The components, main functions, working process and research development of modular formation testers are briefly introduced in the paper, which focuses on the fundamental principle of fluid identification.

By adopting new principle,advanced power electronic technology and information technology,the conventional configuration mode of serial combining separated components and modular integration is broke through, multiple functions of circuit breaker,contactor,thermal relay,starter,counter,and current display are integrated into one electromagnetic apparatus unit.

Modular teaching mode refers to the employment-oriented, practitioners should have a comprehensive ability to post as the center, according to the need for capacity-building to set curriculum modules, organize modular teaching materials, and build modular experimental practice bases, and implement the theory of production and work process and practice of teaching as a teaching mode.
