This product can perform the network wire length testing. This

product is suitable for telecommunications, network communication,

monitoring, CATV and other indoor and outdoor wiring construction

or maintenance projects.

Caution

!This product uses 9V 6LR61 or 6F22 battery power supply, and

6LR61 battery is recommended.

!To save the battery, please shut down immediately after use. If it

is not in use for a long time, please remove the battery in the

transmitter and receiver to avoid damage to the product caused by

battery liquid from leaking out.

!This product is strictly prohibited to access the live lines above

3.1 Cable map test：

Ø Insert the pending network cable into the transmitter RJ45 socket in

the middle and the other end into the receiver socket or remote unit,

BNC coax into BNC socket.

Ø Select the “CONT” menu and press “ ” to test with test results

Ø BNC coax test results shown below:

Ø If the display "cable open " indicates that the network jumper is all

open or the other end of the network cable is not inserted in the test

remote or receiver, or the test interface is wrong.

3.2 Measure Cable Length：

During the test, the power consumption is large and the

battery power decline is fast. the test time should be interval

until the battery power is restored.

Ø Insert the pending network cable into the transmitter socket in the

left. Do not plug in any socket at the other end.

Ø Select the “Length” menu and press “ ” to test with test results

shown below:

▲

CONT

Ø Units of length can select “Meter” “Yard” “Foot” under the Units

menu.

Ø Because each pair of wire has different twisted density, it is normal

to measure the numbers slightly different, which can be measured

many times to get the same measurement value.

Ø From the image, it means there exists problem at 12.1m. To make

sure it is short or broke there, you can test it continuity to know

details.

■ NOTE: Kind reminds when measuring cable length.

1. The network cable to be tested must be de-energized.

2. Disconnect the cable at the far end, no remote, no other

devices connected!

3. The range must be 2.5m—200m, otherwise , it would be

display 0 meter.

3.3 Cables tracking：

Ø Connect one end of the target cable to the RJ45 socket in the

middle of the transmitter, BNC coax into BNC socket.

Ø Select the “SCAN” menu and press “ ” to transmit and shown

below:

Ø The receiver function switch is switched on to the "Scan" or

"lighting" position.

Ø The receiver sensitivity knob is rotated clockwise to the maximum

(the arrow tail is above).

Ø Press and hold the "SCAN" button in the middle of the receiver,

while the probe is close to the network cable to be measured, the

speaker emits a clear "beep-beep " sound, and the network cable

contacted by the receiver probe is the target network cable to find.

Ø When tracking a cable in the working network, due to the network

switch, there may be audio signals adjacent to the target cable,

each cable can be removed to find the target cable or try to rotate

the receiver sensitivity knob counterclockwise to reduce the

reception sensitivity to find the target cable.

3.4 Port Flash & Switch details testing:

This function transmits the pulsing signal through the transmitter to

flashing the LED indicator of the network switch, then can locate the

interface of the network cable on the switch. At the same time, the

network switch working performance can be tested.

Do not connect with DC voltage over 60V or any AC

voltage live circuit equipment or it will result damage.

Ø Insert the network cable into the transmitter socket in the left.

Ø Select the “Flash” menu and press “ ” to start testing.

Ø The 2 indicators on the RJ45 jack port will be lit and flash. Then

observe the ports on switch, if there is a port whose flash frequency

is 3 secs, and slower than all the other ports, it tells you the port is

target one you’re looking for.

Ø Also, the device can tell you the connected switch’s information,

such as its speed (10M/100M/1000M), transmitting modes (FDX:

full duplex/ HDX: half duplex) Protocol (Auto- Nego / Non-Auto-

Nego). See the graph for ref. as below.

Ø If "Check Port" is displayed, the reasons may be: 1. Network cable

insertion error and test interface; 2. Network cable is not connected

to the switch; 3. Network cable fault. 4. Switch, router fault or

incompatibility with the instrument. 5. This instrument fails.

3.5 Setting:

This function can set the language (Chinese / English), backlight time,

automatic shutdown time, contrast, etc.

Ø Select the “Setting” menu and press “ ” to start setting.

Ø Backlight setting:

Adjust the backlight time among 5S, 10S, 15S, on and off.

3.6 Non-contact Voltage detection (NCV)

This function is used to determine whether the wire or equipment has

an AC voltage, the detection range AC90-1000V (50 / 60Hz).

Ø Push the receiver function switch to the NCV position, put the

receiver probe close to the target body, if the AC voltage is

detected, the speaker emits an alarm sound of different frequency,

the speaker rapid sound indicates a high voltage or fire line, the

slow sound may be low voltage or zero line.

./0

Note:

l This function is for reference, the voltage may still remain even

there is no detection showed up. There are many possible

factors might block the detection.

l There are external sources (like flashlight and motor) may trigger

non-contact voltage detection.

3.7 Flashlight

Ø Push the receiver switch to the “ ” position, and the front LED

auxiliary lighting LED is turned on for lighting with insufficient light.

Ø Only for lighting in the case of insufficient light, do not use it for a

long time to save the battery.

4. Battery Replacement

Ø When the battery symbol on the transmitter display is low, replace

the battery. When the receiver power indicator flashes, the battery

is low, replace the battery.

Ø The battery is 6F22 or 6LR61 9V battery, and the better

performance 6LR61 alkaline battery is recommended.

Ø Turn off the Transmitter or Receiver and disconnect all test

leads before replacing the battery.

Ø Properly install in the case to power the Transmitter and

Receiver.
