Design of Parameter Tester for Electromagnetic Relay
Abstract：ARM microprocessor STM32F103VBT6 is used to be the control core in the design of parameter tester of electromagnetic relay in order to eliminate man-made and line interference and improve testing accuracy and speed.Results can be automatically measured through keyboard selection and output on LCD,through data printing as well as stored in flash disk.In addition,the standard parameters of the relay are stored into the ARM memory cell in advance.Thus,the instrument and the tested samples will not be damaged when there is a misuse or serious fault of relay.Testing results show that accuracy of measurement amounts to 4.5%.
