620 CableMeter
Introduction
The Fluke 620 LAN CableMeter (hereafter the test tool)
is a battery operated, handheld instrument that identifies
cable failures, measures length, and checks the wiring of
cables used for DeviceNet, ControlNet, and Ethernet
Local Area Network (LAN) systems.
The test tool is designed around a “Test as You Go”
philosophy. This reduces the time necessary to install and
service LAN cables by allowing ONE PERSON to detect
most cable failures from only one end of the cable.
The test tool tests for incorrect pairing (split pairs),
miswires, shorted and open wires on all twisted pair
cables, as well as shorts on coaxial cables.
The test tool comes with the following:
1 620 Softcase
1 RJ45-RJ45 Straight-Through Patch Cable (EIA/TIA
4 Pair Cat5)
1 RJ45-RJ45 Female Coupler
1 User Manual
1 Cable Identifier #1
1 Quick Reference Card
1 Warranty Registration Card
Caution
To reduce wear on the test tool connector,
leave the patch cable connected to the test
tool and use the patch cable to connect to the
cable under test.
Plugging a 4 or 6 position plug into the test
tool’s UTP/FTP jack can cause permanent
damage to the jack pins.

Safety Information
The international electrical symbols used on the
instrument or in this manual are described in Table 1.
Table 1. International Electrical Symbols
Warning or Caution: Risk of damage or destruction
to equipment or software. See explanations in the
manual.
Equipment is protected by double insulation or
reinforced insulation to protect the user against
electric shock.
Do not connect this terminal to public
communications networks, such as telephone
systems.
Conforms to relevant European Union Directives.
Warning
To avoid possible fire, electric shock,
personal injury, or damage to the test tool.
• To avoid false test results, replace the
batteries as soon as “LOW BATTERY”
appears in the display.
• Never connect the test tool to any
telephony inputs, systems, or equipment,
including ISDN. Doing so is a
misapplication of this product, which can
result in damage to the instrument and
create a potential shock hazard to the
user.
• Never connect the test tool to active LAN
inputs, systems, or equipment. Doing so
is a misapplication of this product, which
can result in damage to the instrument
and create a potential shock hazard to the
user.
• Always turn on the test tool before
connecting it to a cable. Turning the test
tool on activates the tool’s input
protection circuitry.
• When servicing the test tool, use only
specified replacement parts.
• Do not use the test tool if it is damaged.
Protection may be impaired.
• Do not use the test tool if it is damaged.
Inspect the test tool before use.
