The normallyclosedcontact of the Model 7169A serves to discharge the capacitor after it has been measured.
在测量完成以后，7169A型的常闭接点使电容器放电。

When measuring the leakage current with this setup, the voltage bias is applied to all the diodes simultaneously through the normallyclosedcontact of each relay.
当利用这一配置测量漏流时，通过每个继电器的常闭触点同时向所有的二极管施加偏压。
