Functional operation
1. Hunting function:
Hunting function is to find the lines required from numerous lines, and the
instrument is applicable for direct hunting of RJ45 interface network cable, and
RJ11 interface telephone line; the hunting of other metallic conductors could be
switched via adapter, with query function on optical fiber circuit (only WT-58DL).
Operation method:

a) Power on the transmitter, the power indicator lights up, and the transmitter
starts to work.
b) Connect one end of the cable to be tested to corresponding port (i.e. RJ45,
RJ11) of the transmitter or connect to the RJ11 port via adapter.
c) Press the hunting function key ( ) of the transmitter, the transmitter starts
to send digital signals to the cable to be tested.
d) Power on the receiver, the power indicator lights up, and the receiver starts
to work. Press the hunting function key ( ) of the receiver, the receiver
starts to receive digital signals in the cable.
e) Hold the receiver in hands, and detect at the other end (such as the
surrounding of stacks of telephone line distribution cabinet, junction box,
hub, switch etc.) of the cable to be tested. By comparing the sound sent by
the receiver, and signal indicator strength, the cable sending out the loudest
sound with the strongest signal indicator when getting close to the probe is
the one in need.
f) During detection, the volume could be changed by adjusting the volume
adjustment knob on the receiver, to adapt to the actual environment.
g) Use accessories with a clip to insert into RJ45 or RJ11 interface, and clamp
the black clip onto the ground wire (i.e. water pipe, building grounding or
equipment metal shell etc.) to increase the line inspection distance.
Note: When used in places subject to loud noise, use the headphone jack of the
headphone receiver to help hunting.
2. Network cable alignment detection:
Operation method:
a) Power on the transmitter, and turn on the power indicator, the transmitter
starts to work, and then press the alignment function button, the alignment
indicator lights up.
b) Insert one end of the network cable onto the RJ45 socket of the transmitter.
c) Insert the other end of the network cable onto the RJ45 socket of the
receiver.
d) System starts to detect, and the alignment indicator will display the
detection result.
e) Long press the ( ) button for 2 seconds, the indicator lights up, and the red
light pen emits red laser, after that, insert the optical fiber connector into
the emission of the red light pen (only WT-58DL).
3. Non-contact AC voltage detection (NCV)
The NCV function could realize non-contact detection on live conductor with
power frequency above 45V, when any AC voltage is detected, NCV indicator
will behave according to different induced voltage strengths, the signal
strength indicator will light up, and the receiver will make an alarm sound.
Operation method:
a) Power on the receiver, the power indicator lights up, and the receiver starts
to work.
b) Press the NCV key, the NCV indicator lights up, and close the inductive
probe to the conductor or article to be tested.

c) When any voltage is detected, the receiver will light up the signal strength
indicator and will make an audible alarm.
Note: Detection may be impacted by factors such as different socket designs, and
insulation thickness types etc. Even if there's no indication, voltage may still exist. Do
not judge whether there's voltage in lead completely depending on non-contact
voltage detector.
Interference sources from external environment (i.e. flash light, motor, mobile
phone charger, switching power supply etc.), may trigger non-contact voltage
detection by mistake.
3. Battery undervoltage indication:
Undervoltage indication of transmitter and receiver: When the battery of
transmitter or receiver is lower than the working voltage, the power indicator of the power
button will flash. Please replace the battery timely when the indicator flashes.
