| Abstract: | In this article, the magnetic balance is achieved through the adoption of phase locking trace. Both DC and low frequency and medium frequency AC are measured in an isolated way. The degree of stability and accuracy of measurement are achieved by making use of temperature compensation and the nonlinear compensation of magnetic circuit. |

| Keywords: | phase-locked loop isolation measurement nonlinear compensation magnetic balance |
