Operation

Do not connect with DC voltage over 60V or any AC voltage live circuit equipment or it will result damage.

• Press “ ”key to power on, as show blow. Press key to choose function. Press“ ”key to test. Press“ ”key to return.

Note: The arrow “▲” on the LCD display indicates the test port location of the network cable to be tested.

• Graph 1: The cable shall be inserted into the middle RJ45 connector.
• Graph 2: The cable shall be inserted into the left RJ45(with LED) connector .

Cable map test：

• 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.
• Select the “CONT” menu and press “ ” to test with test results shown below:
• Telephone cable test results shown below:
• BNC coax test results shown below:
• 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.

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.

• Insert the pending network cable into the transmitter socket in the left. Do not plug in any socket at the other end.
• Select the “Length” menu and press “ ” to test with test results shown below:
• Units of length can select “Meter” “Yard” “Foot” under the Units menu.
• 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.
• 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 displayed as 0 meter.

Cables tracking：

• Connect one end of the target cable to the RJ45 socket in the middle of the transmitter, BNC coax into BNC socket.
• Select the “SCAN” menu and press “ ” to transmit and shown below:
• The receiver function switch is switched on to the “Scan” or “lighting” position.
• The receiver sensitivity knob is rotated clockwise to the maximum (the arrow tail is above).
• 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.
• 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.

Port Flash & Switch details testing:
This function transmits the pulsing signal through the transmitter to flash 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 in damage.
• Insert the network cable into the transmitter socket in the left.
• Select the “Flash” menu and press “ ” to start testing.
• The 2 indicators on the RJ45 jack port will be lit and flash. Then observe the ports on the 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.
• 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.
• 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.

Setting:
This function can set the language (Chinese / English), backlight time, automatic shutdown time, contrast, etc.

• Select the “Setting” menu and press “ ” to start setting.
• Backlight setting: Adjust the backlight time among 5S, 10S, 15S, on and off.
• Auto-off time setting: Adjust the Auto-off time among 15mins, 30mins, 1hour, off.
• Contrast setting: Press the “ ” to setting. And press key to adjust the contrast to suit yourself.
• Version information: To check version information of software and hardware. as above.

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).

• 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 a different frequency, the speaker rapid sound indicates a high voltage or fire line, the slow sound may be low voltage or zero line.

Note:

• This function is for reference, the voltage may still remain even if there is no detection. There are many possible factors that might block the detection.
• There are external sources (like flashlight and motor) may trigger non-contact voltage detection.

Flashlight

• Push the receiver switch to the “ ” position, and the front LED auxiliary lighting LED is turned on for lighting with insufficient light.
• Only for lighting in the case of insufficient light, do not use it for a long time to save the battery.

Battery Replacement

• 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.
• The battery is 6F22 or 6LR61 9V battery, and the better performance 6LR61 alkaline battery is recommended.
• Turn off the Transmitter or Receiver and disconnect all test leads before replacing the battery.
• Properly install in the case to power the Transmitter and Receiver.
