Both straight-through and crossover cables (10/100BASE,
1000BASE-T and 1000BASE-TX) can be checked.
PASS Display Examples
Detect the existence of
shields or check for shield integrity.
Fully Compatible to
CAT6 LAN Cables
FAIL Display Examples
Pins 1 and 2 are reversed. Pins 3 and 6 have been
incorrectly paired with Pins
4 and 5.
Pin 1 is open at a distance 7
meters from the LAN cable
tester.
Pins 1 and 2 are shorted at a
distance 10 meters from the LAN
cable tester.
A very common mistake - twist
pairs Pins 3+6, and Pins 4+5,
have been incorrectly connected.
For wiring confirmation and locating broken wires after installation.Quick PASS/FAIL reading helps you complete your work faster.

Have you ever had trouble
installing additional cables?
Take advantage of the conveniences offered by the
tester's capabilities to check wiring while confirming
multiple cable destinations.
Up to 21 terminators can be connected (additional terminators
sold separately.) Convenient for confirming the connection
destinations of multiple cables.
You will never need to go back and forth
again just to change the terminators.

■ Activating the NVP function is as simple as 1-2-3
NVP (Nominal Velocity of Propagation) is the ratio of the speed of a signal in the cable relative to the speed of light in a vacuum.
NVP differs according to the type of cable and the manner in which the wire pairs are twisted, so measurement accuracy can be enhanced by setting the NVP value for the particular type of cable to be measured.
Preparation
The HIOKI 3665-20 can do the job for you properly and
accurately by also detecting split pairs.
To properly check LAN cable wiring,
a tester capable of detecting split pairs is indispensable.
For wiring confirmation and locating broken wires after installation.Quick PASS/FAIL reading helps you complete your work faster.
Measure for cable length and detect the location of broken or short-circuited wires.

Direction
The NVP setting is a cable-length compensation function that enhances the
accuracy of cable length measurements.
Accuracy with NVP activated:
■ ± 4% rdg. ± 1m
(vs.previous HIOKI model: 15% rdg. ±1m)
Increased
Precision!
Split pairs appear to be properly
connected to the untrained eye,
and cannot be detected with continuity
testing. OK!
How Can Split Pairs Affect the Network?
◆ Communication speed can be suppressed - 100BASE signals may reach only 10BASE speeds.
◆ Excessive communication errors - data transfer may be intermittent or completely inhibited.
◆ Cables miswired in this way are more susceptible to electrical noise.
Increased
Effi ciency!

Finished
On the Settings screen,
select “Length Adjust”.
Press the TEST button to
measure the (already known)
length of the reference cable.
Calibrate the display to the
measured reference cable.
Prepare a reference cable using a
known length of the same type as that
to be measured (at least 100-meter
length recommended).
