  • Page 12: Locating And Isolating Cables

    OPERATION 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, STP, Cat 5e, Cat 6) and telephone line (Cat 3). Use with a patch cord for RJ45 / RJ11.
  • Page 13 Locating Individual Wire Pairs with the MT-7028 Analog Function To locate cables, do the following steps (Figure 3)： Connect the black alligator clip of the Transmitter to the ground, and then connect the red clip to a jack or punch-down block as shown in Figure 3.

  • Page 14: Isolating Cables

    Repeat the steps of 6 and 7 to isolate the bundled cables. Caution • If you cannot locate the MT-7028 signal on 2-conductor cables, the cable may be shorted or opened. Use the Continuity Test (Fig. 8) to check for shorts or opens on coax and non-terminated cables.

  • Page 15: Cable Map Testing

    RJ45/RJ11 compatible connector on transmitter. Do not use RJ11 (6pin) connector. • You can use the MT-7028 Transmitter or Receiver to validate the cable map on RJ45/RJ11 by RJ45/RJ11compatible connector on transmitter. The cable map function finds the most common wiring faults on twisted pair cabling: shorts, opens, and crossed pairs.
  • Page 16 Transmitter cable map, 6P/6C each second from 2 to 7 in sequence, 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.
  • Page 17 Transmitter MT-7028 Figure 6 Different Connector’s Cable Map You can use the MT-7028 Transmitter and Receiver to validate the cable map on RJ11 and RJ45 connectors. The cable map function finds the most common wiring status on twisted pair cabling: good, shorts, opens, and crossed pairs as shown in Figure 7.

  • Page 19: Live Telecommunication Equipment And Router Test

    TEST green LED light will be off and the product will be standby for next operation. When the “1~8, G” LED indicator on MT-7028 transmitter lighted one by one, the cable (1~8, G) is good. If any of LED indicator is not lighted, the cable is damaged.

  • Page 20: Coaxial Cable & Continuity Testing

    Coaxial Cable & Continuity Testing: DANGER ： Before testing, please be sure the power of receiver is OFF. To validate cable shield during cable map tests, do the following as shown in Figure 9: Connect the Transmitter to the circuit as shown in Figure 8.

  • Page 21: Validating Telephone Service And Polarity

    Validating Telephone Service and Polarity： Please follow the following steps to check the polarity of telephone lines: Connect the Transmitter to the circuit as shown in Figure 9. Connect the test leads to the telephone punch-down blocks, RJ11, and RJ45 jacks. Push button to turn on the power, “POWER/ BAT LOW”...

  • Page 22: Ncv (Non-Contact Voltage) Testing

    Per Figure 11, turn the switch to “NCV”, the function is started when the power indication is on. When doing the NCV testing, place the probe of MT-7028 receiver to the tested cable, the NCV indicator twinkled fast and the buzzer sounded it means the tested objective has AC 90~1000V.

  • Page 23: Battery Life And Replacement

    Battery Life and Replacement Caution To avoid unreliable test results, replace the battery as soon as the low battery indication appears. Warning To avoid possible electric shock or personal injury, turn off the Transmitter or Receiver and disconnect all test leads before replacing the battery.
