Question: What are the test methods for the cable identifier? Answer: Setup Test Loop Connect the red output jack to the core of the cable to be identified, connect the black output jack to ground, and connect the cable core to ground at the far end. The problem of output current in the cable: what are the test methods of the cable identification instrument? Answer: Set up the test loop Connect the red output jack to the core wire of the cable to be identified, connect the black output jack to the ground, and connect the cable core wire to the ground at the far end. The output current flows to the far end in the direction of the arrow in the cable, and returns to the generator through the ground to connect all the core wires of the identified cable together, and a clearer signal can be obtained.
2. When calibrating and calibrating the receiver, use the sensor to clamp the cable at the beginning (close to the generator), the arrow points to the current direction, that is, to the far end of the cable, and then use the same receiving sensitivity for detection at the place to be detected, use the sensor Snap each cable once, the arrow direction points to the far end of the cable, when the cable that needs to be identified is stuck, the receiver meter will display a reading of 4-6, and it will swing to the right.
