После выпол ени  равенства (4) сираведL .. ,(б) ливость услови  достигаемого изменением тока /I (ю2 или LO) контролируетс  по отсутствию напр жени  на выходе нуль-индикатора 12. Если в качестве устройства 11 использовать интегрирующее, то выражени  (4), (5) и (6) иринИмают соответственно вид: В этом случае частотнонеза-висимость напр жени  достигаетс  изменением образцового индуктивного тока /;, а состо ние равновеси  - регулировкой /,.. Насто щий способ позвол ет сравнительно просто автоматизировать процесс измерени  при введении исполнительных элементов 13, 14 и 15, регулирующих соответствующие токи. П р е д м е т и з о б р е т е и и   Способ измерени  параметров параллельлого колебательного контура, основанный на сравнеиии тока, протекающего через измер емый объект с активным, емкостным и .индуктивмы .м токами, протекающими через образцовые элементы, отличающийс  тем, что, с целью упрощени  процесса измерени , изменением образцового активного тока устанавливают квадратурную зависимость между вектором разности сравииваемых токов и вектором папр жени  питани  схемы, затем изменением емкостного тока добиваютс  независимости от частоты выходной активной величины устройства, дифференцирующего разX токов, после чего регулиго тока схему привод т вafter which expression (1) takes the form: Е I i «iCa. ShgSo yr-J (, (L, - 17 from equality (3) it follows that the inequality of equality; X-. Xi Lj - bo can be controlled by achieving the dependence of the output voltage of He differentiating device on the frequency of the generator 7, where: nd) 2 (CoC02 - CfM 1) + 7 J-, (o) 6 and GdTP LX LO and TQ, Hz are the real coefficients characterizing devices 9 and 11. After the equality (4) has been fulfilled, the condition achieved by the change in current / I (S2 or LO) is monitored by the absence of voltage at the output of the null indicator 12. If the integrating device is used as device 11, then expressions (4), (5) and (6) irinimi respectively form: In this case, the frequency-instability of the voltage is achieved by changing the sample inductive current /; and the equilibrium state - by adjusting /, .. The present method makes it relatively easy to automate measurement process with the introduction of actuators 13, 14 and 15 that regulate the corresponding currents. Methodology Measuring parameters of a parallel oscillatory circuit based on comparison of current flowing through the measured object with active, ICs and inductors. The currents flowing through the model elements, characterized in that, in order to simplify the measurement process, by changing the sample active current, a quadrature relationship is established between the difference vector of the compared currents and the power supply vector of the circuit, then by changing the capacitive current, the frequency of the output active value of the device, which differentiates the times of the currents, after which the current regulation circuit is brought into
