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, 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. 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.
Interface display content function introduction
Receiver Broad Peak Arrow Mode Interface
Frequency: Display the current receiving frequency value; the initial value is 577Hz when power on.
Grating: The signal strength is indicated by the length of the grating; the grating moves from both sides to the middle, and the signal is too strong or out of range when the grating is full.
Three digits: the signal strength is indicated by the size of the number; the valid range is 00.0-99.9, when 99.9 is displayed, the signal is too strong or out of range.
Color compass: indicates the direction of the pipeline.
Depth & Current: Indicates the measured depth of the underground pipeline and the current on the pipeline.
Gain: Indicates the magnification of the signal currently processed by the receiver, with a dynamic range of 000-140db; it is automatically adjusted by default. The initial boot is 60db.
Mode: Indicates the way the receiver receives the signal, and displays narrow peak , wide peak , trough , broad peak arrow , peak + trough and external equipment ; the initial power-on is wide peak. External devices are automatically recognized.
Battery level: Indicates the current battery level; it is indicated by the battery symbol.
Volume: Indicates the current working status of the buzzer, represented by the horn symbol plus a line, one line is low loudness, two lines are medium loudness, three lines are high loudness, and a cross is to turn off the buzzer. The initial power-on is to turn off the buzzer.
Left and Right Arrows: Arrows automatically appear off the cable to indicate the cable location ; two arrows appear above the cable.
Current direction: When using the SS frequency, this function can display the direction of the signal current to assist the operator in path finding.
Phase Indication: When using the SS frequency, the receiver will display the phase of the signal. Long press the frequency key to clear the phase.

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.
