Description
The Greenlee 45057 Multi-Network Cable Tester is intended to verify
the continuity and pin configuration of various communication circuits.
It consists of a self-contained transmitter/receiver and a remote receiver.
The transmitter/receiver can be used alone to verify the integrity of a cable
prior to installation, or used with the remote receiver to test cable after
installation. The 45057 can be used to check Ethernet 10 Base-T, RJ-45,
RJ-11, Token Ring, USOC 4, USOC 6, USOC 8, EIA/TIA 568A, EIA/TIA
568B, AT&T 258A, BNC Coax Cable, and others.
The transmitter/receiver requires a single 9-volt battery; the receiver draws
its power from the transmitter and does not require a separate battery.
Features
Hazards or unsafe practices which, if not avoided, COULD result in
minor personal injury or property damage.
A person who has not read and does not understand
all operating instructions is not qualified to operate
this tool.
Failure to read and understand safety instructions
could result in injury or death.
