through controlled switch. Converter also has measuring converter, control unit and two analog-to digital converters which have inputs connected to output of measuring converter and to potential outputs of reference resistor. EFFECT: improved precision of measurement. 5 dwg
