Overview Chapter 1
1.1 Product Overview
The Hioki 3665-20 LAN CABLE HiTESTER is a hand-held cable
tester that provides easy operations to test wiremap, measure
cable length and identify twisted-pair cables. It is useful for verifying connections after installing connectors on cables. Optional
terminators are available to facilitate easy identification of multiple cables. The HiTester is especially convenient for testing
cables in working networks in the event of faults caused by
open- or short-circuited cable wiring.

Troubleshoot cables in working networks
When an open- or short-circuit fault is present in a cable, the
HiTester displays the distance along the cable from it to the fault.
So when a problem occurs in a working network, the HiTester
determines whether the problem is caused by an open- or shortcircuit in the cable, and its location (p.28).
Identifying cables installed together
When multiple cables are installed together, distinguishing which
cable is connected to what device can be difficult. However, the
HiTester can easily identify multiple cables by using optional terminators. Up to 21 cables can be identified using multiple terminators (p.29).

2.1 Installing the Batteries
Before using the HiTester, install two AA-size (LR6) alkaline batteries. Also, before each test, verify that the batteries have sufficient remaining capacity, and replace them if they are weak.
• Do not mix old and new batteries, or different types of batteries. Also, be careful to
observe battery polarity during installation.
Otherwise, poor performance or damage
from battery leakage could result.
• To avoid the possibility of explosion, do not
short circuit, disassemble or incinerate batteries.
• Handle and dispose of batteries in accordance with local regulations.
• The indicator flashes when battery voltage
becomes low. Replace the new batteries soon.
• Do not attempt to use any power source other
than the specified AA-size (LR6) alkaline batter
ies. Operating time with non-alkaline (manganese) batteries is shorter.

3.1 Basic Procedure
Cable Testing
Procedures Chapter 3
1
3.1 Basic Procedure
• To avoid equipment damage, do not attempt to
test a cable connected to an operating network.
The RJ-45 cable test jacks on the HiTester and
terminators are intended for testing only standalone cables.
• Do not connect any cable other than the twisted
pair cable. For example,
mately 48 V is applied to a live telephone wire,
and therefore will damage the HiTester if it is
connected to the wire.
• Remove a cable to be checked from any device
or a network hub before connecting the cable to
the instrument. Inserting the cable left connected with a device or hub into the instrument
can cause damage to the instrument and
device.
The characteristics of twisted-pair cables can vary
depending on installation conditions. Avoid unnec
essary bending of cables to be tested. When necessary to bend a cable, the radius of curvature
should be at least four times the outer diameter of
the cable.

The length of each wire pair may be displayed as
a different value depending on the cable type,
twisted pair condition or measurement accuracy.
The wire length of a split pair may be displayed
as shorter than its actual length (when an imped
ance mismatch exists).
• The HiTester measures cable lengths from 2 to
300 meters (6.6 to 984 feet). Cable lengths out
side of this range are not displayed.

4.1 Setting an NVP Value
Setting Procedure Chapter 4
4.1 Setting an NVP Value
NVP is the speed of a signal through a cable relative to the
speed of light in a vacuum. See "Section Theory of Cable
Length Measurement" (p.34) for details.
The optimum NVP value setting depends on the type of cable
and twist state of the wire pairs. Cable length measurement
accuracy can be optimized by setting the appropriate value for
the actual type of cable to be measured. The default HiTester
setting is 0.684.

SET
SET
4.1.1 Settings for Standard Cable
The most accurate cable length measurements are achieved by
setting the NVP value to match the actual type of cable to be
tested. Before measuring, prepare a standard reference cable
using a known length of exactly the same type as that to be
tested. Calibrate the HiTester according to the following procedure.
We recommend that the standard reference cable
be at least 100 m (382 feet) long.
A shorter length may result in larger measurement
errors due to the inaccurate NVP value obtained.
Prepare a standard reference cable and measure its
1.
actual (physical) length.
(This example shows a 100 m standard reference cable.)
Connect the HiTester to the standard reference cable.

Theory of Cable Length Measurement
The HiTester employs the TDR (time domain reflectometry)
method to measure the amount of time from the input of a pulse
to the return of its reflected wave from the far end of the cable.
Length is calculated by the following formula:
L : Cable length (m)
C : Speed of light in a vacuum = 3
T : Pulse propagation time from insertion to reflection return (s)
NVP : Nominal Velocity of Propagation (the speed of a signal through a
cable relative to the speed of light in a vacuum.)

(m/s)
Measurement Accuracy
Cable length measurement accuracy is ± 4% rdg. ± m, where
is the quantization error calculated as follows:

NVP : Nominal Velocity of Propagation
(Signal propagation speed as a percentage of the speed of light in

The following options are available for the 3665-20 LAN CABLE
HiTESTER. Ask your dealer or Hioki representative when ordering.
Terminators
To conveniently identify multiple cables with the HiTester, you
can use the optional terminators (sold in 5-piece sets) to eliminate the need to change cable connections at the far end.
• Model 9690-01 TERMINATOR (ID number: 1 to 5)
• Model 9690-02 TERMINATOR (ID number: 6 to 10)
• Model 9690-03 TERMINATOR (ID number: 11 to 15)

Maintenance
and Service
7.1 Cleaning
Chapter 7
1
Never modify the instrument. Only Hioki service
engineers should disassemble or repair the instru
ment. Failure to observe these precautions may
result in fire, electric shock, or injury.
7.1 Cleaning
To clean the instrument, wipe it gently with a soft cloth moistened with water or mild detergent. Never use solvents such as
benzene, alcohol, acetone, ether, ketones, thinners or gasoline,
as they can deform and discolor the case.
Wipe the LCD gently with a soft, dry cloth.
7.2 Troubleshooting
If damage is suspected, check the "Troubleshooting" section
before contacting your dealer or Hioki representative.
When sending the instrument for repair, remove
the batteries and pack carefully to prevent damage
in transit. Include cushioning material so the instru
ment cannot move within the package. Be sure to
include details of the problem. Hioki cannot be
responsible for damage that occurs during ship
ment.

Troubleshooting
Symptom Checks and Remedy
Cable length is not displayed
Is the cable between 2 and 300 m
long?
The cable length measurement
range of this instrument is 2 to
300 m (6.6 to 984-ft.). However,
cable length cannot be mea
sured if the cable’s characteristic
impedance is far from 100 .
The Model 9628 LAN CABLE is
1 m long, so it cannot be measured.
-
The results of the cable
length test is different from
the actual cable length.
Open or other incorrect wiring (? display) is displayed
even when a normal cable
is measured.
"No Terminator" is displayed
No ID number is displayed Are pins 1, 2, 3 and 6 connected
The amount of error specified for
cable length testing is ± 4%rdg. ±
1m. Please check first to see if the
test results come within this range.
If the test results are indeed out-
side of the accuracy range,
change the settings for the NVP
value.
(p.31)
Have you ever connected to a live
telephone wire, etc.? (p.17)
The HiTester may be damaged
due to an application of overvolt
age. Please send it for repair.

7.4 Replacing the Batteries
7.4 Replacing the Batteries
Replace batteries if they are weak.
• Do not mix old and new batteries, or different types of batteries. Also, be careful to
observe battery polarity during installation.
Otherwise, poor performance or damage
from battery leakage could result.
• To avoid the possibility of explosion, do not
short circuit, disassemble or incinerate batteries.
• Handle and dispose of batteries in accordance with local regulations.
To avoid electric shock, turn off the power and dis-
connect the testing cable before replacing the bat-
teries. After replacing the batteries, replace the
cover before using the instrument.
• The indicator flashes when battery voltage
becomes low. Replace the new batteries soon.

• Do not attempt to use any power source other
than the specified AA-size (LR6) alkaline batteries. Operating time with non-alkaline (manganese) batteries is shorter.
