Product Features:

The Multiple Pulse Cable Fault Tester complete set consists of the Cable Fault Tester main unit, cable fault testing accessories (path locator and fault locator), and the cable testing high-voltage unit, making testing simple and convenient.

1. The instrument adopts an industrial embedded computer platform system, full computer XP system operation platform, integrated software testing, and is equipped with cable fault testing software.

2. It features a 12.1-inch large-screen touch system with dual control via touch pen and touch mouse, high-brightness display suitable for outdoor sunlight use, lithium battery power supply for convenient on-site testing. The engineering aluminum alloy casing is shockproof and moisture-proof, ensuring excellent stability.

3. It uses a USB communication interface for stable signal acquisition. The main unit can automatically select five sampling frequencies from a minimum of 6.25MHz to a maximum of 100MHz, with adaptive pulse width, meeting the testing requirements for cables of different lengths, reducing coarse measurement errors, and improving testing accuracy.

4. The software implements automatic identification and search for both low-voltage pulse and multiple pulse methods, with automatic positioning of waveform fault inflection points. The fault distance is automatically read and displayed by the instrument. The same screen displays waveforms in three zones, and ten low-voltage pulse waveforms are randomly displayed for selection. It supports both automatic and manual processing modes, enabling dual cursor positioning on waveforms. The dual cursors can move to 0.15 meters, improving coarse measurement accuracy and reducing waveform errors.

5. The unique multiple pulse generator design allows three testing methods to be completed without rewiring on site. A single discharge can yield ten low-voltage short-circuit pulse waveforms, greatly reducing large oscillation interference. The multiple pulse generator is compact, weighing only 5KG, truly achieving lightweight complete equipment.

6. The Multiple Pulse Cable Fault Tester main unit supports built-in WiFi reception. The dedicated 3G software enables experts to provide real-time remote technical testing services at any time. Experts can remotely control the user's main unit, and the business technology is equipped with an Android version of the testing software, providing users with timely and accurate waveform analysis and communication guidance anytime, anywhere, ensuring worry-free work (optional).

7. Built-in on-site waveforms and physical wiring diagrams facilitate on-site testing comparison and daily learning, and can automatically generate test reports and print them.

8. The key fault locator part can directly display the distance from the tester to the fault point digitally. It adopts noise suppression technology, which is another innovation in domestic similar positioning technology, providing strong support for quickly and accurately locating cable faults and reducing power outage losses.

9. The high-voltage discharge part offers two options for users. The new 8.4kg high-frequency high-voltage power supply replaces the 65kg test transformer and operation box, with a wide range of applications, truly achieving comprehensive lightweight design.
