It is only when the correct voltages are applied to the A/C amplifier from the key inputs that the primary output (the A/C compressor relay) will be energised.
只有A/C扩大器上的电压是来自输入端的正确电压时，初级输出（即A/C压缩机继电器）才会被激活开启。
This will mean that, comparatively, there will be a larger volt drop across the resistance inside the amplifier and a smaller volt drop across the evaporator temp sensor.
这意味着，相对来说，通过扩大器内部电阻的电流压强降幅较大，通过蒸发器温度感应器的电流电阻压强降幅较小。
As there is a larger volt drop across the resistance inside the amplifier the voltage measured after it will be lower.
由于通过扩大器内部电阻的电流压强降幅较大，所以通过后的测试压强相对较低。
Once the circuit is broken the amplifier detects the voltage change in this circuit and de-energises the magnetic clutch relay, turning the compressor off.
一旦线路断开，扩大器探测到线路上的压强变化，就会停止电磁离合继电器运行，关闭压缩机。
