4 Way Coaxial Cable Mapper The 4 way coaxial cable mapper is designed to find and identify multiple coax cables. It is a hand-held device for CATV and security system installers who test multi-run coax systems terminated with F-connectors, or those who wish to map runs to a central bundle. It can be used to put a tone signal on a coax cable. With four individual remote terminators, it’s ideal for mapping coax installations. Maps: Up to 4 cables Brand: Revez Colour: White Model: CM4 Made in Taiwan Specifications: ♦ Test for Opens and Shorts ♦ Bright Red and Green LEDs display the test results ♦ Identifies 4 individual Remotes by measuring their precision resistance ♦ Auto Power Off: 12 seconds after Pass/Fail results, 30 minutes in “Tone” mode ♦ Maximum cable length for testing: 4000 Ft (1,200m approx) ♦ Maximum DC cable resistance: 100 Ohms ♦ Battery: A 9V Battery ♦ Included 4 serial-number terminators. Note: The CM4 will not test cable runs with AC or DC voltage present. Additionally it will not test through Amplifiers, DC blocking devices or isolation splitters.
