[0002] The servo is mainly composed of a motor, a reduction gear set, a potentiometer, a control circuit, a housing, and a steering wheel. The servo is a small and powerful motor that can convert electrical signals into mechanical motion. It is usually used to control the steering or other actions of model airplanes, robots, cars, etc. The servo can be used as a basic output actuator in micro-electromechanical systems and model airplanes. Its simple control and output make it very easy to interface with the single-chip microcomputer system.

[0003] After checking the public (announcement) number: CN101726425B, a servo tester is disclosed. By using the servo tester, the motion status of the servo connected to it can be seen at a glance, which plays an important role in future programming. The signal parameters of the servo can also be directly read out through the values ​​displayed on the digital tube, and the corresponding motion function can be compiled through these parameters. After a long period of research and development, a two-channel servo tester can now be provided, which undoubtedly provides strong technical support for the robot research and development and production links. The servo tester can be used in many occasions, not only limited to the field of robots, but also in aviation models. The servo tester can be used to control various valve servos.
