Based on the analysis of TH2828S broadband LCR digital electric bridge measurement principle, in combination with the relevant theories of non-linear magnetic core inductance coil, the measurement data is analyzed by making a comparison test on different magnetic core inductance coils to find the measuring difference between two measuring instruments. By measur-ing the DC-free magnetization core inductor coil, the equivalent manner of the tester is selected according to the reactance. As fore the measurement of DC magnetization core inductor coil, an external ammeter is used to monitor the magnetizing current. By the method, the measurement error of the replacement instrument was eliminated, and the methods to measure different magnetic core inductor coils by the alternative instrument and to set parameters were also found out.
