If the electric relay A is not energized,there is electrical current flow or logic continuity through the normally closed contacts,so output relay coil is energized or On.

If电继电器A不通电，有电流流或逻辑的连续性，通过通常关闭的接触，使输出继电器线圈通电或On。

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.
