If the beeper beeps the reception is jammed or the voltage of the battery is too low. 如果蜂鸣器发声，表示接受受到了干扰或者电池电压过低。
VCM represents the common-mode voltage, which contains no useful information about the measurement and could in fact reduce the measurement accuracy. 象电池电压监视的应用，共模电压是测量系统所隐含的。
In this technology, entering the electric tank brine mass is this technology key , it has important effect to ionic membrane life-span , slot voltage and current efficiency. 在这项技术中，进入电解槽的盐水质量是这项技术的要害，它对离子膜的寿命，槽电压和电流效率有着重要的影响。
