各种各样的装置都需要进行通断性检查，包括电缆成套件、印制板和连接器，以确保这些元件具有预期的连续通路。
Continuity checks are typically performed on a variety of devices, including cable assemblies, printed circuit boards, and connectors, to ensure these components have a continuous path where desired.
既然通断性测试往往涉及到多导线装置，因此利用一套开关系统将欧姆表自动连接到每根导线就非常有用。
Given that continuity testing often involves multi-conductor devices, a switch sys tem is useful to connect the ohmmeter to each conductor automatically.
