OPERATION 1. Locating and Isolating Cables: Using MT-7028 Networking Tone & Probe kit to locate and insolate cables using the 1KHz analog, also trace twisted wires (UTP,Cat 5, Cat 5e, Cat 6) and telephone line. Use with a patch cord for RJ45 / RJ11. Coaxial cable, general cable and various wiring boards can be tested by using with alligator clip cable.

White noise from MT-7028 Receiver is normal when your Transmitter is near any of the interference. If you cannot locate the signal on 2-conductor cables, the cable may be shorted. Please keep away from the interference sources or turn off the electronic devices.

, the indicator of “POWER/ As the Figure 1 shown, when push BAT LOW” will light up and turn on the power. Push button for cable tracing. When the RED indicator flickers, the low-tone cable tracing is working. Push button again to feature the high-tone cable tracing, the RED indicator will flicker faster.

6P/4C each second from 3 to 6 in sequence, 6P/2C each second from 4 to 5 in sequence is synchronized with the MT-7028 Receiver cable map. If it encounters an empty line, the indication will cease. Figure 4 Different Connector’s Cable Map You can use the MT-7028 Transmitter and Receiver to validate the cable map on RJ11 and RJ45 connectors.

When doing the NCV testing, place the probe of MT-7028 receiver to the tested cable, the NCV indicator twinkles fast and the buzzer sounds, which means the tested object has AC 90~1000V. If there is no response of indicator and no buzzer sounds, it means the tested object has AC power less than 90V or there is no AC power on it.
