SCAN-LAN 80 CABLE SCANNER
(Twisted Pair)
(Coax)
Any anomalies found will be flashed on the display.
Anomalies are reflections from impedance
mismatches located between the Scan-LAN 80 and
the end of the cable. They can be caused by a faulty
punchdown-block connection (twisted-pair
networks) or badly crimped cables (coax networks).
