Methods： The production and control of testing signals, the collection and processing of electrocardiograph data, and the automatic switching techniques about work state of electrocardiograph were seriously studied, so the main hardware and basic software of automatic measurements technique were set up. Results： Automatic test technique could finish all the basic parameters of electrocardiograph. Conclusion： These problems of time-consuming, human-consuming, and paper-consuming are expectedly solved in the future.
