With the digiwave dgtct01pro perfectional cable tester with multiple adapters users can detect dc continuity or shorts with a loud tone & led display. It can be used to identify and trace individual cables when multiple cables are present. The cable installer uses the digiwave dgtct01pro to place a dc current through one end of the desired cable and identifies the cable at the other end with the removable tone device. Simply unscrew the tone detector, attach the push-on fitting to the end of a coaxial cable, and touch the tone detector to each of the cables, when the correct cable from the transmitter location is found, the tone will sound.
