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.

摘 要：以MSP430F169单片机作为控制和测量的核心部件，辅以直流稳压电源模块、功率放大电路模块、恒流源模块、按键和数码管显示模块等组成一个电磁式继电器特性参数测试仪，完成对943-1C-12DS电磁式继电器最小吸合电压、最大释放电压、继电器线圈电压为额定值时的触点吸合时间、释放时间以及触点接触电阻值的测试，该系统能够实现成套参数自动测量，所有测试数据通过74HC573数码管进行显示。

The main features of the system are: the communications line is not only used for data transmission but also responsible for the system control and management; only one analogue to digital converter is needed for the whole system; a digital trimmer which is analogous to the adjustable resister in function is installed to each sub—system.

The sample comprised 25 patients with the first premolar removed during orthodontic treatment. Digital models and lateral cephalometric records were taken pre- and post- treatment. We chose two kinds of regional superimposition methods on the digital models (One was the mesial zone of the third primary ruga and regional palatal vault, the other was the palate) and Baumrind's best-fit for cephalometric superimposition. The amounts of incisor and molar movement were measured and a comparative study was performed.
