When testing Coax type cables and RJ45 with the ends at different locations the included Remote Terminator is used to test for Open Short or Crossed connections. When an Open condition is detected the distance to the break point is displayed. The Remote Terminator is stored in the base of the unit and can be easily removed for testing.
Both the Length and Tone modes are tested without a terminator or direct connection to the other end of the cable. The length mode shows the total length of the cable or the length to any existing cable break. In Tone mode the tester sends a tone down the cable which can be sensed using an Amplifier Probe (not included). This can be used identify cables within a bundle or as an alternate method of locating cable breaks.
A built-in memory module allows you to store 8 results each for LAN and TEL modes plus 4 results each for Coax and Length modes. The tester has an automatic power-off feature to save battery life which kicks in after 5 minutes of nonuse in all modes except TONE mode and after 30 minutes in TONE mode.
