When the electric appliance is in the working condition, the divider resistance generates pressure drop so to enable the emitting diode to illuminate. 反之,在非工作状态下,开关断电,压降消失,发光二极管不发光。
It is shown by tests that, the internal electric resistance, the response time from thickness to thinness, the response voltage under high ratio of mixture for the inner heating oxygen sensors shall increase with temperature drop of exhaust gases; 试验表明,随着尾气温度的降低,采用内加热的氧传感器的内电阻、由浓至稀响应时间、浓混合比响应电压随之上升;
