1. The signal transmission connection mode of the transmitter: direct connection method, coupling method, induction method.
2. Receiver working mode: wave peak method, wave valley method, step voltage method.

This XHGX507X underground cable pipe locator uses the electromagnetic field signal of the underground cable to locate the cable, and gives the depth and current readings, so as to realize the cable detection function.

Transmitter Features:
★Displays the current output frequency.
★Display the current output power; it can display low-grade, mid-grade, high-grade and full-grade respectively.
★Display the current working mode; can display direct connection, coupling, induction respectively.
★Displays the current loop current value; the effective display is 0-999 mA.
★Display the current loop impedance value; the effective display is 00001 - 20000 ohms.
★Indicates the current battery level; it is represented by a battery symbol, all black is full power, and the left side is the current battery percentage display.

Receiver Features:
The device shows the current receiving frequency value, which starts at 577Hz when powered on. The signal strength is represented in two ways: first, by the length of the grating that moves from both sides to the middle, indicating that the signal is too strong or out of range when the grating is full; and second, by a number ranging from 00.0 to 99.9, with 99.9 indicating an overly strong or out-of-range signal. A colored compass indicates the direction of the pipeline, while the depth of the measured underground line and the current on the line are also displayed. The gain is automatically adjusted by default, covering a dynamic range of 000-140db, starting at 60db upon initial boot. The receiver can display various signal reception modes, including narrow peak, wide peak (default at power-on), trough, broad peak arrow, peak + trough, and external equipment (which is automatically recognized). The current battery level is indicated by a battery symbol. The buzzer’s working status is shown with a horn symbol plus lines: one line for low loudness, two for medium, three for high, and a cross to turn it off (default at power-on). When the cable is turned off, an arrow appears to indicate the cable location, with two arrows appearing above the cable. When using the SS frequency, the device displays the direction of the signal current to assist in pathfinding and shows the signal’s phase, which can be cleared by long-pressing the frequency key.

Function
1) It can quickly and effectively determine the direction and depth of underground cable /metal pipelines. It can also identify power outages and live cables, and use the A-frame to accurately locate low-resistance cable faults to ground.
2) It has signal strength indication, left and right arrow indication, and compass direction indication.
3) The maximum depth of the detection pipeline can reach 20 meters.
4) Automatic sounding: When the instrument is placed above the pipeline, it will automatically display the true depth of the target pipeline.
5) Signal identification: Accurate identification of cables from three dimensions of signal amplitude, signal direction and signal phase.
6) Current direction indication: It can track the current direction and phase of the signal, effectively improving the accuracy of the search path.
7) The 70% sounding method of automatic prompting can easily determine the 70% signal point through graphics and prompt sounds.
