MSP430F169 microcontroller was the core components of control and measurement function of an electromagnetic relay characteristic parameter tester. The tester also included DC power module, power amplifier module, constant current source module, keys, and digital tube display module. The tester could test the data of 943-1C-12DS electromagnetic relays including the minimum pull-in voltage, maximum release voltage, relay coil voltage rating when the pull-contact time, release time as well as the contact value of the contact resistance. The system could complete automatic measurement parameters to achieve all the basic requirements of design. And all of the test data was displayed through the 74HC573 digital tube.
