A brief introduction to the handheld fast detection cable fault tester

The handheld fast detection cable fault tester is an instrument that uses the pulse reflection method to perform rapid initial inspection of cables.

The pulse reflection sensitivity is high. When the reflected sound pressure is 1% of the initial sound pressure, it can be detected, and smaller defects can be found. The defect positioning accuracy is high. Since the sound path distance from the detection surface to the defect can be represented by the position of the defect wave on the time base axis of the fluorescent screen. Based on this, the defect can be located. Usually the horizontal linear error of the instrument is less than 2%. Therefore, this type of instrument has a high positioning accuracy and a high resolution for adjacent defects on different sound paths. It has a wide range of applications. Changing the coupling table and the probe phase type can realize different detection methods. The equivalent size of the defect can be determined. I recommend a TFND131 series cable fault tester to everyone. This device has added the function of intelligent waveform recognition. It is very easy to use

Instrument Introduction:

The D131 series cable fault intelligent distance meter is suitable for automatically measuring the precise location of core wire obstacles such as broken wires, mixed wires, and ground faults of power cables and communication cables.

The D131 series features automatic testing of many typical faults, with the following features:

1) DAGC (Digital Automatic Gain Control) system: Gain can be adjusted digitally. This eliminates the waveform distortion caused by the potentiometer knob of the original similar instruments. It can also make pure linear adjustments, which is conducive to manual testing.

2) Automatic digital waveform recognition technology: relies on machines to automatically recognize waveforms that are difficult for humans to judge.

3) The use of ARM CPU combined with FPGA technology can quickly perform various complex calculations and accurately determine fault waveforms.

4) Waveform comparison function, which is convenient for comparing the test waveforms of the faulty line and the normal line, and clearly locating the fault point.

5) Large color LCD display, humanized interface menu design, and quick digital keys make it easy for users to operate.

6) High-energy lithium battery, with a usage time of up to ten hours (charged with a dedicated charger).

7) Wave speed memory: after shutting down and restarting, the wave speed will be automatically set to the wave speed when it was shut down last time.
