The DA50 is a telescoping AC current detector designed for non-contact detection of AC current up to 1000A in shielded wires, wires behind walls, metal circuit breaker boxes, and junction boxes. It features a telescoping probe that extends to 0.9m (36") with a total reach distance of 1m (39"), enabling measurements in hard-to-access areas without requiring a ladder. The detector offers sensitivity adjustment from 200mA to 1000A at 50/60Hz, with red and green LED indicators, switch-controlled ON/OFF operation, and an audible beeper for user feedback. Powered by two LR44 button batteries, the DA50 is rated for CAT IV-600V and CAT III-1000V safety categories, making it suitable for electrical troubleshooting, circuit verification, and maintenance applications where safe, non-contact current measurement is essential.
