Failures Detected
Shorts
Range of short detection: 0 m to 350 m (1 ft to 999 ft)
Accuracy of distance to a short (Assumes short is 0 Ω):
UTP/FTP/STP: 7 % + 3 m (7 % + 10 ft)
Coaxial Cables 10 % + 10 m (10 % + 30 ft)
Resolution of distance to a short:
UTP/FTP/STP: 0.5 m (1 ft)
Coaxial Cables: 1 m (5 ft)
Opens
Range of open detection: 0 m to 350 m ( 0 ft to 99 ft)
Accuracy of distance to an open:
UTP/FTP/FTP: 10 % + 1 m (10 % + 3 ft)
Resolution of distance to an open:
Cables < 100 meters: 0.5 m (1 ft)
Cables > 100 meters: 1 m (3 ft)
Split Pairs
Range of detection: 2 m to 350 m (6 ft to 999 ft)
Split pair part of the cable must be at least 2 meters (6 ft)
in length and greater than 10 % of the total cable length.
Coax Termination Measurements
Any loop resistance value between 5 ohms and 350
ohms is interpreted as a termination resistance.
Resistance values below 5 ohms are considered shorts
and resistance values greater than 350 ohms are not
displayed.
LAN Input Connectors
RJ45, DB-9, and BNC
Input Protection
56 V dc continuously through a balanced source
impedance of 400 Ω. 175 V peak, 20 Hz to 60 Hz through
100 Ω, superimposed on 56 V dc through 400 Ω.
“ACTIVE CABLE” is displayed and an audible signal
sounds when the test tool is connected to a cable with
voltage present.
The test too is not intended to be connected to a public
telephone network.
