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.
电流在反馈电阻上产生的电压超出设定值时，IR 2132启动内部保护电路，关断输出通道，实现电流保护。
When the voltage on the feedback resistance over the designed value, the inside protection circuit was operated and the output channels were cut in IR2132 to achieve current protection.
下为高侧和低侧输出电压闭锁电路内部防止IX 2120 B从分立功率IGBT转动，直到有足够的栅极电压。
Internal under voltage lockout circuitry for both the high side and low side outputs prevents the IX2120B from turning on the discrete power IGBTs until there is sufficient gate voltage.
LVDT输出信号的波幅与相位转换成与微控制器内部ADC兼容的形式，一般需要添加外部电路。
Conversion of an LVDT's output signals' amplitude and phase into a form compatible with a microcontroller's internal ADC usually requires additional external circuitry.
