Portable 2M wire detection device

The invention discloses a portable 2M wire detection device, which comprises a detection mechanism and a feedback mechanism; a 2M wire sending terminal sends an analog voltage signal through a microcontroller, a receiving terminal is used for receiving and judging the analog signal, a receiving state is displayed through a mini touch screen, and the detection device is mainly controlled through amicrocontroller. Compared with a traditional 2M wire detection device, the 2M wire detection device is updated in the aspects of transmitting terminal design, receiving terminal design and intelligentdisplay, and the test signal transmitting terminal and the test signal receiving terminal of the 2M wire detection device are integrated on one test instrument. During specific use, the 2M wire testinstrument sends an analog signal to one end of the 2M wire through the test signal transmitting terminal, then analyzes the problems of the 2M wire through a signal fed back by the receiving signal receiving terminal connected
