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.
Read and understand this material before
operating or servicing this test instrument.
Failure to understand how to safely operate
the test instrument could result in an
accident causing serious injury or death.
