Acoustic and Magnetic Digital Display Squelch Pointer Manufacturer Acoustic Magnetic Digital Display Noise Squelch Pointer Instructions for Use Do not switch the power supply of the main unit too frequently. The cable fault tester is equipped with a USB socket on the front or back panel, and the base can be used for hot-plugging of USB devices such as USB flash drives, but must be deployed after the data transfer is complete.
In order to ensure the safe and reliable operation of the Windows operating system installed in the industrial microcomputer, please never remove or modify the official documents on the hard disk and the logo on the desktop. Do not rashly operate, modify, accumulate, delete and use the placed Windows system, so as not to cause the operating system to be destroyed. The cable fault locator is equipped with a sound test method point instrument, which can be used to accurately define the proper sentinel of the fault point.
Performance characteristics: 1. This product is used for rapid and localization of buried fault points and accurate detection of cable burial paths and burial depths. 2. The special structure of the acoustic vibration sensor and the special low-noise device are used for pre-amplification, which greatly improves the sensitivity of the instrument's fixed point and path detection. In signal processing technology, the distance between the fault point and the sensor probe is digitally displayed, which greatly eliminates the blindness of fixed point.
3. For the overhead faulty cable in the cable trench, when the point was fixed in the past, the vibration sound of the whole cable made any pointing instrument helpless and could not determine the specific location of the closed fault. Now, simply touch the instrument's sensor probe to the faulty cable or a nearby cable, and the fault distance can be accurately displayed, and the fault location can be quickly and effortlessly determined. 4. Power frequency adaptive cancellation theory and high-Q power frequency notch technology greatly strengthen the suppression and anti-interference ability of 50Hz power frequency signal in strong power frequency electric field environment, and reduce fixed-point blind spots.
In the function of the instrument, the use of sound and electricity synchronous reception and display technology effectively overcomes the difficult problem of fixed point caused by environmental noise interference at the fixed point. In particular, the digital display of the fault distance saves the operator from analyzing and judging complex waveforms, and replaces the rough distance measurement function of the flash tester to a considerable extent. For a faulty cable with a length of several hundred meters, it is generally possible to implement a fixed point without rough measurement, which truly achieves high efficiency, speed and accuracy.
The use of 15KHz amplitude modulation electromagnetic wave and amplitude detection technology for path detection and cable burial depth measurement avoids the interference of the TV horizontal frequency on the pointing device when the original equal-amplitude 15KHz signal source is used. 5. The operation is extremely simple, just turn on the power switch, and there is no need to shift gears and select functions. The structure is compact, small and modular, easy to carry and maintain, and has powerful functions.
