User Guide CT100 Network Cable Tester Introduction Congratulations on your purchase of the Extech CT100 Network Cable Tester System. The system consists of a Transmitter and a Receiver. This system automatically performs the following tests: Continuity, Open/Short Circuits, and Wire Crosses (Reversals). The CT100 tests “F” type coaxial and RJ45 terminated cables meeting the following wiring standards: • 10Base-T • AT&T258A • EIA/TIA 568B • Token Ring Operation WARNING: Do NOT test on LIVE CIRCUITS 1. Power the transmitter by moving the ON/OFF switch to the ON position. The power LED will light. 2. To test a patch cable, connect one end of the cable under test to the Transmitter and the other end to the Receiver. Testing begins automatically and is indicated by the stepping action of the LEDs on the Receiver. (Note: To test cabling that is part of an installation, the Transmitter and Receiver must be connected in line with the installation. Patch-cords needed to connect from wall-plates to the Transmitter and Receiver must be provided by the user.) 3.
