| Abstract: | Aiming at the problems of manual testing method for self- limiting heating cable' s performance with bad efficiency and greater error, automatic testing system is developed. In this system AD590, power sensor WBP412 and Simulation multiplier are used to test temperature, power and voltage.The result indicates that this testing system has features including operating easily, high efficiency and precision, whose relative errors being less than 2%. |
