The plate type Wheatstone Bridge is widely used in college physical experiment, since it can simply and intuitively reflect the characters of bridge circuit, and in the meantime it is easy to process and observe. In this paper, the causes of two severe faults occurred in the Wheatstone Bridge experiments had been analyzed. To avoid these faults, several improved methods had been put forward. According to the actual effect, we found that all these improved methods were feasible. In addition, our methods are beneficial to cost saving and reducing the workload.
