将静电计置于电压模式，然后打开外部反馈，就把反馈电路从内部网络切换到连在前置放大器输出端的外部反馈网络上。

Placing the electrometer in the volts mode and then enabling external feedback switches the feedback circuit from an internal network to a feedback circuit connected to the preamp output.

当基准和反馈时钟信号的相位和频率相同时，PLL处于锁定模式，且PFD输出信号中不生成脉冲。

When the phase and frequency of the reference and feedback clock signals are the same, the PLL is in lock mode, and the PFD does not generate pulses in its output signals.

实施的多重反馈回路控制器，微电网可以输出高品质电源的电网连接模式下。

With the implementation of the multiple feedback loop controller, the Microgrid can export high-quality power under the grid-connected mode.
