According to the problem when displaying voltage-ampere characteristic of diode by oscillometric method,we put forward an improved method. Using the Hall current sensor solves the principle defect on origi-nal circuit. Analog and experimental results show that the improved detection-circuits are better on the oscillo-scope display and are easy to regulated,and the voltage-ampere characteristic of diode is showed more accu-rately.
