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.

Preparing the Test Tool for Use
Audible Signal (Beeper)
The test tool uses an audible tone to signal different
operational conditions. A single short tone indicates a
pass condition withough a Cable ID detected. A two
frequency tone signals a pass condition with a Cable ID
detected. Three short tones signal a test failure. A long
tone sounds whenever an invalid key is pressed. A
continuous, varying-pitch tone signals the test tool is
connected to an active cable and should be disconnected
immediately. To disable the audible signal for the PASS
and FAIL conditions, see “Setup Selection".
Low Battery Indication
When the battery voltage is low bit it is OK to continue,
the test tool displays “LOW BATTERY” once during a
power-on session. When this message first appears there
will be about 8 hours of use left. When the battery voltage
is too low to continue, the unit displays “REPLACE
BATTERY”. To continue using the test tool, you must
replace the batteries. Refer to “Replacing Batteries” .
Battery Save Mode
The test tool turns itself off when there is no switch or key
activity for 10 minutes. To return the test tool to operation,
you must turn the rotary switch to OFF and wait 5
seconds before turning the test tool back on. The Battery
Save feature may be disabled by turning the rotary switch
to OFF, then pressing and holding E while turning the
rotary switch to TEST.
Cable ID Unit
The Cable ID Unit permits the detection of far end wiring
failures and helps identify cables between a room and a
wiring closet. For use with twisted pair cable only.

Preparing the Test Tool for Use
Note
Cables not wired according to the predefined
cable list cause the test tool to detect failures.
However, the test tool will determine the cable’s
length and display the actual cable wiring with
the wire map function. It may be possible to use
the test function by making an adapter that
causes the cable to appear to be properly wired
to the test tool.
To set up the test tool for the desired cable, perform the
following:
Note
The number of steps necessary to select a cable
definition will depend on the type of cable selected.
1. Turn the test tool on by selecting TEST, LENGTH, or
WIRE MAP.
2. Press A.
3. Press C or D until the desired cable type is
displayed, then press E.
4. Press Cor D until the desired wiring standard is
displayed, then press E.
5. Press C or Duntil the desired category is
displayed, then press E.
6. Press C or D until the desired wire size is
displayed.
Note
You can check the cable selection at any time
other than during the setup mode by pressing
the
E
key.
The cable characteristics are now defined by the factory
settings for the cable selected. However, cables coming
from different batches or manufacturers can have
characteristic variances of up to 20 %, causing deviations
in length measurements. To obtain more accurate
measurements, calibrate the test tool to the specific cable
under test.
Calibrating the Test Tool to the Cable
When calibrating the test tool to a specific cable, the
cable should be at least 100 feet (30 m) long and of the
same type and category as the cable under test.
Calibrating with cables longer than 100 feet (30 m) will
improve length measurement accuracy. During the
calibration process, if the cable is found to be defective or
if the cable is less than 50 feet (15 m), “BAD CABLE” is
displayed and the calibration process is terminated.

620
Users Manual
Caution
For proper calibration, connect the cable
under test directly to the test tool, not
through a patch cable.
abm04f.eps
Caution
To ensure accurate measurements, make
sure conductive objects, including fingers,
do not come in contact with any of the
connectors while the test tool is measuring
the cable under test.
To calibrate the test tool to the currently selected cable,
perform the following:
1. Connect a good cable of known length, 100 feet (30
m) or longer, to the appropriate test tool conenctor

parameters are stored and will remain in memory
even if the test tool is turned off. All future
measurements for this cable type are compared to
these new parameters until another cable is selected
or another calibration is performed.
Making Tests and Measurements
The test tool displays test results in relation to individual
pin numbers. For example, in the LENGTH mode, the
following display indicates the twisted pari connected to
pins 1 and 2 is 301 feet long whilc the pair connected to
pins 3 and 6 is 300 feet long.
abm06f.eps
When you are testing STP cabling, the pin number
displayed always corresponds to the pins at the STP (DB-

the display if a cable calibration has been performed
for the selected cable type. If the test tool is not set
up for the cable under test, refer to “Preparing the
Test Tool for Use”.
When you are testing twisted pair cables, the test tool
checks for a Cable ID Unit at the other end of the cable
and displays one of the following when a pass condition
exists:
Good cable, Cable ID#8

abm08f.eps
Note
The test tool may not sense the Cable ID Unit
under some open and short conditions. The test
tool will alternately display a ? and a number
when the Cable ID is detected but its number
can not be dertmined with certainty.

When testing coaxial cables with a termination, the test
tool displays the totatl resistance of the termination and
cable wires.
abm09f.eps
Coaxial cables must be unterminated for the test tool to
display the cable’s length. An open in a coaxial cable
looks just like an unterminated cable. A length
measurement that is less than the known cable length
would indicate a possible open in the cable.
The test tool sounds three short tones and displays FAIL
if a failure is detected. Additional information about the
failure is printed on the second line of the display and if
the ] symbol is displayed, additional information can be
viewed with the D C keys.
Note
The failure messages refer to individual wires
rather than pairs of wires.

CableMeter
Making Tests and Measurements
Measuring Cable Length
The test tool measures the length of both twisted-pair and
coaxial cables. If the test tool is not calibrated to the cable
under test, then factory default characteristics are sued to
compute hte length. If a more accurate length
measurement is desired, refer to “Calibrating the Test
Tool to the Cable”.
Before a length measurement is made, the test tool
performs diagnostic tests to prevent any cable failures
from corrupting the length measurement. All failures are
described in the “Testing Cables”.
To measure the length of a cable, do the following:
1. Connect the cable under test to the appropriate
connector on the test tool.
2. Turn the rotary switch to LENGTH.
3. This step can be omitted if you know the cable
selection is correct for the cable under test. Press
E to check the cable selection. The test tool
displays the cable selection for a few seconds and
then starts the test. “CAL” appears in the second line
of the display if a cable calibration has been
performed for the selected cable type. If the test tool
is not set up for the cable under test, refere to
“Preparing the Test Tool for Use" to select a new
cable setting.
Note
When the display flashes 999’ (350 m) during a
length measurement, the length of the cable
exceeds the tst tool’s range of measurement.
The information that is displayed depends on the type of
cable selected. For twisted pair cables, each pair has its
corresponding length measurement. A 5 percent
difference in length between pairs is not uncommon.
For EIA/TIA 4PR cable with no failures, the display shows
the following:
abm21f.eps
abm22f.eps

Users Manual
Length of a coaxial cable terminated in a resistance
cannot be determined by the test tool. Only the total
resistance of the wire and termination is displayed. An
unterminated coaxial cable 445 feet long will display the
following:
abm23f.eps
Checking the Wire Map
Using the test tool’s Wire Map function and a Cable ID
Unit, you can determine the wiring of both the near and
far end of the cable. To test the Wire Map, perform the
following:
1. Connect the cable under test to the appropriate
connector on the test tool.
2. Turn the rotary switch to WIRE MAP.
3. This step can be omitted if you know the cable
selection is correct for the cable under test. Press
E to check the cable selection. The test tool
displays the cable selection for a few seconds and
then starts the test. “CAL” appears in the second line
of the display if a cable calibration has been
performed for the selected cable type. If the test tool
is not set up for the cable under test, refere to
“Preparing the Test Tool for Use” to select a new
cable setting.
Note
If you select the COAX wire type while in the
WIRE MAP mode, the test tool will perform the
LENGTH function on the cable.
Assuming the cable attached to the test tool is a EIA/TIA
4 pair cable with no failures, the following display
indicates a good cable:
Near End
Far End
abm24f.eps
The top line always displays the near end of the cable;

Without a Cable ID Unit connected to the far end of the
cable, the test tool displays “—“ for the ID number.
The following display indicates the near end wiring of a
cable without a Cable ID Unit connected.

The IBM data connector contains self-shorting
connections between pins 5 and 6 (TX- and RX-) and 1
and 9 )RX+ and TX+) on the STP connector. Since this is
a normal connection for the IBM data connector, the tst
tool does not display a failure. In the wire map function,
the presence of these shorts are displayed as shown
below:

Maintenance
General
Periodically wipe the case with a damp cloth and
detergent; do not use abrasives or solvents. Clean and
dry as required. If the test tool will remain unused for an
extended period, remove the batteries to prevent damage
from leakage.
Replacing Batteries
Two 1.5 V AA alkaline batteries power the test tool and
typically provide 50 hours of operation. Using the
backlight may significantly reduce battery life. The battery
compartment is located at the bottom of the test tool. To
remove the battery cover, push the lip in and lift the cover
off (see Figure 5).
