The Datamaster®Professional LAN Cable Tester is suitable for use with UTP (unshielded)
and STP (shielded) Cat-5, Cat-5E, Cat-6, Cat-6A and also with Coaxial cables. The Loopback
and Remote operating modes indicate cable continuity, wiring configuration (and type of fault)
and the type of cable being tested. TDR (Time Domain Reflectometer) technology is used to
measure cable lengths between a range of 1 to 350 metres. TDR is also used to indicate the
distance to a short or open circuit.
Auto-off mode (except in TONE MODE) prolongs battery life. A low-battery condition is
displayed when it is time to change the battery. The backlit LCD screen has four lines of 16
characters. A Tone mode is provided for F-Set probe fault location or identification. There are
24 memory locations for storing test results.
It is supplied with belt clip, black zippered vinyl pouch, 2 x F-type to BNC coax adaptors, 2 x 8P to
6P modular reducers and a 9V battery.
