Coax cables are one of the leading materials employed for networking a home or office. Either it is for satellite, cable or internet, coax cable has a potential application in most rooms of a home or business. Like with many other networking cables, a coax mapper is a product oftentimes used to debug a network of cables in a home or office. The coax tester is a handheld instrument designed to put a tone signal on a coax cable to find and identify a amount of cables that may be located in a structured media panel or enclosure. Coax mappers typically come with four to eight uniquely colored F-terminators. Some models like the Test-Um Cx200 also include Bnc connectors because these are tasteless in Cctv applications.
In this section, we'll tell you how the coax mapper operates. For most models, press and hold the Test button and release when ready to test the cable. Results are displayed for some seconds before shutting off automatically. An Led will Light for the color of the terminator found. If there are splitters related in the path, an Led will Light for each terminator. Before going straight through these steps, achieve a quick estimate to settle if any voltage is on the coax cable. A positive Dc or Ac voltage on the cable would trigger the 'voltage' Led of the coax mapper to Light. If this happens, disconnect the coax tester from the line and take off the voltage generating source from the coax cable arrangement. Coax testers will not typically test cable with Powered amplifiers, isolation splitters, attenuators, directional taps, Power dividers or transformers.
Cable Tester
As mentioned earlier, coax testers are Battery operated. Most models like the benefit Meters Adv1018 and Adv1008 are sold with 3V Batteries included. Consider reChargeable Batteries if you are a expert installer that uses the coax tester oftentimes and your model offers that option. If the Batteries aren't reChargeable, you will just need to keep a Watchful eye on their Charge.
