This work describes the new approach to the improving of the accuracy of the bridge impedance measurements. By this approach, the bridge balance in a wide impedance range uses the control of the phases of the aggregate of the cardinal signals only. The optimal structure and algorithm of the control of this aggregate of the cardinal signals is determined. Using this approach accurate impedance meters with low size and price are developed. In the limit, this approach gets us the possibility to develop fully integrated impedance meters. Report shortly describes universal impedance meters with phase control, their balance and calibration algorithms.
