FIELD: measuring devices. SUBSTANCE: momentary voltage at measured element is compared to momentary voltage at active reference resistor R directly after power supply was turned on. Active reference resistor is connected in parallel to measured element. Then time interval Tp from power supply turn-on to matching of voltage at R with voltage at L or C is measured. L or C are calculated according to equations which do not depend on value and slow non-stability of power supply. EFFECT: increased precision, simplified process of measuring. 3 dwg
