Product parameters: Test
wire: Test
RJ45/RJ11/UTP/STP testing method: 1. Press the power switch, if the red light flashes, it means the power is normal. 2. Insert both ends of the twisted pair into the main tester and the remote terminal to start scanning one by one. If the wire is good, the corresponding indicator lights will show green in order; if the light is red or not lit or out of order after showing green first, then the twisted pair is bad. 3. Press the GND switch to test. If the 3*6 lights are off, and the other lights and GND lights show green, the shielding is normal. If any one of the lights turns red or does not light up after showing green, the shield is broken.
