The test is finished by pressing the total test button again. And a tester can know whether the 16-core cable to be tested works normally or not by displaying the color of the lamp.
If a certain core wire or a plurality of core wires which are judged to be faulty in advance need to be tested, a sub-test button corresponding to the core wire is pressed, a low-level second trigger signal is generated after the sub-test button is pressed and is transmitted to a second pin of the processor, the processor responds to the second trigger signal and outputs a digital signal to the digital-to-analog converter, a pulse signal output by the digital-to-analog converter is transmitted to the core wire, if the core wire is normal, the receiving unit 103 receives the high-level pulse signal and outputs a normal feedback signal to the processing unit 104, and the processing unit 104 receives the normal feedback signal and lights a green display lamp corresponding to the core wire; if the core wire fails, at this time, the receiving unit 103 receives the low-level pulse signal and outputs an abnormal feedback signal to the processing unit 104, and the processing unit 104 receives the abnormal feedback signal and turns on the red display lamp corresponding to the core wire.
