The invention provides a multifunctional tester, which comprises a plurality of indicator lights respectively corresponding to a plurality of air return systems; the automatic test module automatically polls the to-be-tested circuits of the air return systems, if the resistance value of the polled to-be-tested circuit is smaller than the reference resistance value and the to-be-tested circuit outputs an air return door feedback signal, the automatic test module drives the corresponding indicator lamp to be lightened, and otherwise, the indicator lamp corresponding to the polled to-be-tested circuit is not lightened; the manual test module is used for manually selecting a to-be-tested circuit connected with the tester and measuring the resistance value of the to-be-tested circuit, the manual test module is further used for connecting the tester and a tested air valve actuator, and the opening and closing states of an air return door corresponding to the air valve actuator are indicated through two indicator lamps in a plurality of indicator lamps; and the switching module is used for switching between an automatic test mode and a manual test mode.

    本发明提供一种多功能测试仪,包含:多个指示灯,分别对应多个回风系统;自动测试模块,其自动轮询多个回风系统的待测电路,若被轮询到的待测电路的电阻值小于基准电阻值,且该待测电路输出回风门反馈信号,自动测试模块驱动对应的指示灯点亮,否则该被轮询到的待测电路对应的指示灯不点亮;手动测试模块,用于手动选取与测试仪连接的待测电路,并测量该待测电路的电阻值,手动测试模块还用于连接测试仪和一个被测的风阀执行器,通过多个指示灯中的两个指示灯指示该风阀执行器对应回风门的打开、关闭状态;切换模块,用于在自动测试模式与手动测试模式之间切换。
