An LCR meter with a fast balancing method, with only one necessary measurement of voltages. The LCR meter uses to speed up balancing, separation in time measurement of a device under test (DUT), and other parasitic impedances, including a leakage impedance. The leakage impedance and the other parasitic impedances of a fixture and the LCR meter itself are measured during open/short calibration and saved to memory. The DUT is measured during measurement using already known parasitic impedances. This allows calculating balancing conditions using only one measurement of voltages.
