functional operation

Line hunting function:

• Line hunting function: refers to quickly finding the required wires among many wires, network wires, and single cable wires.
• This instrument is used for RJ45 network cable interface and RJ11 telephone line interface hunting; other metal wires can be transferred through an adapter.
• Operation method: Turn on the transmitter and receiver, and turn on the transmitter and receiver line hunting function ()

Network cable hunting

• Insert the network cable directly into the RJ45 interface of the transmitter.
• When the receiver is close to the network cable to be found, the signal strength indicator will light up and a signal will beep.
• You can adjust the signal strength of the receiver through the knob to accurately find the network cable under test. The specific usage is as follows:

NOTE: The longest tracking distance is 300 meters, and it can be powered or unpowered.
The voltage of powered tracking cannot exceed 60V, otherwise it will burn the instrument.

Cable hunting:

• Multi-strand cable hunting (more than two strands), the instrument clip cable is inserted into the transmitter RJ11 interface, and the red or black (single clip) is used to clip a single cable hunting. Two cables cannot be used for hunting.
• The receiver is close. When the cable is sought, the signal strength indicator lights up and a signal sound is emitted.
• The specific usage method is as follows:

NOTE

• Only a single clip can be used for cable hunting, and two clips cannot be used at the same time.
• The longest tracking distance is 300 meters, and it can be powered or unpowered. The voltage of powered tracking must be lower than 60V, otherwise the instrument will be burnt out.

Finding cable breakpoints
Multi-strand cables cannot find breakpoints (more than two strands), and are limited to finding breakpoints on single wires Insert the clip wire into the transmitter RJ11 interface, and use a single clip (red or black) to clip a single wire for tracking, and the receiver When approaching the cable to be sought, the signal strength indicator lights up and a signal sound is emitted. After the cable breakpoint, the receiver signal strength and signal sound disappear. The position of the cable breakpoint is judged by the signal disappearing position. The specific usage method is as follows:

NOTE

• The short-circuit point search distance is up to 300 meters, and the position of the short-circuit point can be accurately found through the receiver knob to attenuate the signal strength.

Finding the short-circuit point of the cable
When the two cables are short-circuited, find the location of the short-circuit accurately, insert the clip cable into the transmitter RJ11 interface, and clip each of the red and black clips. When the receiver is close to the cable to be sought, the signal strength indicator will be on and a signal will sound. After the short-circuit point is passed The receiver signal strength indicator and signal sound disappear, and the short circuit position of the wire is judged by the signal disappearing position. The specific usage method is as follows:

NOTE: The short-circuit point search distance is up to 300 meters, and the position of the short-circuit point can be accurately found through the receiver knob to attenuate the signal strength.

Judgment of the positive and negative poles of DC voltage below 48V

• The transmitter RJ11 interface is inserted into the clip line, and the positive and negative poles of the DC voltage are arbitrarily connected.
• When the () indicator light is red, it means that the red clip is positive and the black clip is negative. The red light is off, the specific usage method is as follows:

NOTE: It is not allowed to measure the voltage higher than 48V, but to judge the positive and negative poles only when the voltage is lower than 48V.

network line to line detection

• The operation method is as follows:

1. Turn on the transmitter and the power indicator will light up. Press to select the alignment function, and the alignment button indicator will light up.
2. One end of the crystal head of the network cable is inserted into the RJ45 interface of the transmitter.
3. The other end of the network cable is inserted into the receiver RJ45 interface.
   Start to automatically detect the network cable, observe the lighting sequence of receiving and transmitter indicator lights to judge whether the wiring is correct. If the light sequence of receiving and transmitter is consistent, it is normal.

NCV non-contact AC voltage detection
The NCV function can perform non-contact voltage detection on live cables above AC 45V. When AC voltage is detected, the NCV indicator will light up the corresponding signal strength indicator (high, medium, low) according to the intensity of the induced voltage. At the same time, the buzzer emits alarm sounds of different frequencies. When the receiver is turned on, the power indicator light is on, press the () key, the NCV indicator light is on, when the induction probe is close to the wire or object to be tested, when the NCV probe senses an AC voltage signal, it lights up the signal strength indicator and sounds an alarm.
The operation method is as follows:

NOTE

• The non-contact detection voltage may be affected by different factors such as socket design, insulation thickness and type, and there may still be voltage even if there is no voltage indication.
• Do not rely solely on a non-contact AC voltage detector to determine whether a conductor has voltage.
• External environmental interference sources (such as switching power supplies, various chargers, motors, etc.) may falsely trigger non-contact voltage detection.

battery under voltage indication:

• Under voltage indication of transmitter and receiver: when the battery of transmitter and receiver is lower than the working voltage, the power indicator of the power on button will flash to prompt timely replacement of battery.
