• QC : It is used to detect the network cable plug and network cable crimping is “through” or “fail”.

CONT

• Insert the pending network cable into the transmitter (QC/CONT) RJ45 socket in the right and the other end into the receiver socket.
• Select the “CONT” menu and press “Enter” to test with 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 receiver, or the test interface is wrong.

Measure Cable Length
Cable length measurement range:2.5m~200m; Applicable to CAT.5(CAT5e) and CAT. 6 network cable.

• Insert the pending network cable into the transmitter “Flash/PoE /Length” RJ45 socket at the head of the transmitter. Do not plug in any socket at the other end.
• Select the “Length” menu and press “Enter”, and access the menu below, Select the network cable type CAT 5 or CAT 6 in the Type menu.
• Units of length can select “Meter” “Yard” “Foot” under the Units menu.
• Select the “Start Test” menu and press “Enter” to test with test results shown below:
• 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. Only one end of the network cable is inserted into the transmitter test interface, and no network interface should be inserted at the other end of the network cable.
2. The range must be 2.5m—200m, otherwise , it would be display the incorrect numbers or display as shown above (right).

SCAN (Cables tracking)
Do not connect with DC voltage over 60V or any AC voltage live circuit equipment or it will result damage. The cables tracking function has two modes: digital mode and Analog mode, The receiver and transmitter signals must be consistent to receive the signal.

• Connect one end of the target cable to the (SCAN) RJ45 socket at the head of the transmitter. Telephone cable can be connected to the RJ11 socket in the right of the transmitter.
• Select the “SCAN” menu and press “Enter” to transmit and show below:
• The receiver knob rotates clockwise with a “beep”. You can rotate clockwise to the maximum position with higher reception sensitivity.
• The receiver startup defaults in the digital signal receiver mode. You can press the “SCAN” key to switch to the receive signal mode. Analog signal reception mode, the SCAN indicator light flashes. Digital mode, the SCAN indicator is long and bright.
• 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.

PoE Testing

• Insert the network cable into the transmitter RJ45 socket (Flash/PoE/Length) at the head of the transmitter and the other end of the cable to the PoE switch.
• Select the “PoE” menu and press “Enter” to test.
• The display shows the test results: if the tested PoE switch is a standard PoE switch, display the PoE power supply mode, standard type, PoE voltage, voltage positive and negative electrode, etc. As shown in the figure below:
• The figure shows that the power supply line supplies power to 12 36 line, span mode is “End span”; standard type is IEEE 802.3at; voltage is 53.6V; polarity “-” means that the left two lines are negative voltage poles; if display “+” means that the left two lines are voltage “+” pole.
• If the tested device is non-standard PoE device, display as blow:
• The figure shows that the power supply line is 8 pins. Non-standard PoE equipment. Voltage is 53.6V; Voltage polarity is not displayed when 8 pins power supply.
• The test result can usually be displayed within a few seconds. If the test result is not displayed when the test time is more than 30 seconds, the tested device may not be a PoE switch, or the test interface may be wrong.

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.

• Insert the network cable into the transmitter RJ45 socket (Flash/PoE/Length) at the head of the transmitter and the other end of the cable to the network switch.
• Select the “Flash” menu and press “Enter” to start testing.
• 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.
• 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 “Time out” 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.

QC (RJ45 Connectors Testing)
QC: It is used to test whether the cable core is connected to the copper sheet of the RJ45 connector when you crimp a plug or not sure a plug is good.

• Insert the network cable (RJ45 plug) into the transmitter’s RJ45 (QC/CONT) socket.
• Select the “QC” menu and press “Enter” to start testing.
• The test result showing “√” indicates that the cable is normal. If “×” appears, the line is failed. As shown in the figure below:

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

• Select the “Setting” menu and press “Enter” to start setting.
• Backlight setting: Press the “Enter” key to set.
• Adjust the backlight time among 15S, 30S, 60S, on and off.
• Auto-off time setting: Press the “Enter” key to set.
• Adjust the Auto-off time among 15mins, 30mins, 1hour, off.
• Contrast setting:
• Select the “Contrast” to setting. And press “Right” or “Left” key to adjust the contrast to suit yourself.
• Version information : Press the “Enter” key to set.
• 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 AC70-1000V (50 / 60Hz).

• Tun on the receiver and press “NCV” key, The indicator light on.
• 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.

Note

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

Flashlight
Tun on the receiver and press “Lamp” key, the indicator and the front LED auxiliary lighting LED is turned on for lighting with insufficient light. Press the key again to tun off.

Charge the Product

The transmitter and receiver of this product are both built-in 3.7V 1400mAh lithium battery, TYPE-C charging interface, which can use the mobile phone or other USB charger to charge this product, but this product is not equipped with the charger.

• When the battery symbol of the transmitter display screen flashes, the receiver power indicator light flashes, indicating that the battery voltage is insufficient, please charge in time to avoid affecting the work.
• Please pull out the charger in time. Do not charge for a long time to avoid damage to the instrument.
  If this product is not used for a long time, please charge once every 3 months, so that the lithium battery remains active, to avoid damage to the lithium battery.
