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

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.

Cable Length

Locate up to 21 unique cable destinations.

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!

Setting

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).
