Working principle of the present invention is as follows: the both ends of tested conducting wire will be needed to be inserted into two sockets of A, B respectively first
On, trigger signal, that is, 15V voltage is introduced by 1A interface by first switch, if first conducting wire of winding displacement can be normal
It is connected to 1B from 1A, then the voltage at 1B is 15V at this time, i.e. 3 feet of the first operational amplifier meet 15V, and 2 feet connect 5V, the output of 1 foot
High level 15V lights the first light emitting diode, while the high level of 15V is transmitted to 2B interface；If second conducting wire of winding displacement
It normally can be connected to 2A from 2B, then the voltage at 2A is 15V at this time, i.e. 5 feet of second operational amplifier meet 15V, and 6 feet connect
5V, 7 feet export high level 15V, light the second light emitting diode, while the high level of 15V is transmitted to 3A interface；Class according to this
