Function introduction
1. Switch key: This switch is a self-locking switch; press it to turn on the power, the transmitter is in working state; pop up to disconnect the power supply, the transmitter is in a shutdown state.
2. Output port: This port is a multi-core dedicated aviation socket; it is used to change the output mode of the signal. Connecting the direct connection line is the direct connection mode; inserting the coupling clamp connection is the coupling mode; not connecting the line is the induction mode.
3. Liquid crystal display area: Display the required basic information.
4. Frequency key: This key is a jog soft switch; the frequency of the output signal can be changed every time it is pressed; the initial power-on is 577Hz. Initially 8KHz in sensing mode. In the frequency setting menu interface, press this key to select or cancel the frequency covered by the light bar; in the multi-frequency mode setting, press this key to choose to replace the output frequency channel.
5. Power key: This key is a jog soft switch; the output power can be changed once every time it is pressed, and it can be selected from low-grade, mid-grade, high-grade and full-grade. Flip through the frequency menu; in multi-frequency mode setting, press this key to select the output frequency.
6. Menu key: This key is a jog soft switch; press this key to cycle into the frequency setting menu, resistance measurement mode, and multi-frequency mode setting.
7. Charging port: This port is a Φ2.1 charging stand; it is used to connect a special charger to charge the battery.

Signal output mode - transmitter working mode
The transmitter can output different AC signals, which can be applied to the target cable in three ways (direct connection, clamp coupling, induction). To ensure reliable signal transmission on the target cable, there must be a reliable loop in the line. It can be an indirect loop composed of the ground, a capacitive loop composed of a distributed capacitance formed between a long enough cable and the ground, or a direct loop composed of short-circuit fault points between lines. Clamp coupling method is suitable for live cable. Different circuits meet different tests.

Brief introduction to the receiver

Receiver panel and function introduction
A receiver is an integration of a system circuit capable of receiving a specific magnetic field and converting it into an electrical signal to display it and prompt the operator. It is the second core of this set of instruments. It is fully functional, highly intelligent, portable, lightweight, and easy to operate. 

Receiver characteristics
1) Cable positioning: Select the wave crest method and use parallel antenna positioning to quickly track the target cable. When it is above the cable, the signal is the largest and the two sides are reduced. Choose the valley method and use the vertical antenna for positioning. When there are no adjacent cables and interference sources, the positioning is more accurate and reliable. When the receiver is above the cable, the signal is the smallest and the signal on both sides is large.
2) Depth measurement: In direct connection mode, the depth is measured directly. Place the receiver directly above the pipeline, and keep the instrument body still when the direction indicated by the compass points straight ahead, and the real-time sounding value is displayed in the upper left corner.
Voice prompt
A great feature of this instrument is that it has a voice prompt, which can reduce the operator's eye fatigue when working for a long time, and make the detection work more simple and clear. The volume of the sound emitted by the receiver is proportional to the strength of the received signal. Under unity gain, when the sound from the receiver is loud and rapid, it means that the received signal is strong, and vice versa, it means that the received signal is weak. When the receiver is in the crest method, the sound is loudest and sharp right above the cable, and the sound is small and sparse on both sides. When the receiver is in the valley method, the sound is the smallest and most sparse right above the pipeline, and the sound is loud and tight on both sides.
Receiver working mode
working principle
When a signal is applied to the cable, there is a current on the cable, and the current generates a magnetic field that radiates around the cable. The frequency of the magnetic field is consistent with the frequency of the applied signal. The strength is the cable as the center of the circle and the radiation is decreased, and the direction is the tangent direction of a certain point on the radiation circle.
The receiver receives the magnetic field signal or the leaked electric field signal radiated by the cable through the internal antenna or external input device, and can be processed in two different working modes, and the signal strength change is prompted to the operator.
