AIM: To realize the interface of the hardware and software of an inductive impedance measuring system so as to lay a foundation for future measuring experiments. METHODS: The DAQ card was programmed with LabView to control the sampling, the pretreatment of the data and the measuring models. RESULTS: Based on the virtual instrument interface, a single coil measurement experiment of the relationship between conductivity and phase shift was conducted and the result corresponded well with the theoretical analysis. CONCLUSION: The virtual instrument interface based on LabView is suitable for the inductive impedance measuring system and it can be used to conduct measuring experiments and preliminary imaging experiments.
