The multi-function cable route and fault tester features a 2.8-inch OLED screen with high contrast and clear display even under strong sunlight, supporting one-key operation for quick fault detection and route tracing. It has a signal frequency range of 16Hz to 1MHz, adapting to various types of cables and metal pipelines, with a route tracing distance of 10km and fault detection distance of 8km. The device supports storage of 500 groups of test records and Bluetooth 5.0 data transmission, allowing users to import test data to mobile phones for analysis and archiving. With IP53 dust and splash protection grade, it can adapt to various outdoor working environments, and is powered by 3*AA batteries, providing up to 10 hours of continuous working time.

Detailed specifications of this tester include signal frequency range of 16Hz to 1MHz, route tracing distance of 10km, fault detection distance of 8km, fault positioning accuracy of ±0.5% of the measured distance, operating temperature range of -10℃ to 55℃, storage temperature range of -20℃ to 60℃, built-in battery life of 10 hours, dimensions of 180*120*70mm and weight of 0.8kg. It has IP53 protection grade, supports Bluetooth 5.0 connection, can identify common cable fault types including open circuit, short circuit and ground fault, and supports real-time signal strength display for route tracing.

This multi-function cable route and fault tester is widely applicable to communication optical cable laying maintenance, urban underground pipeline inspection, power weak current wiring maintenance, industrial comprehensive wiring route tracing and fault detection scenarios. It is an ideal tool for weak current engineers, pipeline maintenance personnel and on-site wiring teams, suitable for complex environments such as urban underground pipe galleries and industrial parks.
