The method of circuit bridge for measuring resistance is one of the very important contents in experiment physics teaching. Taking DC bridge for example, by using LabVIEW through programming, CTL interface beautification, local variables and Property Node setting, the experiment of measuring resistance by DC bridge is simulated. In the process of development, the galvanometer current formula in the Wheatstone bridge and Kelvin bridge is unified, the calculation is carried out with matlab. The system realizes the whole process of experiment operation, processing and simulation of experimental data and expression of complete experimental results in the same simulation software.
