1. The cable fault tester adopts an industrial embedded computer platform system, designed for industrial-grade environments to achieve extremely high stability. Powered by a lithium battery, it is convenient for on-site testing.
2. Featuring a 12.1-inch large touch screen system, it integrates software on a full computer operating platform, completely bidding farewell to the era of single-chip microcomputer cable testers, and is equipped with cable fault test management software.
3. Using a USB communication interface, the signal acquisition is stable. If paired with a laptop, it can achieve dual control and dual display. The host can automatically select from a minimum of 6.25MHz to a maximum of 100MHz sampling frequencies, meeting the testing requirements for cables of different lengths and reducing coarse measurement errors.
4. The software enables automatic fault search and automatic distance display. Dual cursors can be moved with precision up to 0.1 meters. Waveforms can be arbitrarily compressed or expanded, and two waveforms closer to the standard can be randomly displayed on the same screen for accurate comparison and analysis, improving test accuracy and reducing errors.
5. It can store multiple types of field waveforms and on-site physical wiring diagrams in memory, accessible with a single click. The cable data management software can perform comprehensive cable file management, providing reference and assistance for cable maintenance and precise location.
6. The intelligent combined sampler replaces cumbersome on-site wiring, making waveforms intuitive and easy to analyze. It is isolated from high voltage, ensuring absolute safety for the host and operators.
