因微弱的模拟电压信号特别容易受到外部干扰，所以一般需要用屏蔽电缆，而且配线距 离
尽量短，不要超过 20mo在某些模拟信号受到严重干扰的场合，模拟信号源侧需加滤波 电容器
或铁氧体磁。Because the weak analog voltage signal especially been outer disturbed easily, so,
generally need shielded cable, and the cable distribute distance should do best to be short, not exceed
20m. The analog signal source side need additionally add filter wave electric capacitor or iron-oxygen
magnetism in the place where some analog signals seriously disturbed.
