Based on proposing to measure the inductance with RL transient analysis principle, a simple inductance measurement circuit was designed which make full use of STM32 microcontroller hardware resources and simple, efficient software design ideas, composed by a single chip microcomputer and a small amount common components, at the same time the PC program prepared through Labview platform, the instrument systematic errors was further reduced by error analysis from component selection and preparation of software in the end. The practical test and laboratory trials proved the measuring instrument has stable performance, easy operation, accuracy measurement, rapidly and clearly shown, meanwhile can automatically record many test results.
