XHHD530M Low voltage concealed cable tester
Description
The hidden line fault detector is a specialized instrument designed for power, broadcasting, post and telecommunications departments, as well as industrial and mining enterprises and rural areas to locate underground cables, including direct buried armored cable lines and buried line faults. It is capable of detecting the direction of the buried line, the precise underground position, the basic burial depth, and various types of ground leakage faults and broken core faults. This includes lines buried under paddy fields, cement roads, brick and stone surfaces, asphalt roads, and within the walls of buildings. Waterproof wires and cables used above ground can also be detected using this instrument with appropriate methods.
Transmitter
|
The transmitter panel is equipped with "power switch", "power indication"; "output selection", "high, medium, low"; "output indication" and "K measurement" switching switches, and the indicator light indicates the switching position; "output·KΩ measurement" shares an output terminal, which is switched by the "output·indication" and "KΩ measurement" switches; set "output 2" output terminal; square meter head indicates output and KΩ resistance. It can check the line on, off, mixed, and measure the size of the ground leakage resistance.

Instrument principle and structure
This instrument consists of a transmitter, a receiver, a probe and a head, a pair of plugs and plugs, connecting wires, etc.
Transmitter (1) Mainly outputs continuous pulse signals, which is the signal source for finding faults. (2) kΩ function, can detect the continuity, disconnection, mixing and leakage resistance of the line, and determine the nature and type of fault. (3) "Output 2" output terminal outputs large current
