多功能电路检测器可用于检测汽车、摩托车及其它电路系统的线路通断、电压参数、高压打火等。它还可以检测元器件极性、判断质量优劣,同时还具有电子时间显示、定时闹钟、手电筒照明等多种功能及用途。 该检测器的原理方框图如图所示。它主要由音频振荡电路、感应检测电路、电压检测电路及时钟定时电路等几部分组成。 该检测器对高压线及高压打火进行感应检测时,高压信号被检测端感应到后,使感应检测电路中场效应管等元件组 Multi-function circuit detector can be used to detect the car, motorcycle and other circuit system on-off, voltage parameters, high pressure ignition. It can also detect the polarity of components to determine the quality of pros and cons, but also has electronic time display, time alarm, flashlight lighting and other functions and uses. The principle of the detector block diagram shown. It is mainly composed of audio oscillation circuit, sensing detection circuit, voltage detection circuit and clock timing circuit and other parts. When the detector detects the high voltage line and the high voltage ignition, the high voltage signal is sensed by the detection terminal, and the sensor group such as the field effect transistor in the detection circuit
