Introduction
The Cable Fault Locator XHDD503B accurately identifies power cable fault points using the acoustic and magnetic synchronization method. An impact discharge generator produces electronic flashovers, which are detected and amplified by a specialized probe. The precise location of the fault is determined through auditory and visual cues. This device completes the precise positioning of cable faults within a rough measurement range and collects the time difference between acoustic and magnetic signals. It integrates positioning technology with path-assisted testing, offering multiple test modes and a variety of informative prompts to efficiently and accurately locate cable faults.
Features
1. Adopt acoustic-magnetic synchronous positioning technology to automatically calculate the acoustic-magnetic time difference and reduce pure dependence on sound monitoring.
2. The gain value and trigger value of the acoustic signal and magnetic signal can be adjusted manually to adapt to various environments.
3.5-inch touch-high brightness LCD ensures visibility under sunlight.
4. Built-in large-capacity lithium-ion battery power supply, equipped with fast charger.
5. Small, portable and light weight.
