A second set of switches (on the Model 7158) connects each capacitor to the pico ammeter after a suitable soakperiod.
第二组开关(7158型)在经过合适的平稳时间后将每个电容器连接到皮安计。

The leakage current will decay exponentially with time, so it's usually necessary to apply the voltage for a known period (the "soak" time) before measuring the current.
泄漏电流随时间呈指数衰减，所以通常需要在一个已知的时间期间内施加电压(浸润时间)，然后再测量电流。

After a specified "soak" period, energize Ch. 21 to measure the resulting current.
