• Short press “ ” to switch VFL output mode： CW/Glint/OFF. The “ ” icon will be displayed in sync status.
• Short press “ ” to turn on/off LED lighting.
  The “ ” icon will be displayed in sync status.

Network Cable Test(Module)

Unplug the network cable test module, short press “ ” to enable the network cable test , the “ ” icon will display the synchronization status. Connect both ends of the network cable to the host and module respectively. You can judge whether the network cable is qualified based on the lighting status of the host UI (1,2,—8,G) and module indicators corresponding. ” ” flashes to indicate that the network cable is plugged into the RJ45 test socket on the left.

Network Cable Test(Receiver)

Short press “ ” to enable the network cable test , and the “ ” icon will display the synchronization status.
Connect both ends of the network cable to the host and module respectively. You can judge whether the network cable is qualified based on the lighting status of the host UI (1,2,—8,G) and module indicators corresponding.

Network Cable test-Crimping Function

Short press “ ” twice to enable the network cable test crimping function, and the “ ” icon will be displayed in sync status.
Connect the tested connector to the RJ45 test socket on the left side of the host. You can judge whether the network cable is qualified according to the lighting status of the host UI indicator. “ ” lights up if the crimping test fails, and the LED light flashes corresponding to the core number of the failed crimping wire. “ ” lights up and the crimping test is passed.
“▶” flashes to indicate that the network cable is plugged into the RJ45 test socket on the left.

Network Cable Tracing-Host Settings (Analog)

Short press “ ” three times to turn on the cable tracing function (analog), the “ ” icon will display the synchronization status, and the “ ” LED will flash continuously.
Connect the cable connector to the RJ45 test socket on the right side of the host. At this time, the host setting of the cable tracing function is completed and to set the receiver.
” ▶” flashes to indicate that the network cable is plugged into the RJ45 test socket on the right.

Network Cable Tracing-Receiver Settings (Analog)

The red indicator light is on, indicating that the receiver is  in analog signal receiving mode, and the greenindicator light is on, indicating  that the receiver is in digitalsignal receiving mode.

Turn the receiver knob clockwise to turn the receiver on. Short press “ ” to turn on the cable tracing function (analog). At this time, the receiver will beep and the red backlight of the button will light up.
When the probe gradually approaches the test network cable, the receiver will emit regular beep reminders and the light ring above will flash. The adjustment knob on the receiver is used to adjust the sensitivity (clockwise to the end for the highest sensitivity).
▲Note: When searching for cables in the network, due to the network switch (the transmitter transmits the signal and transmits it to other network cable ports through the internal circuit of the switch), several network cables close to the target network cable may have audio signals. In this case, you can try to turn the receiver sensitivity knob counterclockwise to reduce the receiving sensitivity to find the target network cable.
Note: The modes of the host and receiver need to be consistent, otherwise the signal will not be received.

Network Cable Tracing-Host Settings (Digital)

Short press “ ” four times to turn on the cable tracing function (digital), the “ ” icon will display the synchronization status, and the “ ” LED will flash continuously.
Connect the cable connector to the RJ45 test socket on the right side of the host. At this time, the host setting of  the cable tracing function is completed and to set thereceiver.
“▶” flashes to indicate that the network cable is plugged into the RJ45 test socket on the right.

Network Cable Tracing-Receiver Settings (Digital)

Turn the receiver knob clockwise to turn the receiver on. Short press “ ” to turn on the cable tracing function (digital). At this time, the receiver will beep and the green backlight of the button will light up.
When the probe gradually approaches the test network cable, the receiver will emit regular beep reminders and the light ring above will flash. The adjustment knob on the receiver is used to adjust the sensitivity (clockwise to the end for the highest sensitivity).
▲Note: When searching for cables in the network, due to the network switch (the transmitter transmits the signal and transmits it to other network cable ports through the internal circuit of the switch), several network cables close to the target network cable may have audio signals. In this case, you can try to turn the receiver sensitivity knob counterclock- wise to reduce the receiving sensitivity to find the target network cable.
Note: The modes of the host and receiver need to be consistent, otherwise the signal will not be received.

Receiver- NCV Function

Turn the receiver knob clockwise to turn the receiver on. Short press “ ” to turn on the NCV mode. When a voltage greater than the threshold is detected, the receiver horn will make a “beep” sound, and the ring light on the probe will flash.
Note: Nearby external interference sources (such as the charger without grounding, etc.) may trigger non-contact voltage detection.
Even if there is no indication, voltage may still be present. Don’t rely solely on a non-contact voltage detector to determine whether voltage is present on a wire. Detection operations may be affected by factors such as socket design, insulation thickness and type.

Receiver-LED light function

Turn the receiver knob clockwise to turn the receiver on. Short press “ ” to turn on the LED light function.

Data Communication

Communication: Use a USB-C data cable to connect the host to the PC, install the communication software on the PC to perform data transfer operations. The “ ” icon flashes, indicating that communication is in progress.
